Abstract
The intestinal mucosal barrier is composed of intestinal epithelial cells and extracellular components, which has the characteristics of complex structure and diverse functions. In the form of dynamic changes, the intestinal mucosa barrier selectively absorbs water and nutrients, prevents intestinal bacterial translocation, and has intestinal immune function in the process of digestion, so as to help the body maintain the integrity of the intestinal tract and immune homeostasis. The causes of intestinal mucosal barrier dysfunction, such as chronic inflammation, dysbacteriosis, and changes in environmental factors, can independently or collaboratively cause biochemical cascade reactions, leading to the occurrence of chronic inflammation and a variety of intestinal diseases, such as inflammatory bowel disease, irritable bowel syndrome, colonic cancer, and some extraintestinal diseases (such as chronic nonalcoholic liver disease, type I diabetes, and obesity). It is of great significance to understand the mechanism of intestinal mucosal barrier dysfunction for the study of intestinal diseases or extraintestinal related diseases.
