Microbial metabolites-including short-chain fatty acids, bile acid derivatives, indole compounds, and tryptophan-derived serotonin-activate receptors such as G-protein-coupled receptor 41/43, Takeda G protein-coupled receptor 5, and Toll-like receptor 4 on enteroendocrine cells, influence the secretion of appetite-related hormones including ghrelin, leptin, glucagon-like peptide-1, peptide YY, nesfatin-1, and cholecystokinin. These hormones subsequently modulate hypothalamic circuits, particularly the NPY/AgRP and POMC/CART pathways, establishing a mechanistic link between microbial signaling and central appetite control. Ghrelin serves as the primary orexigenic hormone, whereas leptin, glucagon-like peptide-1, peptide YY, nesfatin-1, and cholecystokinin collectively exert anorexigenic effects that promote satiety and energy homeostasis. Dysbiosis disrupts receptor-mediated endocrine signaling, alters hormonal secretion, and contributes to leptin resistance, impaired glucagon-like peptide-1 responsiveness, and dysregulated appetite-key features in obesity, insulin resistance, and metabolic syndrome. This review synthesizes current mechanistic insights into the microbiota-hormone axis and highlights how microbial modulation influences endocrine appetite regulation. Understanding these interactions provides a translational framework for developing microbiota-targeted endocrine therapies aimed at restoring metabolic balance and preventing obesity and related metabolic disorders.</p>","PeriodicalId":12999,"journal":{"name":"Hormone and Metabolic Research","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147837360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
