Is gliadin mispresented to the immune system in coeliac disease? A hypothesis

Abstract

The primary pathogenic trigger in coeliac disease (CD) is still unknown. We present the hypothesis that in CD the enterocytes could metabolize gliadin through an immunogenic pathway instead of a tolerogenic one. The result of this abnormal presentation of gliadin to the immune system would be the activation of lamina propria T cells, followed by the onset of enteropathy.
