WebActivation of TGF-β by dendritic cells (DCs) expressing αvβ8 integrin is essential for the generation of intestinal regulatory T cells (Tregs) that in turn promote tolerance to intestinal Ags. We have recently shown that αvβ8 integrin is preferentially expressed by CD103(+) DCs and confers their ability to activate TGF-β and generate Tregs.
