The Regulatory T Cell: Jack-Of-All-Trades

Foxp3(+) regulatory T (Treg) cells suppress auto-reactive and inflammatory T cells to maintain immune homeostasis. In a recent study, Rudensky and colleagues demonstrate the ability of Treg cells to facilitate tissue repair, a non-canonical Treg cell function accomplished by amphiregulin and mediated by cytokines interleukin (IL)-18 and IL-33.
