WebGliadin specific CD4+ helper T cells exist in the small intestinal mucosa of patients with coeliac disease.6, 7 These gliadin reactive helper T cells could, when the gliadin and the tTG antigens are linked, provide help for tTG specific B cells. 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.
