Disease is limited to the small intestine in approximately 40-50% of cases, whereas another 30-40% of cases involve both the small intestine and the colon. When presented with dangerous pathogenic antigens, lymphocytes trigger the immune response by producing pathogen-specific antibodies; turning into pathogen-killing cytotoxic T lymphocytes; and migrating through lymphatic vessels to lymph nodes to alert the other cells of the immune system. 11, 447457 (1976).

X 20. In the small intestine, GALT is located between the muscularis mucosa and the FAE. There is also lymphatic circulation through the tissue connected to the mesenteric lymph nodes. Long, Y. et al. In addition, cells such as the Tfollicular helper cells, which are enriched in many autoinflammatory diseases, are intrinsically associated with the germinal centre microenvironment that is more abundant in the gut than in any other tissue in health.

Evidence that pathogenic transglutaminase 2 in celiac disease derives from enterocytes. The lymphatic system is a network of tissues, vessels and organs that work together to move a colorless, watery fluid called lymph back into your circulatory system (your bloodstream). [2] The lymphoid aggregates are usually noted in the mucosa and submucosa, although they can be located throughout the bowel wall and are characteristically seen in the subserosal fat . Patients suffering from gastrointestinal symptoms (i.e. Immunol. Prominent lymphoid aggregate: The term prominent is a descriptor often used to describe a lymphoid aggregate in GI mucosa that is larger than expected (thus possibly accounting for the endoscopic impression of a polyp).

After this activation, conventional IELs express gut-tropic molecules allowing them to home in intestinal tissue after trafficking through lymph stream and subsequent blood stream. [2], Peyer's patches had been observed and described by several anatomists during the 17th century,[3] but in 1677 Swiss anatomist Johann Conrad Peyer (16531712) described the patches so clearly that they were eventually named after him.

Peyer's patches are covered by a special follicle-associated epithelium that contains specialized cells called microfold cells (M cells) which sample antigen directly from the lumen and deliver it to antigen-presenting cells (located in a unique pocket-like structure on their basolateral side). CAS T-cell independently produced sIgAs have lower affinity and coat mainly commensals. 32, 289296 (2020). Conventional intraepithelial cells are thus tissue-resident effector memory T cells, capable of rapid respond with cytolytic activity and release of cytokines such as INF and TNF. Beside adaptive specific immunity, an innate immunity plays a significant role in GALT because it provides more rapid response.
