Gut epithelial cells
WebThe gut epithelium serves as a barrier between the intestinal lumen and immune cells residing in gut-associated lymphoid tissues. These epithelial cells are required to respond to stimuli from the outside-in (e.g., microbiome and dietary components), as well as from the inside-out (e.g., cytokines and growth mediators). WebEpithelial cells line the major cavities of the body. Epithelia form the structure of the lung, including the alveoli or air sacs where gas exhange occurs. Cells line most organs, such as the stomach and small intestine, kidney, and pancreas. They also line the esophagus. Cells are also found in ducts and glands, like the bile duct and sailvary ...
