House Officer Celiac disease is an autoimmune condition where the body responds to gluten in the diet by the immune system going in an overdrive and affecting the inner walls of the small intestines. Celiac disease is a multifactorial, autoimmune disorder that occurs in genetically susceptible individuals. Most cited articles. Introduction. According to the World Gastroenterology Organization, celiac disease may be divided into two types: classical and non-classical. The genetic factors are HLA DQ2 or DQ8 as well as non HLA genes. Curr Opin Immunol. •Celiac disease is an autoimmune disorder of the small intestine that occurs in genetically predisposed people of all ages from middle infancy. See our Privacy Policy and User Agreement for details. Celiac disease is the end result of 3 processes that culminate in intestinal mucosal damage : genetic predisposition, ... What these γΔ cells are doing in the epithelium is unknown, but they may alter the transfer and presentation of antigens by the enterocyte. MU-1.

Environmental trigger is represented by gl … Damage to the intestinal mucosa occurs with the presentation of gluten derived peptide gliadin by HLA molecules to helper T cells, which mediate the inflammatory response, causing epithelial damage Destruction of the intestinal absorptive surface leads to malabsorption Etiology. Review articles. Celiac disease occurs in any individual due to an interaction of genetic factors, environmental factors and gluten.

It’s a chronic (long-term) digestive disease in which patients have inflammation or irritation in the small intestine, which causes difficulties with absorbing nutrients from the diet.

A major milestone in the history of celiac disease was the identification of tissue transglutaminase as the autoantigen, thereby confirming the autoimmune nature of this disorder.
