Nitric oxide (NO) is a free radical with pleiotropic functions. We have shown earlier that NO induces a population of CD4+CD25+Foxp3− regulatory T cells (NO-Tregs) which suppress the functions of CD4+CD25− effector T cells in vitro and in vivo. We report here an unexpected finding that NO-Tregs suppressed Th17 but not Th1 cell differentiation and function. In contrast, natural Tregs (nTregs), which suppressed Th1 cells, failed to suppress Th17 cells. Consistent with this observation, NO-Tregs inhibited the expression of RORγt but not T-bet, whereas nTregs suppressed T-bet, but not RORγt expression. The NO-Tregs-mediated suppression of Th17 was partially cell-contact-dependent and was associated with IL-10. In vivo, adoptively transferred NO-Tregs potently attenuated experimental autoimmune encephalomyelitis (EAE). The disease suppression was accompanied by a reduction of Th17, but not Th1 cells in the draining lymph nodes, and decrease in the production of IL-17, but increase in IL-10 synthesis. Our results therefore demonstrate the differential suppressive function between NO-Tregs and nTregs and indicate specialization of the regulatory mechanism of the immune system.
