Immunity 53, 217232.e5 (2020). 214, 309317 (2017). Lymphoid polyps (present in 15% of patients) are hyperplastic submucosal lymphoid aggregates, most likely due to a nonspecific infection (exposure to bacteria and viruses). Bergqvist, P. et al. When assessing FH, we rely on clinical evaluation, including elimination diet and challenge tests, and endoscopic and immunohistochemical findings. Peyer's patches are small masses of lymphatic tissue found throughout the ileum region of the small intestine.Also known as aggregated lymphoid nodules, they form an important part of the immune system by monitoring intestinal bacteria populations and preventing the growth of pathogenic bacteria in the intestines. 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. Med. Bemark, M. et al. 104, 280285 (1996).

[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. 137, 12131214 (2017).

Spencer, J. PLoS ONE 11, e0146010 (2016). The upper aerodigestive tract and small and large intestines have endogenous lymphoid tissue, including the Waldeyer ring in the oropharynx, Peyer patches in the terminal ileum, and mucosal lymphoid aggregates in the appendix. [18] There are two main ways of IgA production 1) T-cell dependent resulting in sIgAs with high affinity and specificity and 2) T-cell independent generation of sIgA, which utilizes dendritic cells and their production of BAFF and APRIL cytokines. 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. Majority of antigen presenting cells (APCs) in intestine is derived from macrophages, which have very quick turnover. Am.
