ITGAE and acute kidney injury: Treg cells from both AKI contexts as well as unchallenged mice exhibited an overlap in the expression of the core tissue Treg cell signature (e.g., Areg, Itgae (encoding CD103), Ctla4, Tnfrsf4), whereas the expression of Il1rl1 and Klrg1 were largely confined to Treg cells from injured kidney.
