Mechanisms of epithelial translocation of the α₂-gliadin-33mer in coeliac sprue

Abstract

Epithelial translocation of the alpha(2)-gliadin-33mer occurs by transcytosis after partial degradation through a rab5 endocytosis compartment and is regulated by interferon-gamma. Uptake of the 33mer is higher in untreated coeliac disease than in controls and coeliac disease patients on a gluten-free diet.
