Human regulatory T cells (Tregs) are essential for the maintenance of immune tolerance. However, the mechanisms they use to mediate suppression remain controversial. Although IL-35 has been shown to play an important role in Treg-mediated suppression in mice, recent studies have questioned its relevance in human Tregs. Here we show that human Tregs express and require IL-35 for maximal suppressive capacity. Substantial up-regulation of EBI3 and IL12A, but not IL10 and TGFB was observed in activated human Tregs compared with Tconv. Contact-independent Treg-mediated suppression was IL-35 dependent and did not require IL-10 or TGF-β. Lastly, human Treg-mediated suppression led to the conversion of the suppressed Tconv into iTr35 cells, IL-35 induced iTreg population, in an IL-35-dependent manner. Thus, IL-35 contributes to human Treg-mediated suppression, and its conversion of suppressed target Tconv into iTr35 cells may contribute to infectious tolerance.
