To evaluate any potential correlation between anti-tissue transglutaminase antibodies of type immunoglobulin A (tTG-IgA) and the degree of gluten induced

A blood test that shows higher levels of anti-tissue transglutaminase antibodies can help your healthcare provider figure out if you have celiac disease. Why do I need this test? Arms: anti-tissue transglutaminase group. serum IgA-tissue transglutaminase antibody (tTG) was analyzed in serum using a quantitative automated ELISA method by means of a commercially available detection kit using recombinant human tTG as antigen recommended cut-off by the manufacturer > 8 U/mL). A number of lines of evidence suggest that transglutaminase 2 (TG2) may be one of the earliest disease-relevant proteins to encounter immunotoxic gluten in the celiac gut. These and other investigations also suggest that the reaction catalyzed by TG2 on dietary gluten peptides is essential for the pathogenesis of celiac disease. If so, several questions are of critical significance.

Despite low sequence identity, it imitates functionally … Role of Tissue Transglutaminase in Celiac Disease REACTIONS CATALYZED BY TISSUE TRANSGLUTAMINASE. The most established property of tTG and the other transglutaminases is STRUCTURE AND FUNCTIONAL ROLES OF TISSUE TRANSGLUTAMINASE. The transglutaminases are a large family of related enzymes ROLE 1.

tTG is suggested to exert at least two crucial roles in celiac disease: as a deamidating enzyme, that can enhance the immunostimulatory effect of gluten, and as a target autoantigen in the immune response. RESULTS: Untreated celiac patients had significantly higher titers of antitissue transglutaminase than healthy and disease controls (p < 0.00001).

Moreover, levels of tTG autoantibodies decline after gluten withdrawal, which enables objective evaluation of how patients respond to treatment with gluten-free diet.

Dr. Pastore covers a well-known, yet not well-understood diagnostic marker of celiac disease - tissue transglutaminase (TTG). He covers the function TTG plays as an enzyme, how TTG affects gluten and shares vital information about various TTG blood tests for those looking for a diagnosis, and for the diagnosed celiac wanting to monitor their progress.
