Intestinal epithelial cell-derived integrin αβ6 plays an important role in the induction of regulatory T cells and inhibits an antigen-specific Th2 response

Toleroge nic DCs and Tregs are believed to play a critical role in oral tolerance. However, the mechanisms of the generation of tolerogenic DCs and activation of Tregs in the gut remain poorly understood. This study aims to dissect the molecular mechanisms by which IECs and protein antigen induce functional tolerogenic DCs and Tregs. Expression of αvβ6 by gut epithelial cell-derived exosomes, its coupling with food antigen, and their …
