Tissue transglutaminase (tTG) is a calcium dependent ubiquitous enzyme which catalyses posttranslational modification of proteins and is released from cells during inflammation. 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. Microbial transglutaminase is heavily used in the food processing industries to improve food qualities. Being a protein's glue, by cross-linking it creates neoepitope complexes that are immunogenic and potentially pathogenic in celiac disease. ROLE OF TISSUE TRANSGLUTAMINASE IN CELIAC DISEASE In a pioneering study in 1985, Bruce et al. (59) demonstrated that homogenates of intestinal biopsy specimens contain an enzyme that has the ability to cross-link labeled polyamines to a defined transglutaminase substrate.
It is paralleled by a food industry that is continuously introducing additives to processed products. Microbial transglutaminase (mTG) is an enzyme that deamidates/transamidates proteins, enabling cross-linkage of molecules and revolutionizing the properties of many food products. 2012-08-10 In celiac disease, highly sensitive and specific serum endomysial and transglutaminase 2 antibody tests are widely used in identifying patients for diagnostic endoscopy and small-bowel biopsy. When celiac disease is suspected, initial testing for serum immunoglobulin A (IgA) tissue transglutaminase (tTG) antibodies is useful because it offers adequate sensitivity and specificity at a 1997-07-01 2021-03-11 Dieterich W, Laag E, Schöpper H, et al.

TTGA : Celiac disease (gluten-sensitive enteropathy, celiac sprue) results from an immune-mediated inflammatory process following ingestion of wheat, rye, or barley proteins that occurs in genetically susceptible individuals. The inflammation in celiac disease occurs primarily in the mucosa of the small intestine, which leads to villous atrophy. Celiac disease is a maladaptation in which the ingestion of gluten-containing grains (e.
Celiac.com 02/08/2021 - Anti-tissue transglutaminase antibodies (tTG) are a strong indicator of celiac disease, but positive anti-tTG antibodies have also been reported in some non-celiac patients. A team of researchers recently set out to examine positive anti-tTG antibodies that are not related to gluten intake.
If so, several questions are of critical significance. How is TG2 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.

These autoantibodies are produced in the small-intestinal mucosa, and, during gluten consumption, they can also be detected in patients’ serum but disappear slowly from the circulation on a gluten-free diet.
