WebApr 8, 2024 · To overcome the limitation of gliadin-based serology,clinicians should remember that EMA has the highest specificity for diagnosing CD,and IgA-tTG remains the best test for initial screening with very high sensitivity and specificity[34,35]. 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.
