a General rules governing immunogenicity. b Gliadin-derived peptides that act as an adjuvant (P31-P43) or as an immunogen (P57–68). Note that innate immune reactions are required for full cognate immune responses. This is exemplified by the activation of transglutaminase-2 (TGM2), downstream of the inhibition of cystic fibrosis transmembrane receptor (CFTR), as well as local inflammation that perturbs tissue homeostasis, increases intestinal permeability, and attracts immune cells, thus enabling to launch a TH1 immune response against deamidated P57–68
