Peyer’s patches
|
Detailed explanation-1: -The gut-associated lymphoid tissue (GALT) consists of isolated or aggregated lymphoid follicles forming Peyer’s patches (PPs). By their ability to transport luminal antigens and bacteria, PPs can be considered as the immune sensors of the intestine.
Detailed explanation-2: -Peyer’s patch refers to any of the nodules of lymphatic cells which aggregate to result in the formation of patches or bundles. Furthermore, they exist in the lower section of the small intestine which is known as the ileum. Also, they are called as aggregated lymphoid nodules.
Detailed explanation-3: -Peyer’s patches are collections of lymphoid tissue that are part of the gut-associated lymphoid tissue. M cells are found not only in the intestinal tract, but also in the respiratory epithelium overlying bronchus-associated lymphoid tissue.
