T cell Immunoglobulin and Mucin domain 3 (TIM-3) is an Ig superfamily member expressed on IFNγ-secreting Th1 and Tc1 cells identified as a negative regulator of immune tolerance. TIM-3 is expressed by a subset of activated CD4+ T cells, and anti-CD3/anti-CD28 stimulation increases both the level of expression and the number of TIM-3+ T cells. In mice, TIM-3 is constitutively expressed on natural regulatory T cells and has been identified as a regulatory molecule of alloimmunity through its ability to modulate CD4+ T cell differentiation. Here, we examined TIM-3 expression on human Tregs to determine its role in T cell suppression. In contrast to mice, TIM-3 is not expressed on Tregs ex vivo but is upregulated after activation. While TIM-3+ Tregs with increased gene expression of lag3, ctla4 and foxp3 are highly efficient suppressors of effector T cells (Teff), TIM-3— Tregs poorly suppressed Th17 as compared to Th1 cells that was associated with decreased STAT-3 expression and phosphorylation with reduced gene expression of il10, ebi3, gzmB, prf1, il1Rα, and ccr6. Thus, our results suggest that TIM-3 expression on Tregs identifies a population highly effective in inhibiting pathogenic Th1 and Th17 responses.
