Abstract

Intestinal mucus, a viscoelastic medium with mucin2 (MUC2) as its main component, covers the surface of intestinal epithelial cells and protects the intestine from invasion, forming the first barrier of the intestinal tract. Unlike the small intestine, where the mucus layer is a single layer, the colonic mucus layer can be divided into a sterile inner layer and an outer layer with bacterial colonization. Many of the substances in the mucus layer have beneficial effects on the intestinal epithelium, but the mucus layer is often affected by a variety of factors, mainly microbiological, dietary, and immunological. Inflammatory bowel disease (IBD) is a disease of increasing morbidity worldwide, with a complex etiology and a high relapse rate. In recent years, the mucus barrier in IBD has received increasing attention and is considered a key factor in the pathogenesis of IBD. Loss of goblet cells (GCs) and changes in the composition and properties of the mucus layer material are commonly found in the colon of IBD patients. Damage to the mucus layer may make it easier for microorganisms to access the intestinal epithelium and cause inflammation. There are currently a number of herbs and other therapies that can be used to treat IBD and repair the damaged mucus barrier. This review highlights the important role of the mucus layer in IBD and the therapies that target the mucus layer in IBD.

期刊介绍: Autoimmunity Reviews is a publication that features up-to-date, structured reviews on various topics in the field of autoimmunity. These reviews are written by renowned experts and include demonstrative illustrations and tables. Each article will have a clear "take-home" message for readers. The selection of articles is primarily done by the Editors-in-Chief, based on recommendations from the international Editorial Board. The topics covered in the articles span all areas of autoimmunology, aiming to bridge the gap between basic and clinical sciences. In terms of content, the contributions in basic sciences delve into the pathophysiology and mechanisms of autoimmune disorders, as well as genomics and proteomics. On the other hand, clinical contributions focus on diseases related to autoimmunity, novel therapies, and clinical associations. Autoimmunity Reviews is internationally recognized, and its articles are indexed and abstracted in prestigious databases such as PubMed/Medline, Science Citation Index Expanded, Biosciences Information Services, and Chemical Abstracts.
