摘要

In addition to the function of absorbing nutrients, intestines have many defense mechanisms against exogenous substances such as bacteria and chemicals. Intestinal epithelial cells, which cover the surface of intestines function to keep intestinal homeostasis not only by acting as a barrier but also by interacting with immune cells located in the intestinal epithelium via soluble factors. But, in the intestines of the patients suffering from intestinal inflammation, hyperproduction of inflammatory cytokines, especially TNF-alpha, from immune cells such as activated macrophages, and damage of intestinal epithelial cells is observed. This is one of the causes of intestinal inflammation.
