Maintaining a robust epithelial barrier sequesters these potentially harmful substances in the lumen, preventing absorption into the systemic circulation. Normal functioning of this barrier is central in diverse physiological processes including digestion, immunity, inflammation, and gut-brain signaling. One crucial component of the barrier is the mucus layer covering the epithelium. There is increased appreciation of the importance of mucus in maintenance of the gut barrier, and how dysregulation of the mucus layer contributes to several common gastrointestinal pathologies. This manuscript reviews the physical and chemical properties of mucus, its maintenance and turnover, and its role in maintaining gut barrier integrity. The dynamic interactions of the mucus layer within the gut ecosystem are illustrated by highlighting how a weakened mucus layer or defective mucus production facilitate pathogenic microbial colonization and mucosal biofilm formation. These may potentially contribute to the pathogenesis of gastrointestinal diseases such as inflammatory bowel diseases or result in secretion and mucosal damage and inflammation in bile acid diarrhea. A final goal is to review how certain dietary factors, especially low-fiber diets and emulsifiers common in Western diets, can harm the mucus layer. This report summarizes evidence from preclinical and human studies that document damage to the mucus layer, and reviews approaches, including diets and probiotics, that promote a healthy mucus layer and break down pathogenic biofilms, thereby potentially preventing and/or treating gastrointestinal diseases that impact mucosal integrity.</p>","PeriodicalId":10347,"journal":{"name":"Clinical Gastroenterology and Hepatology","volume":" ","pages":""},"PeriodicalIF":11.6,"publicationDate":"2024-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142459521","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
