WebA common disorder, affecting about 1% of the population, patients can present with a variety of intestinal and non-intestinal symptoms. Autoantibodies such as tissue transglutaminase antibody (TTG), endomysial antibody (EMA) and deamidated gliadin peptide (DGP) are produced in the body and form the basis of serological tests used for screening. Webbowel brush border most notably resulting in gliadin. Gliadin is then broken down by tissue transglutaminase (tTG) resulting in deaminated gliadin. About 1% of the general population has developed antibodies to various enzymes and products along this pathway resulting in clinical manifestations of celiac disease [1,4].

WebOnce gliadin reaches the lamina propria, it is deamidated by tissue transglutaminase (TTG). Deamidated gliadin then reacts with HLA-DQ2 or HLA-DQ8 receptors on antigen-presenting cells that stimulate T- and B-cell activation, leading to cytokine release, antibody production, and lymphocyte infiltration.
