The gut mucus barrier and mechanical barrier are the most important natural barriers, the former is the first defense barrier, which separates pathogenic bacteria in intestinal lumen from the epithelial cells, and prevents them passing through the intestinal barrier into the human circulation system. Studies have shown that inflammation in the body affects the content of mucin 2, a key protein in the mucus layer, thereby changing the permeability of the mucus barrier and promoting the translocation of pathogenic microorganisms. Both tumor necrosis factor-α and c-jun N-terminal kinase signaling pathways have been reported to be closely related to the occurrence and development of inflammation. Therefore, this article reviews the relationship between tumor necrosis factor-α, c-jun N-terminal kinase signaling pathway and mucin 2 and intestinal barrier dysfunction, in order to provide new ideas and directions for exploring the related research of intestinal barrier function.
