abstract = {Autism spectrum disorder (ASD) is a developmental disorder that is characterized by deficits in social communication and restricted, repetitive, and stereotyped behaviors. In addition to neurobehavioral symptoms, children with ASD often have gastrointestinal symptoms (e.g. constipation, diarrhea, gas, abdominal pain, reflux). Several studies have proposed the role of gut microbiota and metabolic disorders in gastrointestinal symptoms and neurodevelopmental dysfunction in ASD patients; these results offer promising avenues for novel treatments of this disorder. Interventions targeting the gut microbiota - such as fecal microbiota transplant (FMT), microbiota transplant therapy (MTT), probiotics, prebiotics, synbiotics, antibiotics, antifungals, and diet - promise to improve gut health and can potentially improve neurological symptoms. The modulation of the gut microbiota using MTT in ASD has shown beneficial and long-term effects on GI symptoms and core symptoms of autism. Also, the modulation of the gut microbiota to resemble that of typically developing individuals seems to be the most promising intervention. As most of the studies carried out with MTT are open-label studies, more extensive double-blinded randomized control trials are needed to confirm the efficacy of MTT as a therapeutic option for ASD. This review examines the current clinical research evidence for the use of interventions that target the microbiome - such as antibiotics, antifungals, probiotics/prebiotics, synbiotics, and MTT - and their effectiveness in changing the gut microbiota and improving gastrointestinal and neurobehavioral symptoms in ASD.},

abstract = {BACKGROUND: Rheumatoid arthritis (RA) with cold pattern is an important type of RA according to the theory of traditional Chinese medicine. Fuzi (also known as the lateral roots of Aconitum carmichaelii Debx.) represents a typical traditional Chinese medicine that has been clinically used for treatment of the RA especially cold-related RA for thousands of years, yet its mechanism remains unknown.

PURPOSE: The purpose of the research was to study the therapeutic effects of Fuzi on cold-related RA, and to investigate the mechanism of its action.

METHODS: Here, we investigated the pharmacological effects of Fuzi on cold-related RA using micro-CT, histopathological analysis, and inflammatory cytokine test. Then, a gut microbiota composition analysis in combination with fecal microbiota transplantation were used to confirm the role of gut microbiota in the therapeutic effects of Fuzi. Further, targeted bile acid metabolomics was used to screen the possible differential microbial bile acids involved in the mechanism of Fuzi. In vitro bioactivity analysis of differential bile acids was used to assess their anti-inflammation activity. Finally, western blot was used to investigate the signaling pathways of Fuzi in reducing the inflammation of cold-related RA.

RESULTS: The results showed that Fuzi alleviates cold-related RA by improving arthritis index, paw swelling, bone damage, and inflammatory cytokines. In addition, the ameliorative effect of Fuzi is dependent on gut microbiota such as the taxa Lachnospiraceae and Ruminococcaceae. Targeted analysis of fecal and serum bile acids showed that TCA and THDCA were the main differential metabolites. In vitro, TCA and THDCA showed anti-inflammation effects on RAW264.7 cells. Western blot showed that Fuzi regulates TGR5-cAMP-PKA signaling and NLRP3 inflammasome to reduce cold-related arthritis.

CONCLUSION: Overall, our results demonstrated that Fuzi could regulate gut microbiota and microbial bile acid metabolism, the microbial metabolite THDCA acts on TGR5-cAMP-PKA signaling pathway and NLRP3 inflammasome to reduce cold-related arthritis. Our study suggests that supplementation of Fuzi or THDCA can be of great value for the prevention and clinical treatment of cold-related RA.},

abstract = {BACKGROUND: Fecal microbiota transplantation (FMT) transfers fecal matter from a donor into the gastrointestinal tract of a recipient to induce changes to the gut microbiota for therapeutic benefit; however, differences in the composition of gut microbiota after FMT via different donor material delivery routes are poorly understood. In this study, we first developed a novel technique for FMT, magnetic navigation technology(MAT)-assisted proximal colon enemas, in healthy Sprague-Dawley rats. Besides, the difference in fecal microbiota composition after FMT via oral gavage and proximal colon/cecum enemas was determined in antibiotic knock-down rats, in addition to the impact on intestinal barrier function.

METHODS: A device consisting of an external magnet and a magnet-tipped 6 Fr tube was used in the MAT group (n = 6), and the control group (n = 6) where fecal matter was delivered without magnetic navigation. The feasibility and safety of this method were assessed by angiography and histology. Next, the fecal microbiota of donor rats was transplanted into antibiotic knock-down rats via oral gavage (n = 6) and MAT-assisted proximal colon/cecum enema (n = 6) for a week. Analysis of fecal 16 S rRNA was conducted to determine differences in the composition of gut microbiota between different groups. The rat intestinal barrier integrity were evaulated by H&E and ZO-1/MUC2 immunofluorescence staining.

RESULTS: The end of the fecal tube could be placed in the cecum or proximal colon of rats in MAT group; however, this was rarely achieved in the control group. No colon perforation or bleeding was detected in either group. After fecal microbiota transplantation, the microbiota α-diversity and β-diversity were comparable among the different delivery routes.At the family level, the relative abundances of Muribaculaceae, Oscillospiraceae, and Erysipelotrichaceae were higher in the gavage treatment group, whereas Lactobacillaceae and Saccharimonadaceae were higher in the enema treatment group (all p < 0.05). FMT by enema was superior to gavage in maintaining the integrity of the rat intestinal barrier, as assessed by an elevation in the density of goblet cells and increased expression of mucin-2.

CONCLUSIONS: Fecal microbiota tube placement using magnetic navigation was safe and feasible in rats.Different delivery route for FMT affects the gut microbiota composition and the integrity of the rat intestinal barrier. Future experimental designs should consider the colonization outcomes of critical microbial taxa to determine the optimal FMT delivery routes in scientific research as well as clinical practise.},

abstract = {Ulcerative colitis (UC) is an inflammatory bowel disease characterized by recurrent colonic inflammation. Standard treatments focus on controlling inflammation but remain ineffective for one-third of patients. This underscores the need for alternative approaches, such as fecal microbiota transplantation (FMT), which transfers healthy donor microbiota to patients. The role of viruses in this process, however, remains underexplored. To address this, we analyzed the gut virome using metagenomic sequencing of enriched viral particles from 320 longitudinal fecal samples of 44 patients enrolled in the RESTORE-UC FMT trial. Patients were treated with FMTs from healthy donors (allogenic, treatment) or themselves (autologous, control). We found that colonic inflammation, both its presence and location, had a greater impact on the gut virome than FMT itself. In autologous FMT patients, the virome was unstable and showed rapid divergence over time, a phenomenon we termed virome drift. In allogenic FMT patients, the virome temporarily shifted toward the healthy donor, lasting up to 5 weeks and primarily driven by microviruses. Notably, two distinct virome configurations were identified and linked to either healthy donors or patients. In conclusion, inflammation strongly affects the gut virome in UC patients, which may lead to instability and obstruct the engraftment of allogeneic FMT.},

abstract = {INTRODUCTION: Clostridioides difficile infection (CDI) is a significant cause of antibiotic-associated diarrhea with high morbidity and mortality, particularly in cases of fulminant disease. Fecal microbiota transplantation (FMT) has demonstrated efficacy in treating severe and refractory CDI, typically administered via colonoscopy. However, in cases complicated by toxic megacolon, alternative methods of FMT delivery may be necessary.

CASE REPORT: This case report describes a 46-year-old female with cirrhosis and fulminant CDI complicated by toxic megacolon. Due to the patient's hemodynamic instability and contraindications to endoscopic FMT delivery, a novel approach of nasogastric FMT administration was utilized. The patient received a combination of enema-delivered and nasogastric FMT alongside standard antibiotic therapy. This approach resulted in rapid clinical improvement, with resolution of toxic megacolon, normalization of inflammatory markers, and avoidance of colectomy.

DISCUSSION: This report highlights the successful use of nasogastric FMT in a patient with fulminant CDI, offering a potential alternative delivery route when colonoscopic administration is contraindicated. To our knowledge, this is the first reported case of nasogastric FMT successfully resolving C. difficile-associated toxic megacolon.},

abstract = {The gut microbiota is a diverse ecosystem that significantly impacts human health and disease. This article focuses on how the gut microbiota interacts with inflammatory bowel diseases and colorectal tumors, especially through immune regulation. The gut microbiota plays a role in immune system development and regulation, while the body's immune status can also affect the composition of the microbiota. These microorganisms exert pathogenic effects or correct disease states in gastrointestinal diseases through the actions of toxins and secretions, inhibition of immune responses, DNA damage, regulation of gene expression, and protein synthesis. The microbiota and its metabolites are essential in the development and progression of inflammatory bowel diseases and colorectal tumors. The complexity and bidirectionality of this connection with tumors and inflammation might render it a new therapeutic target. Hence, we explore therapeutic strategies for the gut microbiota, highlighting the potential of probiotics and fecal microbiota transplantation to restore or adjust the microbial community. Additionally, we address the challenges and future research directions in this area concerning inflammatory bowel diseases and colorectal tumors.},

abstract = {BACKGROUND: Immunosuppressant administration subsequent to organ transplantation exerts a substantial influence on gut microbiota composition, thereby affecting patients' prognosis and quality of life.

METHODS AND RESULTS: We conducted a retrospective analysis involving 18 patients who experienced severe diarrhea or recurrent urinary tract infection (rUTI) due to prolonged immunosuppressant usage after kidney transplantation. Following episodes of severe diarrhea or rUTI, these individuals underwent fecal microbiota transplantation (FMT), resulting in notable alleviation of clinical symptoms. No unexpected adverse or serious adverse events were reported. In comparison to the pre-FMT period, the α-diversity of the intestinal microbiota in patients did not exhibit a significant difference following FMT; however, there was a notable distinction in the β-diversity and analysis of similarity (ANOSIM). In addition, our findings indicated a significant decline in the relative abundance of the bacterial genera Veillonella, Enterococcus, and Oribacterium, whereas a marked elevation was observed in the relative abundance of Faecalibacterium, Roseburia, Sutterella, Parasutterella, and Ruminiclostridium 5 after FMT in patients. Furthermore, there was a notable alteration in the metabolic pathway of gut microbiota in patients following FMT, with a significant enrichment observed in pathways such as Flavone and flavonol biosynthesis, Cytoskeleton proteins, Chromosome-related processes, NOD-like receptor signaling pathway, Progesterone-mediated oocyte maturation, and Antigen processing and presentation.

CONCLUSION: FMT exhibited an effective approach for managing rUTI and diarrhea arising from postoperative immunosuppressant exposure in kidney transplant recipients.},

However, ICIs can cause a diverse range of immune-related adverse events (irAEs) that present a considerable challenge to the efficacy and safety of these treatments. The gut microbiota has been demonstrated to have a crucial role in modulating the tumour immune microenvironment and thus influences the effectiveness of ICIs. Accumulating evidence indicates that alterations in the composition and function of the gut microbiota are also associated with an increased risk of irAEs, particularly ICI-induced colitis. Indeed, these changes in the gut microbiota can contribute to the pathogenesis of irAEs. In this Review, we first summarize the current clinical challenges posed by irAEs. We then focus on reported correlations between alterations in the gut microbiota and irAEs, especially ICI-induced colitis, and postulate mechanisms by which these microbial changes influence the occurrence of irAEs. Finally, we highlight the potential value of gut microbial changes as biomarkers for predicting irAEs and discuss gut microbial interventions that might serve as new strategies for the management of irAEs, including faecal microbiota transplantation, probiotic, prebiotic and/or postbiotic supplements, and dietary modulations.},

This review investigates the core mechanisms driving demyelination, its clinical impact, and emerging therapeutic strategies aimed at maintaining or restoring myelin integrity. Disruption of myelin impairs crucial neural communication pathways, resulting in cognitive, motor, and behavioral deficits that substantially reduce quality of life and create significant economic and social challenges. Key contributors to demyelination include genetic predisposition, environmental triggers, immune dysregulation, neuroinflammation, and alterations in the gut-brain axis mediated by the vagus nerve. Promising therapies include sphingosine 1-phosphate receptor modulators and muscarinic acetylcholine receptor antagonists, both of which diminish immune-related myelin damage and may enhance neuroprotection. In addition, the novel antidepressant arketamine appears to boost myelination through transforming growth factor-β1 signaling pathways. Approaches targeting the gut-brain axis, such as noninvasive transcutaneous auricular vagus nerve stimulation and fecal microbiota transplantation, may also help reduce inflammation and support myelin repair. Future research should center on clarifying the precise molecular mechanisms of demyelination, developing targeted therapies, and leveraging advanced neuroimaging for earlier detection and personalized treatment. By combining immunomodulatory and neuroprotective strategies, there is potential to significantly improve outcomes for individuals affected by demyelinating psychiatric and neurological disorders.},

abstract = {Aging is a primary driver of the escalating prevalence of heart failure (HF). Age-associated gut microbiota dysbiosis has been implicated in various age-related diseases, yet its role in age-related HF remains largely unexplored. In this study, we sought to explore the potential link between age-related gut microbiota alterations and HF in the elderly. We analyzed a publicly available single-cell sequencing dataset, which revealed markedly increased ferroptosis activity in cardiac myocytes of elderly individuals compared to their younger counterparts. Notably, treatment with the ferroptosis inhibitor, ferrostatin-1, mitigated cardiac ferroptosis and prevented cardiac dysfunction in aging rats. Furthermore, fecal microbiota transplantation from elderly HF patients significantly increased cardiac ferroptosis activity and induced cardiac dysfunction in healthy recipient rats. Integrated 16S rRNA sequencing and PCR quantification revealed a marked depletion of Faecalibacterium prausnitzii (F. prausnitzii) in elderly individuals, with a more pronounced decline in elderly patients with HF. Oral administration of F. prausnitzii or its metabolite butyrate effectively attenuated age-related HF through inhibiting ferroptosis. Additionally, gene-editing techniques were employed to generate F. prausnitzii BCoAT mutant deficient in butyrate production. Intriguingly, the protective effect was lost in the butyrate-deficient F. prausnitzii strain. Mechanistically, butyrate reduced intracellular iron accumulation and suppressed ferroptosis by downregulating LCN2 expression in senescent cardiomyocytes. Our findings highlight the critical role of aged microbiota-induced ferroptosis in HF and propose F. prausnitzii or butyrate may serve as potential targets for the prevention and treatment of age-related HF.},

abstract = {Neurodegenerative disorders such as Alzheimer's disease (AD), the most common form of dementia, represent a growing global health crisis, yet current treatment strategies remain primarily palliative. Recent studies have shown that neurodegeneration through complex interactions within the gut-brain axis largely depends on the gut microbiota and its metabolites. This review explores the intricate molecular mechanisms linking gut microbiota dysbiosis to cognitive decline, emphasizing the impact of microbial metabolites, including short-chain fatty acids (SCFAs), bile acids, and tryptophan metabolites, on neuroinflammation, blood-brain barrier (BBB) integrity, and amyloid-β and tau pathology. The paper highlights major microbiome signatures associated with Alzheimer's disease, detailing their metabolic pathways and inflammatory crosstalk. Dietary interventions have shown promise in modulating gut microbiota composition, potentially mitigating neurodegenerative processes. This review critically examines the influence of dietary patterns, such as the Mediterranean and Western diets, on microbiota-mediated neuroprotection. Bioactive compounds like prebiotics, omega-3 fatty acids, and polyphenols exhibit neuroprotective effects by modulating gut microbiota and reducing neuroinflammation. Furthermore, it discusses emerging microbiome-based therapeutic strategies, including probiotics, prebiotics, postbiotics, and fecal microbiota transplantation (FMT), as potential interventions for slowing Alzheimer's progression. Despite these advances, several knowledge gaps remain, including interindividual variability in microbiome responses to dietary interventions and the need for large-scale, longitudinal studies. The study proposes an integrative, precision medicine approach, incorporating microbiome science into Alzheimer's treatment paradigms. Ultimately, cognizance of the gut-brain axis at a mechanistic level could unlock novel therapeutic avenues, offering a non-invasive, diet-based strategy for managing neurodegeneration and improving cognitive health.},

The disease is characterized by a disturbed body image, restrictive eating behavior, and a lack of acknowledgment of low body weight. The underlying causes of AN remain largely unknown, and current treatment options are limited to psychotherapy and nutritional support. This paper investigates the impact of Fecal Microbiota Transplants (FMT) from patients with AN on food intake, body weight, behavior, and gut microbiota into antibiotic-treated mice. Two rounds of FMT were performed using AN and control (CO) donors. During the second round of FMT, a subset of mice received gut microbiota (GM) from a different donor type. This split-group cross-over design was chosen to demonstrate any recovery effect of FMT from a non-eating disorder state donor. The first FMT, from donors with AN, resulted in lower food intake in mice without affecting body weight. Analysis of GM showed significant differences between AN and CO mice after FMT1, before cross-over. Specific bacterial genera and families Ruminococcaceae, Lachnospiraceae, and Faecalibacterium showed different abundances in AN and CO receiving mice. Behavioral tests showed decreased locomotor activity in AN mice after FMT1. After FMT2, serum analysis revealed higher levels of appetite-influencing hormones (PYY and leptin) in mice receiving AN-GM. Overall, the results suggest that AN-GM may contribute to altered food intake and appetite regulation, which can be ameliorated with FMT from a non-eating disorder state donor potentially offering FMT as a supportive treatment for AN.},

abstract = {As an emerging contaminant, nanoplastics have evolved into a global ecological issue. Studies have shown that nanoplastics induce neurotoxicity across species, however, the causal mechanism remains unknown. This study aimed to explore the mechanism underlying the neurotoxicity caused by polystyrene nanoplastics (PS-NPs) via microbiota-gut-brain axis in immature mice, which serve as a model of infants and young children who are at higher exposure risk to NPs. The results indicated that while only a minority of PS-NPs reached the brain after exposure, they still had significant neurotoxic effects, as reflected by abnormalities in behavior, biochemical marker levels and histopathology. Proteomics and quantification analyses revealed that a proteostasis imbalance mediated by lysosomal and proteasome dysfunction in the brain is the key reason for the induced neurotoxicity. Further, we confirmed the indirect role of gut microbiota in the neurotoxicity induced by PS-NPs through 16S rDNA analyses and fecal microbiota transplantation. Crucial bacterial species such as Eubacterium coprostanoligenes potentially act as indicators for gut dysbiosis after PS-NPs exposure. Notably, we first estimated the indirect effect of gut microbiota on neurotoxicity attributed to PS-NPs in immature mice as 39.20% by high-dimensional mediation analysis. Trehalose was identified as a mediator connecting the gut microbiota and the brain, and the crucial role of trehalose supplementation was highlighted in remodeling the brain proteostasis to alleviate the neurotoxicity in immature mice. These findings are expected to contribute to a deeper understanding of the risk assessment and health protection of the nervous system from exposure to PS-NPs early in life.},

abstract = {BACKGROUND: Severe alcohol-associated hepatitis (sAH) has a high short-term mortality, with limited treatment options. Fecal microbiota transplantation (FMT) has shown benefits in small, uncontrolled studies.

AIM: Perform a systematic review and meta-analysis to provide updated evidence on the efficacy and safety of FMT in sAH patients.

METHOD: Electronic databases were searched till 4 December 2023 for studies comparing FMT with standard of care (SOC) in sAH patients. Sensitivity analysis (leave-one-out method) and subgroup analyses were performed. Pooled risk ratio (RR) was used to compare the survival outcomes.

RESULTS: Eight studies with 444 patients (FMT: 218; SOC: 226) met the eligibility criteria and were included in this meta-analysis. The 28- and 90-day survival range was higher in the FMT group (75-100% and 53-87%) compared to the SOC group (48-80% and 25-56%). The random-effects model showed a statistically significant increase in survival in the FMT arm at 28 days [RR (95% confidence interval) 2.30 (1.24-4.28), P = 0.01] and 90 days [2.53 (1.34-4.77), P < 0.001]. However, there was no statistically significant change in survival at the 6-month [1.89 (0.89-4.05), P = 0.10] and the 12-month time [1.86 (0.68-5.08), P = 0.23]. Sensitivity analysis showed no major changes in the overall effect sizes, and subgroup analysis showed that the survival benefit was restricted only to the retrospective studies. No serious treatment-related adverse events were reported.

CONCLUSION: FMT is a safe and efficacious treatment option that improves short-term survival in sAH patients, without major adverse events. A multicentre randomized controlled trial with an adequate sample size is required to confirm these findings.},

Leflunomide (Lef) can suppress the growth of several tumor and mitigate cardiac remodeling in mice. However, the role of Lef in αPD1-induced cardiotoxicity remains unclear. Here, we report that Lef treatment inhibits αPD1-related cardiotoxicity without compromising the efficacy of αPD1-mediated immunotherapy. Lef changes community structure of gut microbiota in αPD1-treated melanoma-bearing mice. Moreover, mice receiving microbiota transplants from Lef+αPD1-treated melanoma-bearing mice have better cardiac function compared to mice receiving transplants from αPD1-treated mice. Mechanistically, we analyze metabolomics and identify indole-3-propionic acid (IPA), which protects cardiac dysfunction in αPD1-treated mice. IPA can directly bind to the aryl hydrocarbon receptor and promote phosphoinositide 3-kinase expression, thus curtailing the cardiomyocyte response to immune injury. Our findings reveal that Lef mitigates αPD1-induced cardiac toxicity in melanoma-bearing mice through modulation of the microbiota-IPA-heart axis.},

Thus, our objective was to investigate and verify the effects of VD3 on glucose metabolism in prediabetes, as well as to elucidate the underlying mechanisms. In this study, different concentrations of VD3 were intraperitoneally administered to prediabetic mice induced by high fat diet for 16 weeks. Biochemical analyses, oral glucose tolerance test, 16S rRNA and untargeted metabolomics were used, the mechanism was explored. Then, fecal suspensions collected from the above donors were transplanted into KKay mice for 6 weeks, and the relevant indicators were measured. The results showed that VD3 intervention alleviated glucose metabolism in KKay mice. It increased the protein expression of colon tight junction proteins, alleviated metabolic endotoxemia and inflammation, so that reduced tumor necrosis factor alpha (TNFα) induced toll-like receptor 4/nuclear factor kappa-B (TLR4/NFκB) and improvement of phosphatidylinositol 3-kinase/protein kinase B (PI3K/AKT) insulin signaling pathway. VD3 affected the structure of gut microbiota and metabolites, and functional prediction analysis suggested that VD3 may affect carbohydrate. Besides, the effect of VD3 could be delivered by fecal microbiota transplantation (FMT). Consequently, VD3 ameliorate glucose metabolism by modulating gut microbiota and metabolites in KKay mice, and this ability could be transferred by FMT.},

abstract = {Endothelial cell senescence is a key driver of cardiovascular aging, yet little is known about the mechanisms by which it is induced in vivo. Here we show that the gut bacterial metabolite phenylacetic acid (PAA) and its byproduct, phenylacetylglutamine (PAGln), are elevated in aged humans and mice. Metagenomic analyses reveal an age-related increase in PAA-producing microbial pathways, positively linked to the bacterium Clostridium sp. ASF356 (Clos). We demonstrate that colonization of young mice with Clos increases blood PAA levels and induces endothelial senescence and angiogenic incompetence. Mechanistically, we find that PAA triggers senescence through mitochondrial H2O2 production, exacerbating the senescence-associated secretory phenotype. By contrast, we demonstrate that fecal acetate levels are reduced with age, compromising its function as a Sirt1-dependent senomorphic, regulating proinflammatory secretion and redox homeostasis. These findings define PAA as a mediator of gut-vascular crosstalk in aging and identify sodium acetate as a potential microbiome-based senotherapy to promote healthy aging.},

This study focused on quality assurance of an enteric-coated capsule formulation of FMT as a medicinal product by evaluating bacterial composition, diversity and viability through manufacturing steps and upon product storage at a range of temperatures. Faecal donations from pre-screened healthy individuals (n = 5) were processed according to a published protocol into one or more treatments; 5 capsules = 1 treatment dose/patient. Culture-independent next-generation 16S rRNA gene sequencing was used to speciate and quantify bacteria using a live-dead cell separation method to discriminate the viable cell load. Species diversity in donor stools aligned with other healthy gut microbiome and remained unchanged through the manufacturing process and after storage at -80 °C for 36 weeks. While diversity indices were consistent, a notable difference was observed between viable and total microbiome, particularly in species richness, which decreased when non-viable or compromised cells were excluded from analysis. Anaerobic species exhibited minimal viability loss despite processing in an aerobic environment. Furthermore, capsules were stable with storage at -20 °C and 2-8 °C, with no significant reduction of total live bacterial load after 24 weeks. In summary, 'live-dead' culture-independent analysis was used to characterise the viable faecal microbiome, which retained a diversity of bacterial species, including anaerobes, through manufacture and after storage in capsules for up to 36 weeks. These data support the comparable effectiveness of lyophilised encapsulated FMT to other formulations and delivery methods.},

abstract = {Bazi Bushen Capsule (BZBS), a traditional Chinese medicine formulation composed of multiple bioactive herbal components, has been validated in multicenter randomized double-blind controlled trials for its potent anti-aging properties. Previous studies from our group have demonstrated that BZBS effectively restores gut microbiota homeostasis and attenuates the impairment of intestinal barrier function, thereby ameliorating age-related cognitive decline. However, the specific molecular mechanisms by which BZBS modulates key microbial-metabolite networks to delay brain aging remain poorly understood and warrant further investigation.

AIM OF THE STUDY: This study aims to elucidate the key microbiota-metabolite networks through which BZBS improves cognitive function and delays brain aging in senescence-accelerated mouse-prone 8 (SAMP8) mice.

MATERIALS AND METHODS: Eight-week-old male SAMP8 mice were used as experimental models, randomly divided into Model, BZ-low (0.5 g/kg/d BZBS), BZ-high (1 g/kg/d BZBS), and RAPA (2 mg/kg/d rapamycin) groups. Senescence-accelerated mouse resistant 1 (SAMR1) mice served as the control group. Cognitive function was assessed using the Barnes Maze test and the three-chamber social test. The structural damage and pathological changes in the brain tissue were evaluated through transcranial Doppler, micro-computed tomography, Nissl staining, and Western blot analysis. Next, the intestinal barrier function was detected by hematoxylin-eosin (HE) staining, periodic acid-Schiff (PAS) staining, and immunofluorescence (IF) staining. Characteristic bacteria were identified by 16S rRNA sequencing, and metabolomic profiling was performed using non-targeted metabolomics. Akkermansia muciniphila (Akk) was cultured, and fecal microbiota transplantation (FMT) was employed to evaluate its contribution to intestinal barrier function.

RESULTS: The study revealed that BZBS therapy not only enhances cognitive capabilities but also restores the intestinal barrier function. Akk was identified as a key regulatory agent mediating the therapeutic effects of BZBS. BZBS administration significantly increased the abundance of Akk and modulated its metabolite profile, particularly components associated with spermidine, thereby reinforcing the intestinal barrier and mitigating age-related cognitive decline. Furthermore, this study demonstrated that Akk, administered via fecal microbiota transplantation, alleviated dextran sulfate sodium (DSS)-induced colitis..

CONCLUSION: The results showed that BZBS capsule, a traditional Chinese medicine, may delay brain aging in SAMP8 mice by modulating Akk and its spermidine production.},

OBSERVATIONS: Clinical and preclinical evidence suggests that microbes in the gastrointestinal tract and other anatomical locations, such as the respiratory tract, may affect carcinogenesis, development of metastases, cancer treatment response, and cancer treatment-related adverse effects. Within tumors of patients with cancer, microbes may affect response to treatment, and therapies that reduce or eliminate these microbes may improve outcomes in patients with cancer. Modulating gastrointestinal tract (gut) microbes through fecal microbiota transplant and other strategies such as dietary intervention (eg, high-fiber diet intervention) has improved outcomes in small studies of patients treated with cancer immunotherapy. In contrast, disruption of the gut microbiota by receipt of broad-spectrum antibiotics prior to treatment with cancer immunotherapy has been associated with poorer overall survival and higher rates of adverse effects in patients treated with immune checkpoint blockade for solid tumors and also with chimeric antigen receptor T-cell therapy for hematologic malignancies.

CONCLUSIONS AND RELEVANCE: Microbes in the gut and other locations in the body may influence the development and progression of cancer and may affect the response to adverse effects from cancer therapy. Future therapies targeting microbes in the gut and other locations in the body could potentially improve outcomes in patients with cancer.},

This review delineates taxonomic alterations in central precocious puberty (CPP) and obesity-related subtypes, including Streptococcus enrichment and Alistipes depletion, alongside functional shifts in microbial metabolite production. Mechanistic insights highlight microbiota-driven modulation of the hypothalamic-pituitary-gonadal (HPG) axis, leptin/insulin dynamics, and epigenetic regulation. Emerging interventions-probiotics, fecal microbiota transplantation (FMT), and dietary modifications-demonstrate efficacy in preclinical models and early clinical studies for delaying puberty onset and restoring hormonal balance.

abstract = {This study delves into the mechanism of total flavone of Abelmoschus manihot(TFA) in treating ulcerative colitis(UC) and depression via inhibiting M1 polarization of macrophages and reshaping intestinal flora and glycerolphospholipid metabolism. The study established a mouse model of UC and depression induced by chronic restraint stress(CRS) and dextran sulfate sodium(DSS). The fecal microbiota transplantation(FMT) experiment after TFA intervention was conducted. Mice in the FMT donor group were modeled and treated, and fecal samples were taken to prepare the bacterial solution. Mice in the FMT receptor group were treated with antibiotic intervention, and then administered bacterial solution by gavage from mice in the donor group, followed by UC depression modeling. After the experiment, behavioral tests were conducted to evaluate depressive-like behaviors by measuring the levels of 5-hydroxytryptamine(5-HT) and brain-derived neurotrophic factor(BDNF) in the hippocampus of mice. The levels of tumor necrosis factor-α(TNF-α),interleukin-6(IL-6),and interleukin-1β(IL-1β)in the brain and colon tissue of mice were also measured, and the polarization status of macrophages was evaluated by measuring the mRNA levels of CD86 and CD206. 16S ribosomal RNA(16S rRNA) sequencing technology was used to analyze changes in the intestinal flora of mice. Wide target lipidomics was used to detect serum lipid metabolite levels in mice after FMT,and correlation analysis was conducted between lipids and differential intestinal flora significantly regulated by TFA. In vitro experiments, representative glycerophospholipid metabolites and glycerophospholipid inhibitors were used to intervene in Raw264.7 macrophages, and the mRNA levels of TNF-α,IL-6,IL-1β,CD86,and CD206 were detected. The results showed that TFA and FMT after intervention could significantly improve depressive-like behavior and intestinal inflammation in mice with UC and depression, significantly downregulate pro-inflammatory cytokines and CD86 mRNA expression in brain and colon tissue, inhibiting M1 polarization of macrophages, and significantly upregulate CD206 mRNA expression, promoting M2 polarization of macrophages. In addition, the high-dose group had a more significant effect. After TFA intervention, FMT significantly corrected the metabolic disorder of glycerophospholipids in mice with UC and depression, and there was a significant correlation between differential intestinal flora and glycerophospholipids. In vitro experiments showed that glycerophospholipid metabolites, especially lysophosphatidylcholine(LPC),significantly upregulated pro-inflammatory cytokines and CD86 mRNA expression, promote M1 polarization of macrophages, while glycerophospholipid inhibitors had the opposite effect. The results indicate that TFA effectively treats depression and UC by correcting intestinal flora dysbiosis and reshaping glycerophospholipid metabolism, thereby inhibiting M1 polarization of macrophages.},

abstract = {BACKGROUND: Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a complex disorder characterized by persistent fatigue and cognitive impairments, with emerging evidence highlighting the role of gut health in its pathophysiology. The main objective of this review was to synthesize qualitative and quantitative data from research examining the gut microbiota composition, inflammatory markers, and therapeutic outcomes of interventions targeting the microbiome in the context of ME/CFS.

METHODS: The data collection involved a detailed search of peer-reviewed English literature from January 1995 to January 2025, focusing on studies related to the microbiome and ME/CFS. This comprehensive search utilized databases such as PubMed, Scopus, and Web of Science, with keywords including "ME/CFS," "Gut-Brain Axis," "Gut Health," "Intestinal Dysbiosis," "Microbiome Dysbiosis," "Pathophysiology," and "Therapeutic Approaches." Where possible, insights from clinical trials and observational studies were included to enrich the findings. A narrative synthesis method was also employed to effectively organize and present these findings.

RESULTS: The study found notable changes in the gut microbiota diversity and composition in ME/CFS patients, contributing to systemic inflammation and worsening cognitive and physical impairments. As a result, various microbiome interventions like probiotics, prebiotics, specific diets, supplements, fecal microbiota transplantation, pharmacological interventions, improved sleep, and moderate exercise training are potential therapeutic strategies that merit further exploration.

CONCLUSIONS: Interventions focusing on the gut-brain axis may help reduce neuropsychiatric symptoms in ME/CFS by utilizing the benefits of the microbiome. Therefore, identifying beneficial microbiome elements and incorporating their assessments into clinical practice can enhance patient care through personalized treatments. Due to the complexity of ME/CFS, which involves genetic, environmental, and microbial factors, a multidisciplinary approach is also necessary.

abstract = {Nephropathy II Decoction (NED) is a widely used Chinese medicinal formulation for managing chronic kidney disease (CKD). Despite its extensive application, the precise mechanisms underlying its therapeutic effects remain poorly understood. This study aims to elucidate the role of NED in attenuating renal fibrosis and to explore its impact on the gut-kidney axis. The principal constituents of NED were analyzed using ultra-performance LC-tandem mass spectrometry (UPLC-MS/MS). A bilateral renal ischemia-reperfusion injury (bIRI) model was employed to induce fibrosis. RT-qPCR was utilized to assess the expression of mRNA related to the toll-like receptor 4 (TLR4) and myeloid differentiation factor 88 (MyD88) and nuclear factor-κB (NF-κB) signaling pathway. Western blotting analysis was performed to identify changes in renal fibrosis markers, TLR4/MyD88/NF-κB pathway proteins, and the colon proteins ZO-1 and Occludin-1. Serum levels of uremic toxins were quantified using enzyme-linked immunosorbent assay (ELISA), and 16S ribosomal RNA (rRNA) gene sequencing was conducted to explore changes in the gut microbiome of the mice. Our study demonstrated that mice in the NED group exhibited reduced serum creatinine, blood urea nitrogen, and urinary protein levels, alongside improvements in kidney damage and a decrease in renal fibrosis markers. In the bIRI group, TLR4/MyD88/NF-κB protein and mRNA levels, as well as intestinal tight junction proteins and enterogenic uremic toxins, were significantly reduced. NED treatment reversed these changes and modified the gut microbiota. Furthermore, fecal microbial transplantation (FMT) alleviated kidney damage and fibrosis in bIRI mice. In summary, NED ameliorates kidney injury and fibrosis by modulating the gut microbiota and may further attenuate fibrosis through the inhibition of TLR4 expression, thereby influencing the gut-kidney axis.},

AIM OF THE STUDY: To investigate whether the protective effect of LZD on ulcerative colitis is dependent on gut microbiota and T-cell immune homeostasis.

MATERIAL AND METHODS: The preventive effects of LZD on dextran sodium sulfate (DSS)-induced colitis mice were evaluated through the measurement of body weight, disease activity index, colon length and hematoxylin-eosin staining. Flow cytometry was used to detect the ratio of Th17/Treg cells. Pseudo sterile mice and fecal transplantation experiments were used to investigate whether the preventive effect of LZD was dependent on the gut microbiota. The alterations of gut microbiota were identified by the 16S rDNA sequencing. The content of intestinal short-chain fatty acids (SCFAs) was detected by LC-MS/MS analysis. The downstream signal pathways of SCFAs were detected by the immunoblotting.

RESULTS: LZD administration significantly alleviated weight loss and intestinal injury in DSS-induced colitis mice. LZD administration also promotes the balance of Th17/Treg cells. Moreover, LZD administration relies on gut microbiota to alleviate ulcerative colitis and regulate Th17/Treg cell balance. LZD administration significantly improves gut microbial composition in colitis mice, elevating the abundance of SCFAs producing bacterium such as lachnospiraceae_nk4a136_group and Akkermansia. LZD treatment further increases the abundance of SCFAs and promotes activation of free fatty acid activated receptor 2 (FFAR2).

CONCLUSION: LZD administration promotes Th17/Treg cell balance in a gut microbiota-SCFAs dependent manner, which in turn ameliorates ulcerative colitis.},

First, we discuss how different social determinants of health, such as socioeconomic status, diet, environmental chemicals, migration, ecological conditions, and seasonal changes may influence gut microbiome composition, diversity, and functionality, along with epigenetic alterations and thereby affect social behavior. Next, we consider how gut microbiome-derived metabolites, diet, probiotics, and fecal microbiome transplantation may reduce impairments in social interactions through the adjustment of epigenetic aberrations (e.g., DNA methylation, histone modifications, and microRNAs expression) which may suppress or increase gene expression patterns. Finally, we present the potential benefits and unresolved challenges with the use of gut microbiome-targeted therapeutics in reducing social deficits.},

Melatonin, as a multifunctional molecule, has the potential to regulate intestinal homeostasis and skin function. The study further explored the potential mechanism of melatonin in ameliorating skin barrier damage from the perspective of the association between intestinal microbiota and gut-skin axis in aging mice. We established a natural aging-induced skin barrier damage mouse model with or without melatonin supplementation and fecal microbiota transplantation (FMT) to clarify the crucial role of intestinal microbiota-mediated gut-skin axis in melatonin improving skin barrier damage. Furthermore, lipopolysaccharide (LPS)-treated mice and human keratinocytes cells (HaCaT) explored the modulation mechanism of melatonin. Our results suggested that aging induced skin barrier damage, including skin microbiota disorder and epidermal barrier structure disruption, and intestinal dysbiosis. Similarly, FMT from aging mice and LPS treatment rebuild the aging-like skin barrier damage. Whereas, melatonin or resatorvid (TAK242, the antagonist of LPS) supplementation restored all consequence in aging and LPS-treated mice. In vitro, melatonin restored LPS-induced skin barrier proteins deficiency in HaCaT via decreasing the expression level of TLR4 and MyD88 and increasing the content of p-ERK, p-GSK-3β and β-catenin proteins, while the improving effects was mimicked by pretreatment with a TLR4 antagonist but were blocked by GSK-3β agonists. Our study revealed that melatonin-mediated intestinal microbiota homeostasis suppresses LPS escape to restore the skin barrier function, including skin dysbiosis and epidermal structural disruption via LPS/TLR4/MyD88/ERK/GSK-3β/β-catenin loop, further improving skin aging in mice.},

abstract = {Obesity is associated with skeletal deterioration and increased fracture risk, but the underlying mechanism is unclear. Herein, it is shown that obese gut microbiota promotes skeletal deterioration by inducing bone marrow macrophages (BMMs) senescence and grancalcin (GCA) secretion. Obese mice and those receiving obese fecal microbiota transplants exhibit increased senescent macrophages and elevated GCA expression in the bone marrow. In a study of 40 participants, it is found that obese patients are associated with higher serum GCA levels. It is further revealed that obese gut-microbiota derived lipopolysaccharides (LPS) stimulate GCA expression in senescent BMMs via activating Toll-like receptor 4 pathway. Mice with depletion of the Gca gene are resistant to the negative effects of obesity and LPS on bone. Moreover, neutralizing antibody against GCA mitigates skeletal deterioration in obese mice and LPS-induced chronic inflammation mouse model. The data suggest that the interaction between gut microbiota and the immune system contributes to obesity-associated skeletal deterioration, and targeting senescent macrophages and GCA shows potential of protecting skeletal health in obese population.},

abstract = {BACKGROUND: Autism Spectrum Disorder (ASD) is a complex neurodevelopmental condition characterized by persistent deficits in social interaction and communication. Emerging evidence suggests that alterations in the gut-brain axis play a key role in the pathophysiology of ASD, and that microbiota-targeted interventions may offer therapeutic benefits. However, no clear consensus has been reached regarding the effectiveness of these strategies in ameliorating behavioral characteristics. This systematic review and meta-analysis (PROSPERO registration ID: CRD42023494067) aimed to evaluate the impact of microbiota-based interventions-including synbiotics, prebiotics, single-strain probiotics, probiotic blends, and fecal microbiota transplantation (FMT)-on behavioral outcomes in individuals with ASD, with particular emphasis on social functioning.

RESULTS: Of the 373 records initially identified, 20 studies met the inclusion criteria, comprising 16 randomized controlled trials and 4 open-label studies. The overall effect size indicated a statistically significant improvement in ASD-related behavioral symptoms following microbiota manipulation (Hedges' g = 0.47; 95 % CI: 0.30-0.64; p < 0.001; I[2] = 33.01 %), representing a small but clinically relevant effect. Heterogeneity was classified as moderate. Among the interventions, FMT and probiotic blends yielded the most substantial effects. All major limitations of the current studies were thoroughly addressed and discussed to guide future experimental designs. Additionally, we examined preclinical evidence supporting the involvement of neural, immune, and metabolic pathways in mediating the observed behavioral improvements.

CONCLUSIONS: Our findings support the potential of microbiota-based therapies as a promising and well-tolerated strategy for improving behavioral symptoms in individuals with ASD. FMT and multi-strain probiotic formulations appear particularly effective. Nevertheless, further high-quality randomized controlled trials-especially involving FMT-are urgently needed to validate these results and guide clinical implementation. Thus, these findings provide a critical foundation for future investigations seeking to refine microbiota-based interventions and uncover the underlying mechanisms through which they influence ASD-related behaviors.},

Cinnamon is a food and medicinal resource associated with lipid metabolism, but the mechanism by which its active components, cinnamic acid (CA) and cinnamaldehyde (CM), alleviate hyperlipidaemia remains unclear. Biochemical, pathological, gut microbiota, and metabolomic analyses were performed to investigate the effects of CA and CM on HFD-fed mice and the underlying mechanisms involved. Supplementation with CA and CM reduced body weight, liver, and adipose tissue accumulation in HFD-induced mice; improved glucose and lipid metabolism; and decreased inflammation and oxidative stress levels, with CM showing superior efficacy. Faecal microbiota transplantation confirmed that the therapeutic effect was closely related to core gut bacteria and metabolites. Specifically, CA and CM inhibited the growth of lipid metabolism-related genera (e.g., Turicibacter and Romboutsia) and metabolites (e.g., PC, LysoPCs, prostaglandin E2, and arachidonic acid) while promoting the growth of beneficial genera (e.g., Oscillospiraceae and Colidextribacter) and metabolites (e.g., linoleic acid, phytosphingosine, and stercobilin). Additionally, Spearman's correlation analysis revealed that serum and hepatic lipids, as well as inflammatory factors, were positively correlated with Erysipelatoclostridium, Turicibacter, Eubacterium fissicatena, Enterorhabdus, cervonoyl ethanolamide, and acetoxystachybotrydial acetate, whereas they were negatively correlated with Lachnospiraceae NK4A136, stercobilin, LysoPE (15:0/0:0), and phytosphingosine. In contrast, hepatic oxidative stress markers exhibited the opposite correlation pattern. In conclusion, CA and CM have the potential to regulate the core gut microbiota and metabolites to improve lipid metabolism and decrease related inflammation and oxidative stress levels.},

The precise mechanisms by which microcystin-LR, a potent cyanotoxin, disrupts lipid metabolism in amphibian tadpoles remain unclear. In this study, tadpoles (Pelophylax nigromaculatus) were exposed to MC-LR and fecal microbiota transplantation (FMT) experiments were performed to investigate whether or how MC-LR at environmental concentrations interfered with tadpole lipid metabolism from the perspective of the gut microbiota-gut-liver axis. Following exposure, the liver exhibited significant inflammation, hypertrophy, and fibrosis, accompanied by elevated serum lipid levels. Furthermore, the expression levels of the farnesoid X receptor (FXR), a nuclear receptor, were significantly downregulated. Molecular docking and molecular dynamics simulations indicated a strong and stable binding between FXR and MC-LR. Moreover, MC-LR suppressed liver FXR expression or activity, triggering: (1) upregulation of sterol regulatory element-binding protein 1 (SREBP1)-mediated triglyceride (TG) synthesis, (2) inhibition of free fatty acid (FFA) β-oxidation, and (3) activation of SREBP2-dependent bile acid biosynthesis. Moreover, MC-LR altered the composition of gut microbiota and specific bile acid levels (e.g., taurocholic acid and glycochenodeoxycholic acid) in the gut, thereby interfering with hepatic lipid metabolism, as evidenced by FMT-induced hepatic lipid accumulation in recipient tadpoles. These findings identify FXR as a potentially key molecular target for MC-LR and suggest that changes in bile acid levels of intestinal microbiota metabolism also may be an important pathway driving hepatic lipid dysregulation in amphibians exposed to environmental concentrations of MC-LR.},

The imbalance of intestinal microbiota not only directly promotes the development of MASLD but also further exacerbates disease progression through abnormalities in their metabolites. Various novel therapeutic strategies are being actively developed on the basis of gut-liver axis theory, including probiotic/prebiotic/synbiotic treatment, fecal microbiota transplantation, and targeted drug therapy. These strategies aim to precisely regulate microbial homeostasis and improve glucose and lipid metabolism, thereby alleviating hepatic inflammation and fibrosis and optimizing the therapeutic outcomes of patients with MASLD. In the future, as research progresses, we will further uncover the interaction mechanisms between intestinal microbiota and MASLD and continuously explore more effective treatment methods, with the goal of improving the prognosis and quality of life for MASLD patients.},

abstract = {BACKGROUND: Obesity-related cognitive decline is linked to gut microbiota dysbiosis, with emerging evidence suggesting that dietary interventions may ameliorate cognitive impairment via gut-brain axis modulation. The role of microglial cells in this process remains underexplored.

OBJECTIVE: To investigate how diet-induced changes in gut microbiota influence cognitive function in individuals with obesity and their microglial activity, and to determine the impact of specific dietary interventions.

DESIGN: This study included 96 participants with obesity who were randomised into three dietary intervention groups: Mediterranean diet (Med), alternate-day fasting (ADF) and ketogenic diet (Keto). Cognitive performance and microbiota composition were assessed pre-intervention and post-intervention. The effects of microbiota-related changes on microglial function were further evaluated in mice models through faecal transplantation and in vitro model with microbiota exosome treatment.

RESULTS: Both the Keto and ADF groups demonstrated significant weight loss, but cognitive performance improved most notably in the ADF group, in association with reduced inflammation. Diet-related microbiota composition was correlated with the cognitive outcomes in the human study. Mice models confirmed that the cognitive benefits of ADF were microbiota-dependent and linked to enhanced microglial phagocytic capacity and reduced inflammation, accompanied by changes in microglia morphology.

CONCLUSION: Fasting-induced modifications in gut microbiota contribute to cognitive improvement in individuals with obesity, with microglial cells playing a crucial mediatory role. Among the interventions, ADF most effectively enhanced microglial function and cognitive performance, suggesting its potential as a therapeutic strategy for obesity-related cognitive decline. Further studies are required to fully elucidate the underlying mechanisms.

abstract = {BACKGROUND: Camellia japonica radix (CJR), derived from the root of Camellia japonica L., has the potential to function as an herbal tea substitute for the prevention and intervention of metabolic dysfunction-associated steatotic liver disease (MASLD). It can provide systemic therapeutic benefits, boast a favorable safety profile, facilitate convenient consumption, and support long-term applicability. Despite its potential, research on CJR remains limited.

PURPOSE: The aim of this study aims is to elucidate the therapeutic mechanisms of CJR in MASLD, thereby providing evidence to support its clinical application.

METHODS: The therapeutic effects of CJR were evaluated using a water-supplementation model in MASLD mice. Integrated microbiome, transcriptome, proteome, and metabolome analyses were employed to comprehensively explore the mechanisms involved. A drug-target pull-down assay was performed to identify specific protein targets of small molecule metabolites in vitro. Fecal microbiota transplantation in antibiotic-treated ABX mice was conducted to confirm the critical role of gut microbiota and its metabolites. Furthermore, customized medicated feed supplemented with linoleic acid was used to explore the intervention effect of its metabolite, 9(S)-HpODE, as well as to evaluate its dietary intervention potential.

RESULTS: This present study explicitly elucidates the efficacy of CJR extract in alleviating hepatic inflammation and steatosis in a MASLD model mice, with its pharmacological mechanism associated with gut microbiota, linoleic acid metabolism, and GPX4-mediated ferroptosis. Notably, 9(S)-HpODE was discovered to be a key metabolite of linoleic acid, which could target both KEAP1 and SLC7A11, bidirectionally regulating GPX4-mediated ferroptosis, while acting as a signaling molecule at low doses to induce redox adaptation via oxidative preconditioning, thus ameliorating oxidative stress in MASLD.

CONCLUSION: Our findings indicate that both CJR and linoleic acid exhibit significant potential as dietary interventions for the management of MASLD, offering promising avenues for future research and clinical application.},

Emerging evidence implicates the gut microbiota in regulating inflammatory responses, metabolic pathways, and immune homeostasis. This review synthesizes current evidence on gut microbiota dysbiosis in psoriasis and evaluates the therapeutic potential of probiotics and fecal microbiota transplantation (FMT) in disease management. Method: Following PRISMA guidelines, we systematically reviewed studies investigating gut microbiome profiles in psoriasis through the MEDLINE, EMBASE, and Web of Science databases (January 2015-December 2024). Included studies utilized 16S rRNA gene sequencing or metagenomic analyses for microbial characterization. Results: Comparative analyses revealed distinct gut microbiota patterns in psoriasis patients compared with healthy controls, although specific microbial signatures exhibited inconsistencies across studies. Notably, interventions modulating gut microbiota composition-particularly probiotic supplementation-demonstrated measurable improvements in psoriasis severity scores and inflammatory markers. Conclusions: Gut microbiome modulation represents a promising therapeutic strategy for psoriasis; however, current evidence highlights the need for standardized microbial analysis methodologies and larger longitudinal studies to establish causality. Future research should prioritize the functional characterization of microbiota-host interactions to optimize therapeutic applications.},

abstract = {The gut microbiome, a complex community of microorganisms residing in the intestinal tract, plays a dual role in colorectal cancer (CRC) development, acting both as a contributing risk factor and as a protective element. This review explores the mechanisms by which gut microbiota contribute to CRC, emphasizing inflammation, oxidative stress, immune evasion, and the production of genotoxins and microbial metabolites. Fusobacterium nucleatum, Escherichia coli (pks+), and Bacteroides fragilis promote tumorigenesis by inducing chronic inflammation, generating reactive oxygen species, and producing virulence factors that damage host DNA. These microorganisms can also evade the antitumor immune response by suppressing cytotoxic T cell activity and increasing regulatory T cell populations. Additionally, microbial-derived metabolites such as secondary bile acids and trimethylamine-N-oxide (TMAO) have been linked to carcinogenic processes. Conversely, protective microbiota, including Lactobacillus, Bifidobacterium, and Faecalibacterium prausnitzii, contribute to intestinal homeostasis by producing short-chain fatty acids (SCFAs) like butyrate, which exhibit anti-inflammatory and anti-carcinogenic properties. These beneficial microbes enhance gut barrier integrity, modulate immune responses, and inhibit tumor cell proliferation. Understanding the dynamic interplay between pathogenic and protective microbiota is essential for developing microbiome-based interventions, such as probiotics, prebiotics, and fecal microbiota transplantation, to prevent or treat CRC. Future research should focus on identifying microbial biomarkers for early CRC detection and exploring personalized microbiome-targeted therapies. A deeper understanding of host-microbiota interactions may lead to innovative strategies for CRC management and improved patient outcomes.},

abstract = {BACKGROUND: Vitiligo, a depigmenting autoimmune skin disease characterized by melanocyte dysfunction or death, is known to be associated with an imbalance in gut microbiota. Oxidative stress plays a critical role in the pathogenesis of vitiligo. However, the complex promising interaction between abnormal accumulation of reactive oxygen species (ROS) in the skin and gut microbiota has remained unclear.

RESULTS: Here, we compared transcriptome data of vitiligo lesions and normal skin and identified a high expression of oxidative stress-related genes in vitiligo lesions. We also established a vitiligo mouse model and found that the presence of gut microbiota influenced the expression of ROS-related genes. Depletion of gut microbiota reduced abnormal ROS accumulation and mitochondrial abnormalities in melanocytes, significantly improving depigmentation. Our findings from manipulating gut microbiota through cohousing, fecal microbiota transplantation (FMT), and probiotic supplementation showed that transferring gut microbiota from mice with severe vitiligo-like phenotypes exacerbated skin depigmentation while probiotics inhibited its progression. Targeted metabolomics of fecal, serum, and skin tissues revealed gut microbiota-dependent accumulation of hippuric acid, mediating excessive ROS in the skin. Elevated serum hippuric acid levels were also confirmed in vitiligo patients. Additionally, a microbiota-dependent increase in intestinal permeability in vitiligo mice mediated elevated hippuric acid levels, and we found that hippuric acid could directly bind to ROS-related proteins (NOS2 and MAPK14).

CONCLUSIONS: Our results suggested the important role of gut microbiota in regulating vitiligo phenotypes and oxidative stress. We identified hippuric acid, a gut microbiota-host co-metabolite, as a critical mediator of oxidative stress in vitiligo skin and its binding targets (NOS2 and MAPK14), resulting in oxidative stress. Validation in a small human cohort suggested that hippuric acid could serve as a novel diagnostic biomarker and therapeutic target for vitiligo. These findings provided new insights into how gut microbiota regulates skin oxidative stress in vitiligo and suggested potential treatment strategies for the disease. Video Abstract.},

abstract = {Pullorum disease, caused by Salmonella pullorum (S. pullorum), is a highly contagious illness affecting the poultry industry. Emerging evidence suggests that Artemisia argyit essential oil can influence the composition of gut microbes in the host, thereby promoting overall health. However, the specific mechanisms by which Artemisia argyit essential oil modulates gut microbiota to combat S. pullorum infection remains unclear. This study explored the effectiveness of various doses of Artemisia argyit essential oil in preventing S. pullorum infection in chicks. Our findings indicate that consuming this essential oil can mitigate the intestinal mucosal barrier damage and excessive inflammatory response caused by S. pullorum, as well as reverse the weight loss seen in infected chicks. Additionally, chicks that received faecal microbiota transplantation (FMT) from the gut microbiota of Artemisia argyit essential oil donors exhibited notable recovery from S. pullorum infections. This suggests that the observed protection may be linked to the modulation of gut microbiota. Furthermore, 16S rRNA sequencing revealed an increased abundance of Lactobacillus reuteri (L. reuteri), which along with the activation of Wnt/β-catenin pathways, played critical roles in the enhanced health of S. pullorum-infected chicks treated with Artemisia argyit essential oil. In summary, these findings highlight that the dietary inclusion of Artemisia argyit essential oil promotes the intestinal enrichment of L. reuteri, offering a promising strategy for the treatment and prevention of pullorum disease in chicks.},

While collections of human gut bacteria have been published, few strains are accessible to the scientific community. We have therefore created a publicly available collection of bacterial strains isolated from the human gut. The Human intestinal Bacteria Collection (HiBC) (https://www.hibc.rwth-aachen.de) contains 340 strains representing 198 species within 29 families and 7 phyla, of which 29 previously unknown species are taxonomically described and named. These included two butyrate-producing species of Faecalibacterium and new dominant species associated with health and inflammatory bowel disease, Ruminococcoides intestinale and Blautia intestinihominis, respectively. Plasmids were prolific within the HiBC isolates, with almost half (46%) of strains containing plasmids, with a maximum of six within a strain. This included a broadly occurring plasmid (pBAC) that exists in three diverse forms across Bacteroidales species. Megaplasmids were identified within two strains, the pMMCAT megaplasmid is globally present within multiple Bacteroidales species. This collection of easily searchable and publicly available gut bacterial isolates will facilitate functional studies of the gut microbiome.},

Mori through hot-water extraction, ethanol precipitation, and chromatographic purification. Structural analysis revealed that FPA1-1 was a rhamnogalacturonan-I (RG-I)-rich mixed pectin with a branching degree of 48.42 %. In vivo experiments, FPA1-1 (400 mg/kg) effectively shortened the oestrous cycle, reduced follicle stimulating hormone (FSH) level, promoted synthesis and secretion of estradiol hormone (E2) and luteinizing hormone (LH), suppressed serum interleukin-1β (IL-1β), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) levels and improved antioxidant capacity in premature ovarian failure (POF) mice. Moreover, FPA1-1 modulated gut dysbiosis of POF mice by decreasing Firmicutes/ Bacteroidetes ratio and Desulfobacterota abundance at phylum level, enriching Bacteroides, Prevotellaceae, Parabacteroides, Alloprevotella, and Muribaculaceae abundance and inhibiting Desulfovibrionaceae proliferation. FPA1-1 treatment increased short-chain fatty acids (SCFAs) level. Antibiotic cocktail treatment and fecal microbiota transplantation (FMT) experiments confirmed that FPA1-1 ameliorates the ovarian function through altering the gut microbiota composition.

Gut microbiota plays a crucial role in life activities and hypoxia adaptation. We transplanted the gut microbiota from small mammals, plateau zokors (Myospalax baileyi), from the Qinghai-Tibetan plateau (3,500 m) to Sprague-Dawley (SD) rats housed in a hypobaric chamber (equivalent to 6,000 m altitude) for 30 days. The results showed that microbiota transplantation significantly reshaped the gut microbiota structure of the rats, notably increasing the abundance of short-chain fatty acid-producing bacteria Lachnospiraceae and Prevotellaceae, alleviating hypoxia and acidosis, reducing pulmonary hypertension and right ventricular hypertrophy, increasing the production of anti-inflammatory substances like indole-3-lactic acid, and reducing the generation of pro-inflammatory substances, such as histamine and uric acid. It also decreased the expression of inflammatory genes like lgE, TNFα, and IFN-γ in the lung. Fecal microbiota transplantation from plateau-specific species to low-altitude SD rats effectively altered metabolism, changed gene expression, decreased pulmonary artery pressure, and enhanced plateau adaptability. This study demonstrates the potential effectiveness of treating hypoxic pulmonary hypertension through microbiota transplantation and offers insights into improving hypoxia adaptation.

IMPORTANCE: We report the beneficial effects of FMT on respiratory capacity, lung metabolism, and lung gene expression in SD rats under hypoxic conditions. We revealed the inhibitory effects of gut microbiota on lung mast cells and histamine expression under hypoxic conditions. The study demonstrated the potential effectiveness of treating HPH through FMT and offers insights into improving hypoxia adaptation.},

abstract = {The modulation of gut microbiota presents promising therapeutic possibilities for various health conditions, ranging from gastrointestinal infections to neurodegenerative and mental health disorders. Among the available interventions, gut microbiota modulators (GMMs) such as probiotics and prebiotics have demonstrated significant potential in infection prevention and neuroprotection. Despite these encouraging findings, the clinical application of GMMs remains challenging due to safety concerns and inconsistent effectiveness across diverse patient populations. These factors create substantial barriers to the widespread adoption of microbiota-based therapies in clinical practice. To overcome these challenges and fully leverage the therapeutic potential of microbiota modulation, this review explores the feasibility of repurposing GMMs for managing multiple health disorders. A broad spectrum of microbiota-targeted strategies is examined, including dietary modifications, fecal microbiota transplantation, bacteriophage therapy, microbiome engineering, and immune system modulation. A particularly innovative approach involves integrating GMMs with pharmaceutical delivery systems to enhance therapeutic efficacy while mitigating potential adverse effects. This integrative strategy underscores the pivotal role of the gut microbiome in health and disease, supporting the development of precision medicine tailored to individual patient needs. By combining GMMs with targeted delivery mechanisms, this approach not only improves treatment effectiveness but also addresses critical concerns regarding safety and patient variability. Furthermore, this review outlines future research directions within the rapidly evolving field of microbiota modulation, emphasizing the necessity of comprehensive clinical trials and long-term safety evaluations. By critically assessing both the challenges and opportunities associated with microbiota-based interventions, this study provides a strategic framework for translating experimental research into viable clinical applications. A holistic approach to gut microbiota modulation has the potential to redefine treatment paradigms, offering personalized therapeutic strategies for a wide range of disorders and advancing the broader field of precision medicine.},

However, most existing nutrition databases are Western-centric, lacking comprehensive dietary information for non-Western populations, including Koreans. This limitation hinders the accuracy of in silico gut microbiome analyses and microbiome-disease associations. We developed the Korean Nutrition Model (KNM) to enhance in silico microbiome analyses by incorporating detailed macronutrient and micronutrient compositions reflective of Korean dietary patterns. KNM was constructed using a decision algorithm that integrates data from the Ministry of Food and Drug Safety and FooDB. Comparative analysis with the European Nutrition Model revealed significant differences in carbohydrate and vitamin compositions, which in turn influenced microbial growth rates and metabolic fluxes in in silico simulations. We further evaluated gut microbiota differences between Korean and European cohorts, including healthy individuals and inflammatory bowel disease patients. Our findings demonstrate that using an appropriate, population-specific nutrition model significantly improves microbiome analyses, reducing the risk of false associations. This study underscores the importance of regionally tailored dietary models and provides a framework for enhancing global dietary models to facilitate precision nutrition and microbiome-based disease interventions.},

abstract = {OBJECTIVE: Anorexia nervosa (AN) is a complex psychiatric disorder characterized by persistent dieting and reduced food intake, leading to significantly low body weight. Dysbiosis in the gut microbiome of patients with AN has been suggested to contribute to the pathogenesis. Here, we used fecal microbiota transplantation (FMT) in the activity-based anorexia (ABA) rat model to investigate the impact of AN-associated gut microbiota on disease-related outcomes.

METHOD: We validated the FMT in 12 Wistar rats by depleting the gut microbiome with antibiotics and transplanting two donors' fecal samples. We then transplanted fecal samples from four patients with AN or four healthy controls in 48 rats just before the ABA model exposure and included an antibiotic-only control group. During ABA, the rats had access to a running wheel and only 1.5 h access to chow for 7 days. We monitored body weight, body temperature, food intake, wheel revolutions, and gut microbiome biodiversity and composition.

RESULTS: The antibiotic treatment significantly depleted the rats' gut microbiome and subsequent transplantation made the rats' microbiome more similar to the donors' microbiome. The antibiotic-only group showed reduced survival, as well as lower body weight and temperature during ABA. Transplanted microbiota from patients with AN and healthy controls improved outcomes in the ABA model.

DISCUSSION: We do not find evidence that the microbiome of patients with AN differentially contributes to anorexia-like phenotypes based upon partial microbiome transplantation. However, the presence of a microbiome impacts the outcome of the ABA model.},

Probiotics are live, non-pathogenic microorganisms that benefit the host by regulating the gut microbiome. This review aims to study the effect of probiotics and ketogenic diets on gut microbiota and their potential as a therapy for epilepsy. We conducted a systematic search of the databases PubMed, Scopus, Embase, and the Web of Science for pertinent studies that have been published. Our search methodology was meticulously structured to be exhaustive, integrating targeted keywords and Boolean operators to guarantee the acquisition of all potentially pertinent articles. Probiotics interact with the gut microbiome, balance its composition, and influence the gut-brain axis. Moreover, they reduce neuroinflammation and oxidative stress. The ketogenic diet (KD) affects gut bacteria, influencing neurotransmitter levels and short-chain fatty acids (SCFAs), which play a role in the gut-brain axis. Studies have shown the positive effects of various probiotics in animal models of epilepsy. They demonstrate improvements in seizure activity, anxiety, and neuroinflammation. In human studies, probiotics reduced seizure frequency and enhanced quality of life in patients with drug-resistant epilepsy. We believe using probiotics or dietary interventions like KD could be a promising therapeutic strategy for managing epilepsy. This could reduce seizure frequency and make life better for patients with epilepsy.},

abstract = {Obesity is associated with alterations in the gut microbiome that may contribute to metabolic and mental health disturbances. Fecal microbiota transplantation (FMT) from humans to mice is a model proposed to study human microbiota-associated disorders. In this study, we investigated whether gut microbiota from human donors with obesity could affect behavior and metabolomic profiles of mice. Stools from donors with obesity and from lean donors were inoculated to antibiotic-pretreated mice fed a standard low-fat diet throughout the experiment. Obese-recipient mice exhibited a lower bacterial alpha-diversity and limited changes in specific taxa (e.g., an increase in Eubacterium) but were similar to lean-recipient mice in terms of dietary intake, body weight, fat mass, anxiety/depression-like behavior and glucose homeostasis. Non-targeted LC-MS metabolomic analysis revealed no change in the portal and cava serum samples. However, 1-methylnicotinamide, indole-3-acetic acid (I3A) and methyllysine were increased in the cecal content of obese-recipient compared to lean-recipient mice. Microbial metabolites derived from amino acids were positively correlated with Eubacterium. These results indicate that FMT from donors with obesity to mice fed chow diet (low in lipids) leads to minor but persistent change in intestinal microbial-derived metabolites, without recapitulating the metabolic and behavioral alterations of obesity.},

In this report, we aimed to investigate the effect of yFMT on the working memory of aged recipient rats performing delayed match-to-position (DMTP) tasks and the associated cellular and molecular mechanisms. The results revealed that yFMT mitigated the decline in DMTP task performance of aged recipients. This improvement was associated with a reshaped gut microbiota and increased levels of brain-derived neurotrophic factor, N-methyl-D-aspartate receptor subunit 1, and synaptophysin, enhancing synaptic formation and transmission. The remodeling of the gut microbiome influenced peripheral circulation and the hippocampus and medial prefrontal cortex by regulating the Th17/Treg ratio and microglial polarization. Ultimately, interleukin-4 and interleukin-17 emerged as potential key molecules driving the beneficial effects of FMT. These observations provide new insights into the gutbrain axis, emphasizing the connection between the gut and brain through the circulation system, and suggest an immunological mechanism that may help reverse age-related declines in the gut microbiota.},

This study investigates the therapeutic potential of black wolfberry polysaccharides (LRP) and anthocyanins (LRA) in treating ulcerative colitis, a chronic inflammatory bowel disease. Using a DSS-induced mouse model of colitis, we administered varying doses of LRP and LRA and evaluated their effects on disease activity, inflammation, gut barrier function, and microbiota composition. LRP demonstrated dose-dependent efficacy, with the 200 mg/kg dose showing the most significant reduction in the disease activity index (DAI), improvement in histopathology, and restoration of tight junction protein expression. In contrast, LRA exhibited an inverted U-shaped response, with the 100 mg/kg dose being the most effective. Additionally, LRP treatment modulated cytokine levels, promoting an anti-inflammatory response, and significantly restored gut microbiota balance by increasing Muribaculaceae and Limosilactobacillus while reducing Bacteroides and Helicobacter. Fecal microbiota transplantation (FMT) experiments further confirmed that the therapeutic effects of LRP are microbiota-dependent. These findings suggest that LRP, a polysaccharide derived from black wolfberry, offers a dietary intervention for colitis through immune modulation and gut microbiota restoration.},

abstract = {BACKGROUND: The development of effective and safe dietary supplements is essential for both the prevention and management of ulcerative colitis (UC), as its pathogenesis is intricate and difficult to completely resolve. Crataegus pinnatifida, a medicinal food with a long history of use, has broad medicinal value. Recent research has revealed promising insights into the role of polysaccharide derived from Crataegus pinnatifida on modulating short-chain fatty acids (SCFAs) to alleviate UC inflammation. However, the mechanisms by which CPP regulates the intestinal microbiota and key metabolites during the antagonistic phase of UC have yet to be elucidated.

OBJECTIVE: This research elucidated the protective role of CPP in relation to UC, highlighted the mechanisms through which CPP operates, particularly regarding gut microbiota and metabolism, and offered a theoretical foundation for the potential use of CPP as a dietary supplement aimed at preventing UC.

METHODS: The impact of CPP on acute UC induced by 3 % DSS in mice was examined through the evaluation of the disease activity index, measurement of colon length, and observation of body weight changes. Enzyme-linked immunosorbent assay (ELISA) was used to measure inflammatory factor levels in both serum and colon, as well as to assess oxidative stress mediators. The intestinal histological damage, mucus layer damage and the level of tight junction protein were analyzed by histopathological staining and western blot (WB). The impact of gut microbiota on CPP in colitis was evaluated using 16S rRNA sequencing, microbiota depletion experiments, and fecal microbiota transplantation (FMT) studies. The key metabolic pathways and key metabolites affected by CPP in the treatment of UC were analyzed through untargeted metabolomics sequencing, ELISA, and WB assays.

RESULTS: Prophylactic dietary supplementation with Crataegus pinnatifida polysaccharide (CPP) notably reduced the fundamental clinical manifestations of UC induced by DSS, including DAI score, reduced colon length, and weight loss, as well as inflammation and oxidative stress. CPP promoted the expression of Claudin-1, ZO-1 and Occludin and promoted mucin secretion, which contributed to the mitigation of intestinal barrier damage caused by DSS. 16S sequencing results and metabolomics results revealed that CPP intervention upregulated the relative abundance of Lactobacillus, thereby reshaping the intestinal microbiota and activate the arginine biosynthesis pathway. The results of fecal microbiota transplantation and antibiotic clearance experiments indicated that the alleviating effect of CPP on UC was dependent on the intestinal microbiota and this alleviating effect was transferred through fecal microbiota transplantation. Mechanistically, CPP indirectly promoted the expression of the rate-limiting enzyme argininosuccinate synthase 1 (ASS1) in the intestinal Arginine biosynthesis pathway by reshaping the intestinal microbiota, thereby increasing intestinal Arginine level and alleviating the inflammatory response and oxidative stress induced by DSS and intestinal barrier damage.

CONCLUSION: Our research findings demonstrate that CPP is a plant-derived polysaccharide that alleviates UC by modulating the gut microbiota and enhancing arginine biosynthesis.},

Restriction of fecal microbial diversity, abundance of pathogenic bacteria, and depletion of microbial species producing short-chain fatty acid were observed, which were associated with impaired induction of lamina propria peripheral Treg cells in Rag1w/w mice. The use of vedolizumab in Rag1w/w mice and of ustekinumab in a pRD patient were ineffective. Antibiotics ameliorated gut inflammation in Rag1w/w mice, but only bone marrow transplantation (BMT) rescued the immunopathological and microbial signatures.

METHODS: Key gut microbial metabolites, including bile acids, toll-like receptor 4, short-chain fatty acids, and bacterial toxins, contribute to HCC progression and influence immune responses through the gut-liver axis. As immune checkpoint inhibitors (ICIs) become common in HCC treatment, modulating the gut microbiota offers new strategies to enhance ICIs efficacy. However, individual differences in microbial composition introduce challenges, with some HCC patients showing resistance to ICIs.

RESULTS: This review summarizes the latest findings on the role of gut microbiota in HCC and explores emerging therapeutic approaches, including fecal microbiota transplantation, probiotics, antibiotics, and natural compounds.

CONCLUSIONS: The focus is on translating these insights into personalized medicine to optimize ICIs responses and improve HCC treatment outcomes.},

Recent studies have revealed that the gut microbiota and neuronal mitochondrial dysfunction play central roles in the pathogenesis of depression: the gut microbiota influences the course of depression through multiple pathways, including immune regulation, HPA axis modulation and neurotransmitter metabolism. Mitochondrial function serves as a key hub that mediates mood disorders through mechanisms such as defective energy metabolism, impaired neuroplasticity and amplified neuroinflammation. Notably, a bidirectional regulatory network exists between the gut microbiota and mitochondria: the flora metabolite butyrate enhances mitochondrial biosynthesis through activation of the AMPK-PGC1α pathway, whereas reactive oxygen species produced by mitochondria counteract the flora composition by altering the intestinal epithelial microenvironment. In this study, we systematically revealed the potential pathways by which the gut microbiota improves neuronal mitochondrial function by regulating neurotransmitter synthesis, mitochondrial autophagy, and oxidative stress homeostasis and proposed the integration of probiotic supplementation, dietary fiber intervention, and fecal microbial transplantation to remodel the flora-mitochondrial axis, which provides a theoretical basis for the development of novel antidepressant therapies targeting gut-brain interactions.},

abstract = {The gut microbiota crucially regulates the efficacy of immune checkpoint inhibitor (ICI) based immunotherapy, but the underlying mechanisms remain unclear at the single-cell resolution. Using single-cell RNA sequencing and subsequent validations, we investigate gut microbiota-ICI synergy by profiling the tumor microenvironment (TME) and elucidating critical cellular interactions in mouse models. Our findings reveal that intact gut microbiota combined with ICIs may synergistically increase the proportions of CD8[+], CD4[+], and γδ T cells, reduce glycolysis metabolism, and reverse exhausted CD8[+] T cells into memory/effector CD8[+] T cells, enhancing antitumor response. This synergistic effect also induces macrophage reprogramming from M2 protumor Spp1[+] tumor-associated macrophages (TAMs) to Cd74[+] TAMs, which act as antigen-presenting cells (APCs). These macrophage subtypes show a negative correlation within tumors, particularly during fecal microbiota transplantation. Depleting Spp1[+] TAMs in Spp1 conditional knockout mice boosts ICI efficacy and T cell infiltration, regardless of gut microbiota status, suggesting a potential upstream role of the gut microbiota and highlighting the crucial negative impact of Spp1[+] TAMs during macrophage reprogramming on immunotherapy outcomes. Mechanistically, we propose a γδ T cell-APC-CD8[+] T cell axis, where gut microbiota and ICIs enhance Cd40lg expression on γδ T cells, activating Cd40 overexpressing APCs (e.g., Cd74[+] TAMs) through CD40-CD40L-related NF-κB signaling and boosting CD8[+] T cell responses via CD86-CD28 interactions. These findings highlight the potential importance of γδ T cells and SPP1-related macrophage reprogramming in activating CD8[+] T cells, as well as the synergistic effect of gut microbiota and ICIs in immunotherapy through modulating the TME.},

Moreover, L-theanine upregulated the protein and mRNA expression of G-protein-coupled receptor 43 (GPR43), AKT, and phosphatidylinositide 3-kinase (PI3K). These results indicated that L-theanine alleviates UC by repairing the gut barrier via regulating the gut microbiota and SCFAs through the GPR43/PI3K/AKT signaling pathway activation. This study provides a method of preventing and treating UC via L-theanine as a safe food dietary supplement.},

However, hepatic encephalopathy (HE), which impairs neuropsychiatric function and motor control, remains the primary adverse effect of TIPS, limiting its utility. Prompt prevention and treatment of post-TIPS HE are critical, as they are strongly associated with readmission rates and poor quality of life. This review focuses on the main pathophysiological mechanisms underlying post-TIPS HE, explores advanced biomarkers and predictive tools, and discusses current management strategies and future directions to prevent or reverse HE following TIPS. These strategies include preoperative patient assessment, individualized shunt diameter optimization, spontaneous portosystemic shunt embolization during the TIPS procedure, postoperative preventive and therapeutic measures such as nutrition management, medical therapy, fecal microbiota transplantation, and stent reduction.},

abstract = {Thalidomide (THA) is renowned for its potent anti-inflammatory properties. This study aimed to elucidate its underlying mechanisms in the context of Crohn's disease (CD) development. Mouse colitis models were established by dextran sulfate sodium (DSS) treatment. Fecal microbiota and metabolites were analyzed by metagenomic sequencing and mass spectrometry, respectively. Antibiotic-treated mice served as models for microbiota depletion and transplantation. The expression of forkhead box P3[+] (FOXP3[+]) regulatory T cells (Tregs) was measured by flow cytometry and immunohistochemical assay in colitis model and patient cohort. THA inhibited colitis in DSS-treated mice by altering the gut microbiota profile, with an increased abundance of probiotics Bacteroides fragilis, while pathogenic bacteria were depleted. In addition, THA increased beneficial metabolites bile acids and significantly restored gut barrier function. Transcriptomic profiling revealed that THA inhibited interleukin-17 (IL-17), IL-1β and cell cycle signaling. Fecal microbiota transplantation from THA-treated mice to microbiota-depleted mice partly recapitulated the effects of THA. Specifically, increased level of gut commensal B. fragilis was observed, correlated with elevated levels of the microbial metabolite 3alpha-hydroxy-7-oxo-5beta-cholanic acid (7-ketolithocholic acid, 7-KA) following THA treatment. This microbial metabolite may stable FOXP3 expression by targeting the receptor FMR1 autosomal homolog 1 (FXR1) to inhibit autophagy. An interaction between FOXP3 and FXR1 was identified, with binding regions localized to the FOXP3 domain (aa238-335) and the FXR1 domain (aa82-222), respectively. Conclusively, THA modulates the gut microbiota and metabolite profiles towards a more beneficial composition, enhances gut barrier function, promotes the differentiation of FOXP3[+] Tregs and curbs pro-inflammatory pathways.},

METHODS: We utilized metagenomic sequencing technology to conduct a detailed analysis of the fecal bacterial communities of six Red Back Pine Root Snakes (Oligodon formosanus, XT) and three Chinese Slug-Eating Snakes (Pareas chinensis, Z) individuals. The microbial composition was assessed through taxonomic profiling, alpha diversity analysis, and functional annotation using the Kyoto Encyclopedia of Genes and Genomes (KEGG) database.

RESULTS: The results indicated that Proteobacteria, Bacteroidetes, Firmicutes, Verrucomicrobia, Actinobacteria, and Fusobacteria were the dominant phyla in XT samples, while Z samples additionally contained Patescibacteria. Alpha diversity analysis revealed significant differences in species abundance at the family level, with Z samples exhibiting higher microbial richness than XT. Furthermore, KEGG analysis showed that XT had higher functional gene abundance in pathways related to transcription, translation, environmental adaptation, membrane transport, cellular communities (prokaryotes), motility, and replication/repair compared to Z.

DISCUSSION: This study provides a comparative analysis of their gut microbiomes, offering valuable insights for future research on zoonotic diseases, host-microbe interactions, and ecological, evolutionary, behavioral, and seasonal influences on snake microbiota. These findings contribute to a broader understanding of microbial ecology in reptiles and its implications for conservation and disease dynamics.},

abstract = {A high-fat, low-fibre Western-style diet (WD) induces microbiome dysbiosis characterized by reduced taxonomic diversity and metabolic breadth[1,2], which in turn increases risk for a wide array of metabolic[3-5], immune[6] and systemic pathologies. Recent work has established that WD can impair microbiome resilience to acute perturbations such as antibiotic treatment[7,8], although little is known about the mechanism of impairment and the specific consequences for the host of prolonged post-antibiotic dysbiosis. Here we characterize the trajectory by which the gut microbiome recovers its taxonomic and functional profile after antibiotic treatment in mice on regular chow (RC) or WD, and find that only mice on RC undergo a rapid successional process of recovery. Metabolic modelling indicates that a RC diet promotes the development of syntrophic cross-feeding interactions, whereas in mice on WD, a dominant taxon monopolizes readily available resources without releasing syntrophic byproducts. Intervention experiments reveal that an appropriate dietary resource environment is both necessary and sufficient for rapid and robust microbiome recovery, whereas microbial transplant is neither. Furthermore, prolonged post-antibiotic dysbiosis in mice on WD renders them susceptible to infection by the intestinal pathogen Salmonella enterica serovar Typhimurium. Our data challenge widespread enthusiasm for faecal microbiota transplant (FMT) as a strategy to address dysbiosis, and demonstrate that specific dietary interventions are, at a minimum, an essential prerequisite for effective FMT, and may afford a safer, more natural and less invasive alternative.},

Research has consistently shown bidirectional communication between the gut and the brain through neuronal, endocrine, and immunological, and chemical pathways. Recent neuroscience studies have linked changes in the microbiome and microbial metabolites to various neuropsychiatric disorders such as autism, depression, anxiety, schizophrenia, eating disorders, and neurocognitive disorders. Novel metagenome-wide association studies have confirmed these microbiome variations in large samples and expanded our understanding of the interactions between human genes and the gut microbiome. The causal relationship between gut microbiota and neuropsychiatric disorders is being elucidated through the establishment of large cohort studies incorporating microbiome data and advanced statistical techniques. Ongoing animal and human studies focused on the microbiota-gut-brain axis are promising for developing new prevention and treatment strategies for neuropsychiatric conditions. The scope of these studies has broadened from microbiome-modulating therapies including prebiotics, probiotics, synbiotics and postbiotics to more extensive approaches such as fecal microbiota transplantation. Recent systematic reviews and meta-analyses have strengthened the evidence base for these innovative treatments. Despite extensive research over the past decade, many intriguing aspects still need to be elucidated regarding the role and therapeutic interventions of the microbiota-gut-brain axis in neuropsychiatric disorders.},

Loss of IL-10 signaling in IMs initiated an inflammatory cascade through the activation of classical monocytes and CD4[+] T cell subsets, leading to chronic lung inflammation with age. Analyses of antibiotic-treated and germ-free mice established that lung inflammation in the animals lacking IL-10 signaling was triggered by commensal bacteria. 16S rRNA sequencing revealed Delftia acidovorans and Rhodococcus erythropolis as potential drivers of lung inflammation. Intranasal administration of these bacteria or transplantation of human fecal microbiota elicited lung inflammation in gnotobiotic Il10-deficient mice. These findings highlight that IL-10 sensing by IMs contributes to pulmonary homeostasis by preventing lung inflammation caused by commensal dysbiosis.},

abstract = {BACKGROUND: Dysbiosis of the gut microbiota is pivotal in the development of gastric mucosa injury (GMI). Glycyrrhetinic acid (GA) is a bioactive triterpenoid compound abundantly present in licorice roots. Although GA's potential in mitigating GMI is recognized, its precise mechanism remains elusive, particularly concerning the role of gut microbiota.

PURPOSE: This study aimed to explore the protective effects and mechanisms of GA in preventing HCl/ethanol-induced GMI in rats.

RESULTS: This study demonstrated the protective effects of GA on gastric mucosa, evidenced by enhanced morphology and structure as revealed through H&E staining. Utilizing fecal microbiota transplantation, GA was found to significantly mitigate oxidative damage, inflammation, and expression of apoptosis-related genes in GMI rats by a gut microbiota-dependent mechanism. 16S rRNA sequencing and metabolomics profiling revealed that GA ameliorated HCl/ethanol-triggered intestinal dysbiosis and imbalances in sphingolipid, arginine, and tryptophan metabolism. By promoting the prevalence of Bifidobacterium longum subsp. infantis (B. infantis) in the gut microbiota, GA improved metabolic disturbances linked to injury. Furthermore, its action mechanism was related to the inhibition of the Thbs1/PI3K-Akt/p53 signaling pathway.

CONCLUSION: The administration of GA improves GMI by mitigating intestinal dysbiosis and fostering colonization of B. infantis. GA offers therapeutic potential for GMI by modulating the Thbs1/PI3K-Akt/p53 pathway, thus alleviating inflammatory responses associated with gut microbiota imbalance.},

However, studies on the influence of gut microbiota on acute radiation-induced intestinal injury are inconsistent. In this study, we established an acute radiation-induced intestinal injury mouse model and performed fecal microbiota transplantation to explore the role of the gut microbiota in acute radiation-induced intestinal injury. We observed a significant increase in Akkermansia muciniphila following irradiation, whereas fecal microbiota transplantation effectively reduced Akkermansia muciniphila levels. Contrary to expectations, Akkermansia muciniphila supplementation increased acute radiation-induced intestinal injury and mortality. Mechanistically, post-radiation Akkermansia muciniphila upregulates mucin metabolism genes and consumes mucin, thinning the mucosal barrier and promoting the adhesion and translocation of potential pathogens to epithelial cells, thus exacerbating acute radiation-induced intestinal injury. This enables Akkermansia muciniphila to use mucin as an energy source. Additionally, Akkermansia muciniphila increases the inflammatory macrophage changes and secretion of inflammatory cytokines, leading to a decrease in epithelial stem cell density and inhibition of goblet cell differentiation, further exacerbating acute radiation-induced intestinal injury. Our findings suggest that in certain intestinal environments, the addition of Akkermansia muciniphila may worsen radiation-induced intestinal damage; thus, alternative approaches to reverse the dysbiosis associated with radiotherapy should be explored.},

Additionally, dysbiosis influences the efficacy and toxicity of cancer therapies. Given these associations, there is growing interest in leveraging the microbiota as a biomarker for cancer detection and outcome prediction. Notably, distinct microbial signatures have been identified across various cancer types, suggesting their potential as diagnostic markers. Furthermore, modulation of the microbiota presents a promising avenue for improving cancer treatment outcomes through strategies such as antibiotics, prebiotics, probiotics, fecal microbiota transplantation, dietary interventions, small-molecule inhibitors, and phage therapy. To explore these relationships, we conducted a comprehensive literature review using Web of Science, Scopus, PubMed, MEDLINE, Embase, and Google Scholar as our primary online databases, focusing on indexed peer-reviewed articles up to the present year.

We aimed to investigate the effects of short-chain fatty acids (SCFAs) treatment on PND via mediating Brain-derived neurotrophic factor (BDNF)/Phosphatidylinositol3-kinase (PI3K)/Protein kinase B (Akt) pathway. Using 16S rDNA sequencing targeting the V3-V4 hypervariable regions, we first demonstrated significant gut microbiota dysbiosis in PND model rats, accompanied by altered SCFAs profiles. Subsequent fecal microbiota transplantation (FMT) experiments established causal relationships between PND-associated microbial alterations and spatial cognitive deficits. Mechanistically, SCFAs supplementation attenuated neuronal damage and restored synaptic plasticity, as evidenced by Nissl staining quantification (reduced chromatolysis), TUNEL assay (decreased apoptosis rate), and immunohistochemical analysis (upregulated NeuN expression). Molecular investigations revealed that SCFAs-mediated cognitive improvement involved BDNF upregulation and subsequent PI3K/Akt pathway activation, ultimately enhancing neuronal survival and synaptic integrity. Notably, PND animals exhibited characteristic neuropathological features including synaptic density reduction (PSD-95 downregulation), neuroinflammation amplification (IL-6 elevation), and apoptosis activation-all significantly reversed by SCFA intervention. Our findings establish a novel gut-brain axis mechanism wherein microbiota-derived SCFAs may exert neuroprotection through BDNF-dependent PI3K/Akt signaling, and offer potential therapeutic strategies for PND management.},

However, the poor patient acceptability and accessibility of 'conventional' FMT, typically administered via colonoscopies or enemas, hinders its widespread clinical adoption, particularly for chronic conditions. Oral administration of FMT (OralFMT) overcomes these limitations, yet faces distinct challenges, including a significant capsule burden, palatability concerns and poor microbial viability during gastric transit. This review provides a comprehensive analysis of emerging strategies that aim to advance OralFMT by: (1) refining processing technologies (eg, lyophilisation) that enable manufacturing of low-volume FMT formulations for reducing capsule burden and (2) developing delivery technologies that improve organoleptic acceptability and safeguard the microbiota for targeted colonic release. These advancements present opportunities for OralFMT to expand its therapeutic scope, beyond C. difficile infections, towards chronic GI conditions requiring frequent dosing regimens. While this review primarily focuses on optimising OralFMT delivery, it is important to contextualise these advancements within the broader shift towards defined microbial consortia. Live biotherapeutic products (LBPs) offer an alternative approach, yet the interplay between OralFMT and LBPs in clinical practice remains unresolved. We postulate that continued innovation in OralFMT and LBPs via a multidisciplinary approach can further increase therapeutic efficacy and scalability by enabling disease site targeting, co-delivery of therapeutic compounds and overcoming colonisation resistance. Realising these goals positions OralFMT as a cornerstone of personalised care across a range of diseases rooted in microbiome health.},

abstract = {The gut microbiota plays an important role in maintaining host health by affecting various physiological functions. Among the diverse microbial communities in the gut, prophages are integral components of bacterial genomes, contributing significantly to bacterial evolution, ecology and pathogenicity. Prophages are capable of switching to lytic cycles in response to various internal and external factors. Factors that induce prophage induction include DNA damage, oxidative stress, nutrient availability, host immune response, quorum sensing, diet, secondary metabolites, antibiotics, and lifestyle changes. Prophage induction could contribute to both gut homeostasis and dysbiosis. Importantly, the connections between prophage induction and disorders such as inflammatory bowel disease, ulcerative colitis, and bacterial vaginosis highlight the dual roles of prophages in both health and disease. Although therapeutic approaches such as phage therapy (PT), fecal microbiota transplants (FMT), and fecal virome transplants (FVT) have gained attention, the concept of dietary prophage induction therapy offers a novel, targeted method to modulate gut microbiota. In spite of recent advances in understanding the role of prophages in gut health, the exact mechanisms by which they influence gut health remain only partially understood. Therefore, further research is needed to elucidate additional molecular mechanisms of prophage induction pathways and to explore their implications for gut microbiota dynamics and disease associations. This review discusses the molecular mechanisms and key factors that trigger prophage induction in the gut. Insights into these processes could lead to innovative therapeutic strategies that utilize prophages to support gut health.},

abstract = {The intestinal mucus barrier has emerged as a promising therapeutic target for inflammatory bowel disease. Understanding its regulatory mechanisms is critical for elucidating ulcerative colitis (UC) pathogenesis, improving diagnostics, guiding treatments, and preventing relapse. Chloride Channel Accessory 1 (Clca1), a constituent of the mucus layer, remains understudied in colitis. Here, we investigated Clca1's role in mucosal immunity and intestinal homeostasis using experimental colitis models. Clca1-deficient (Clca1[-/-]) mice displayed compromised mucus layer integrity, reduced neutrophil infiltration, and gut microbiota dysbiosis. Notably, Clca1[-/-] mice exhibited exacerbated colitis severity following dextran sulfate sodium (DSS) challenge, accompanied by a diminished goblet cell populations. Fecal microbiota transplantation (FMT) studies revealed that gut microbiota critically modulates divergent phenotypic outcomes between genotypes. Our findings establish Clca1 as a multifunctional regulator of mucus barrier integrity through mechanisms involving goblet cell maintenance, neutrophil-mediated immunity, and host-microbiota crosstalk. These results advance the understanding of UC pathogenesis and identify Clca1-associated pathways as potential targets for barrier restoration therapies.},

Here, C57BL/6J male mice were exposed to TPHP or DPHP for 12 weeks at estimated daily intake doses of 0.1 and 7 μg/kg bw/day. TPHP intake affected the levels of short-chain fatty acids and bile acids in the gut, enhancing the production of 29 medium- and long-chain fatty acids in the liver by 3.72-fold and significantly increasing hepatic lipid and cholesterol levels. Metabolomic and molecular analysis confirmed that elevated liver cholesterol levels persisted after an 8 week recovery period. Gut microbiota-dependent cholesterol alterations were the toxic end points observed in TPHP-fed mice, as supported by the results of fecal microbiota transplantation. In DPHP-fed mice, serotonergic and glutamatergic synapses were simultaneously altered in the liver and intestine, corresponding to the reduction of five brain neurotransmitters (15.4-60.8%). Decreased liver carbohydrate levels and insulin resistance were observed in the DPHP-fed mice. These results suggest that TPHP and DPHP affect metabolism via different toxic modes, mediated through the gut-liver axis, providing novel insights into the mechanisms of organophosphate-ester-mediated metabolic disruption.},

abstract = {The gut-brain axis (GBA) represents a sophisticated bidirectional communication system connecting the central nervous system (CNS) and the gastrointestinal (GI) tract. This interplay occurs primarily through neuronal, immune, and metabolic pathways. Dysbiosis in gut microbiota has been associated with multiple neurodegenerative diseases, such as Parkinson's disease (PD), Alzheimer's disease (AD), multiple sclerosis (MS), and amyotrophic lateral sclerosis (ALS). In recent years, fecal microbiota transplantation (FMT) has gained attention as an innovative therapeutic approach, aiming to restore microbial balance in the gut while influencing neuroinflammatory and neurodegenerative pathways. This review explores the mechanisms by which FMT impacts the gut-brain axis. Key areas of focus include its ability to reduce neuroinflammation, strengthen gut barrier integrity, regulate neurotransmitter production, and reinstate microbial diversity. Both preclinical and clinical studies indicate that FMT can alleviate motor and cognitive deficits in PD and AD, lower neuroinflammatory markers in MS, and enhance respiratory and neuromuscular functions in ALS. Despite these findings, several challenges remain, including donor selection complexities, uncertainties about long-term safety, and inconsistencies in clinical outcomes. Innovations such as synthetic microbial communities, engineered probiotics, and AI-driven analysis of the microbiome hold the potential to improve the precision and effectiveness of FMT in managing neurodegenerative conditions. Although FMT presents considerable promise as a therapeutic development, its widespread application for neurodegenerative diseases requires thorough validation through well-designed, large-scale clinical trials. It is essential to establish standardized protocols, refine donor selection processes, and deepen our understanding of the molecular mechanisms behind its efficacy.},

This is explained by the hypothesis of multiple parallel hits. These factors are insulin resistance, lipid metabolism alteration, oxidative stress, endoplasmic reticulum stress, inflammatory cytokine liberation, gut microbiota dysbiosis or gut-liver axis activation. This is a systematic review which has an aim to show the connection between intestinal microbiota and the role of its disbalance in the development of NAFLD. The gut microbiota is made from a wide spectrum of microorganisms that has a systemic impact on human health, with a well-documented role in digestion, energy metabolism, the stimulation of the immune system, synthesis of essential nutrients, etc. It has been shown that dysbiosis is associated with all three stages of chronic liver disease. Thus, the modulation of the gut microbiota has attracted research interest as a novel therapeutic approach for the management of NAFLD patients. The modification of microbiota can be achieved by substantial diet modification and the application of probiotics or prebiotics, while the most radical effects are observed by fecal microbiota transplantation (FMT). Given the results of FMT in the context of metabolic syndrome (MetS) and NAFLD in animal models and scarce pilot studies on humans, FMT seems to be a promising treatment option that could reverse intestinal dysbiosis and thereby influence the course of NAFLD.},

abstract = {CONTEXT: Despite an increasing body of research showing gut microbiota-based interventions can improve gastrointestinal (GI) symptoms and behavioral symptoms in both humans and animals, there are still disagreements about its impact on autism spectrum disorder (ASD) in children.

OBJECTIVE: The goal of this systematic review and meta-analysis was to fully investigate the effects of gut microbiota-based interventions (eg, fecal microbiota transplantation, probiotics, prebiotics) on GI and behavioral symptoms in children with ASD.

DATA SOURCES: The PubMed, Web of Science, the Cochrane Library, China National Knowledge Infrastructure, and Scopus databases were searched from inception to August 25, 2024.

DATA EXTRACTION: Data were extracted by 2 reviewers independently, and discrepancies in authors' judgments were resolved by discussion or consulting a third author.

DATA ANALYSIS: The scale score of GI and behavioral symptoms before and after the intervention was extracted from included trials to evaluate the therapeutic effects of gut microbiota-based therapy in children with autism.

RESULTS: A total of 5722 records were identified, of which 13 included in narrative synthesis and 8 studies included a meta-analysis. The nonsignificant overall effect size of gut microbiota-based intervention on GI symptoms (standardized mean difference [SMD] = -0.34 [95% CI, -0.76 to 0.07]; P = .11) and behavioral symptoms (SMD = -0.18 [95% CI, -0.37 to 0.02]; P = .08) was observed. Nevertheless, we observed a significant effect size on behavioral symptoms in the subgroup of the intervention duration (SMD = -0.26 [95% CI, -0.49 to -0.03]; P = .02).

CONCLUSIONS: In children with autism, the proof supporting the validity of gut microbiota-based intervention on GI and behavioral symptoms should be interpreted cautiously. More randomized controlled trials with rigorous methodological quality are required to precisely confirm the curative benefits of gut microbiota-based interventions on GI and behavioral symptoms in children with autism.

abstract = {The human gut microbiota-an intricate and dynamic ecosystem-plays a pivotal role in metabolic regulation, immune modulation, and the maintenance of intestinal barrier integrity. Although antibiotic therapy is indispensable for managing bacterial infections, it profoundly disrupts gut microbial communities. Such dysbiosis is typified by diminished diversity and shifts in community structure, especially among beneficial bacterial genera (e.g., Bifidobacterium and Eubacterium), and fosters antibiotic-resistant strains and the horizontal transfer of resistance genes. These alterations compromise colonization resistance, increase intestinal permeability, and amplify susceptibility to opportunistic pathogens like Clostridioides difficile. Beyond gastrointestinal disorders, emerging evidence associates dysbiosis with systemic conditions, including chronic inflammation, metabolic syndrome, and neurodegenerative diseases, underscoring the relevance of the microbiota-gut-brain axis. The recovery of pre-existing gut communities post-antibiotic therapy is highly variable, influenced by drug spectrum, dosage, and treatment duration. Innovative interventions-such as fecal microbiota transplantation (FMT), probiotics, synbiotics, and precision microbiome therapeutics-have shown promise in counteracting dysbiosis and mitigating its adverse effects. These therapies align closely with antibiotic stewardship programs aimed at minimizing unnecessary antibiotic use to preserve microbial diversity and curtail the spread of multidrug-resistant organisms. This review emphasizes the pressing need for microbiota-centered strategies to optimize antibiotic administration, promote long-term health resilience, and alleviate the disease burden associated with antibiotic-induced dysbiosis.},

abstract = {Prostate cancer (PCa) is the second most common malignant tumor in men worldwide, and its metastatic and heterogeneous nature makes it significantly more difficult to treat. Recent studies have revealed the critical role of microbiota in PCa occurrence, progression, and treatment. Accumulating evidence from 16S rRNA and metagenomic sequencing suggests the presence of specific microbiota in prostate tissues and macrogenomics techniques: cancerous tissues are enriched with pro-inflammatory genera (e.g., Fusobacterium, Propionibacterium acnes), whereas commensal bacteria (e.g., Pseudomonas) are more common in paracancerous tissues. The microbiota drive tumor progression through activation of the NF-κB/STAT3 pathway to induce chronic inflammation, modulation of the immune microenvironment (e.g., Treg/Th17 imbalance and M2-type macrophage polarization), and metabolite (e.g., LPS, short-chain fatty acids)-mediated hormonal and epigenetic regulation. In terms of clinical translation, urinary microbiota characterization combined with metabolomics analysis may enhance diagnostic specificity, while gut flora modulation (e.g., probiotic interventions or fecal transplants) may improve resistance to androgen deprivation therapy. Current challenges include sequencing accuracy of low-biomass samples, limitations of causal mechanism validation models, and large cohort heterogeneity. In the future, it will be necessary to integrate multi-omics technologies to explore the bidirectional regulation of the "gut-prostate axis" and develop personalized therapeutic strategies targeting microorganisms. In this paper, we systematically review the interactions between microbiota and PCa and their clinical potentials to provide a theoretical basis for precision diagnosis and treatment.},

abstract = {BACKGROUND: Clostridioides difficile infection (CDI) has emerged as a prevalent and recurrent antibiotic-associated infection. Fecal microbiota transplantation (FMT) is the most effective treatment for recurrent CDI (rCDI). Despite high success rates, FMT is ineffective in 5%-20% of cases. Factors associated with failure have not been clearly defined.

OBJECTIVES: In this study, we seek to identify factors predictive of FMT failure.

DESIGN: Retrospective cohort study.

METHODS: A retrospective chart review was conducted on adult patients who were screened at the Complicated C. difficile Clinic at the University of Virginia Health System and received FMT for rCDI between 2013 and 2022. The primary outcome was failure of FMT, defined as either rCDI or all-cause death within 1 year.

RESULTS: In total, 240 patients underwent FMT: 70.4% were female, the median age was 68, and the median episode of CDI was 4. A total of 24.6% experienced failure within 1 year (18.3% had rCDI and 7.1% died). Age 70 or older (odds ratio (OR) = 2.66 (1.29-5.67)), ⩾4 episodes of CDI (OR = 3.13 (1.47-7.09)), and diabetes mellitus (OR = 2.82 (1.25-6.50)) were associated with failure on multivariate analysis.

CONCLUSION: Our study shows that FMT remains an effective treatment for rCDI. We highlight several factors associated with FMT failure, such as older age, ⩾4 episodes of CDI, and diabetes mellitus, and the need for additional research to clearly define causality.},

abstract = {The gut microbiota plays a crucial role in the manifestation of intestinal dysfunction associated with irritable bowel syndrome (IBS). The mechanosensory Piezo2 has been implicated in the regulation of intestinal function. However, it remains unclear whether Piezo2 is modulated by the gut microbiota, thus contributing to the development of visceral hypersensitivity and gut dysmotility. The study enrolled patients with diarrhea-predominant IBS (IBS-D) alongside healthy controls (HC). Questionnaires, rectal barostat test, and colonoscopy with mucosal biopsy were conducted. Fecal microbiota transplantation (FMT) was performed using samples from HC or IBS-D patients, and interventions with Akkermansia muciniphila or Fusobacterium varium were carried out on colon- or dorsal root ganglion (DRG)- Piezo2 knockdown pseudo-germ-free mice. Visceral sensitivity and intestinal motility were assessed. Piezo2 levels were detected using western blot and immunofluorescence. Fecal 16S rRNA sequencing and cecum untargeted metabolomics analysis, followed by molecular docking predictions of Piezo2, were also performed. The ratio of Piezo2[+]/5-HT[+] cells was lower in IBS-D patients, positively correlated with visceral sensation and intestinal dysbiosis. The mice that received FMT from IBS-D patients exhibited colonic dysmotility and visceral hypersensitivity, along with elevated Piezo2 protein levels in the colon and DRG. Knockdown of Piezo2 in the colon or DRG ameliorated the FMT-induced colonic dysmotility and visceral hypersensitivity. Fecal 16S rRNA sequencing revealed distinct microbiota composition. Notably, Fusobacterium varium, but not Akkermansia muciniphila, induced gut dysmotility and visceral hypersensitivity, effects that could be alleviated by colon or DRG Piezo2 knockdown. Additionally, Fusobacterium varium lead to increased Piezo2 protein levels, as well as elevated levels of indole-3-acetic acid and indole-3-acrylic acid, which were predicted to bind to Piezo2, causing disturbances. Piezo2 can be regulated by gut microbiota and involved in visceral hypersensitivity and colonic dysmotility, with Fusobacterium varium playing a crucial role.},

abstract = {BACKGROUND: The gut microbiome has been identified as a pivotal factor in ulcerative colitis (UC), given its role as the main reservoir of microbes in the body. This community of microorganisms, present in variable concentrations in the digestive tract, makes a wide range of beneficial roles for the host. However, the role of the gut microbiome in patients with refractory UC is still significant, so this study aimed to further investigate the role of these bacteria in patients with refractory UC.

METHODS: This case-control study was conducted on stool samples from four distinct groups: the first group comprised new patients diagnosed with ulcerative colitis (all of them had responded to treatment after follow-up) (N = 24); the second group consisted of patients with treatment-resistant ulcerative colitis (N = 23); the third group included first-degree relatives of group 1 patients (N = 24); and the fourth group consisted of first-degree relatives of group 2 patients (N = 23). The research tools employed in this study included a questionnaire, quantitative real-time PCR (qPCR) test, and culture on stool samples.

RESULT: The mean age of patients in groups 1 and 2 was 45.88 ± 18.51 and 41.30 ± 13.01 years, while the mean age of controls in groups 3 and 4 was 37.29 ± 9.62 and 40.96 ± 13.01 years, respectively. Stool culture results for pathogenic bacteria were negative in all four groups. The of history of consuming dairy products containing probiotics was highest in Group 1, with 22 (91.67%) subjects, while the lowest was observed in Group 3, with 16 (66.67%). The highest history of self-administered antibiotic use was observed in Group 2, with 13 cases (56.52%), while the lowest was noted in Group 3, with 4 cases (16.67%). The findings indicated a statistically significant relationship (P < 0.05) between Groups 2 and 4 with respect to the E. coli and Bifidobacterium ssp. microbial population. Additionally, a significant relationship was identified between the Lactobacillus ssp., Bifidobacterium ssp., and Bacteroides ssp. microbial community between groups 1 and 2 (P < 0.05).

CONCLUSION: The findings of this study demonstrated that several intestinal microbiomes have a substantial impact on the management of ulcerative colitis. The results of this study suggest that by comparing the gut microbiome of treatment-resistant and individuals newly diagnosed with ulcerative colitis, we can gain a better understanding of microbiome differences that may influence treatment outcomes. The results of this study may also lead to the identification of new therapeutic strategies that are based on regulating the gut microbiome. These strategies could include the use of fecal microbiome transplantation (FMT), probiotics, prebiotics, or specific bacteria-based therapies.},

A total of twenty-four rats were selected randomly for the study and divided into two groups, a control group, and an acid acetic-induced colitis group. The acid acetic-induced colitis group further consisted of three subgroups: untreated acid acetic-induced colitis group, mesalazine 0.3 gr/kg group, and FMT group. After 6 days, the colon was evaluated for macroscopic and microscopic damage, and the signaling pathway NLRP3-Caspase1-related genes in the colon and hippocampus were analyzed. Additionally, anxiety-related behaviors of the rats were observed. FMT decreased colonic mRNA expression levels of NLRP3, NF-кB, and Caspase1 and pro-inflammatory cytokines (IL-1β and IL-18). Also, FMT reduced the expression of NLRP3, NF-κB, and Caspase1 protein levels as well as pro-inflammatory cytokines IL-1β and IL-18 in the hippocampus, resulting in a reduction of anxiety behaviors in the open field and elevated plus maze tests in the colitis model. FMT may improve acetic acid-induced colitis by regulating the NLRP3-Caspase1 signaling pathway in the colon. It also reduced colitis-induced anxiety behavior by regulating the expression of proteins related to the NLRP3-Caspase 1 pathway in the hippocampus.},

A positive correlation has been observed between the intake of dietary fat and the development of CRC. The composition of gut microbiota exhibits a significant correlation with pathophysiologic processes in intestine. Clinical treatment remains inadequate due to the complex pathogenic mechanisms of CRC triggered by a high-fat diet (HFD). Naringenin, a flavonoid from grapefruit, has anti-cancer activity. Our findings suggest that naringenin enhances gut microbiota diversity by increasing the abundance of beneficial bacterial species while reducing opportunistic pathogenic bacteria. The fecal microbiota transplantation assay (FMT) demonstrated that the anti-HFD-CRC activity of naringenin depended on the gut microbiota. Furthermore, naringenin antagonized the IL-6/STAT3 pathway. These results suggest that naringenin may be a potential treatment for HFD-CRC.},
