follicle associated epithelium
FAE
A specialized epithelial layer overlying the luminal surface of lymphoid follicles in gut-associated lymphoid tissue. It is found in Peyer's patches of the small intestine and appendix in humans and in the intestine and caecal patches in mice. This layer contains specialised M cells and has fewer goblet cells compared to surrounding tissue. This layer plays a crucial role in mucosal immune surveillance.
