Is it true coeliacs do not digest gliadin ?. Degradation pattern of gliadin in coeliac disease small intestinal mucosa

Prolyl-endopeptidase supplementation has been proposed to favour gliadin degradation as an alternative treatment for coeliac disease (CD), although the real usefulness of this therapy in vivo is still under discussion. 1 However, our data point to alternative treatments aiming to modify the intestinal microbiota in patients with CD by the use of probiotics and/or prebiotics. We propose that the induction of gliadin proteolysis in the human gut might not be the solution but the origin of CD
