Lymphoid tissue is normally concentrated along the mucosal surfaces of the body (tonsils, Peyer patches) and can also be acquired at sites of chronic antigenic stimulation.

Then the receptor is proteolyticaly cleaved and the dimer of IgA is released with a portion of the receptor called the secretory component. Whereas all of them have a gut-associated lymphoid tissue and the vast majority have a version of spleen and thymus, not all vertebrates show bone marrow, lymph nodes or germinal centers, what means that not all vertebrates can generate lymphocytes in bone marrow. 233, 210 (2021).

Nat. [8] FAE differs from typical small intestinal villus epithelium: it has fewer goblet cells[9] therefore mucus layer is thinner,[10] and it is also characterized by the presence of specialized M cells or microfold cells, which provide uptake and transport of antigens from lumen. 20, 13341339 (2014).

Background: J. Immunol. Such a walking on the edge of a knife is ensured by diverse types of immune cells: Plasma B cells residing at lamina propria produce high levels of specific secretory IgA antibodies. If the amount of tissue is too small to make a diagnosis, the pathologist may recommend performing another biopsy and removing a larger tissue sample. Front. Med. This blog does not imply that UC Davis Health endorses the views expressed. 55, 9098 (2020). [19][20] General functions of secretory IgAs are to coat any of the intestinal bacteria (commensal or pathogenic ones) to impair their motility and to prevent them from getting in prolonged and direct contact with the intestinal epithelium and the host intestinal immune system.

Unlike enterocytes, these M cells present a folded luminal surface instead of the microvilli, do not secrete digestive enzymes or mucus and lack a thick surface of glycocalix, so it can be in contact with microbiota and antigens presented in the content of gut. Gasaly, N., de Vos, P. & Hermoso, M. A. Liang, L. et al. Gut-associated lymphoid tissue (GALT) is a component of the mucosa-associated lymphoid tissue (MALT) which works in the immune system to protect the body from invasion in the gut.
