Unlike conventional T cells, which are exported from the thymus as naive cells and acquire effector functions upon antigen encounter in the periphery, a subset of ?? T cells differentiates into effectors that produce IL-17 within the fetal thymus. We demonstrate here that intrathymic development of the naturally occurring IL-17-producing ?? T cells is independent of STAT3 and partly dependent on ROR?t. Comparative gene-expression analysis identified Hes1, one of the basic helix-loop-helix proteins involved in Notch signaling, as a factor specifically expressed in IL-17-producing ?? T cells. Hes1 is critically involved in the development of IL-17-producing ?? T cells, as evidenced by their severe decrease in the thymi of Hes1-deficient fetal mice. Delta-like 4 (Dll4)-expressing stromal cells support the development of IL-17-producing ?? T cells in vitro. In addition, conditional Hes1 ablation in peripheral ?? T cells decreases their IL-17 production but not their IFN-? production. These results reveal a unique differentiation pathway of IL-17-producing ?? T cells.
