Human γδ T cells expressing the Vγ2Vδ2 TCR play important roles in immune responses to microbial pathogens by monitoring prenyl pyrophosphate isoprenoid metabolites. Most adult Vγ2Vδ2 cells are memory cytotoxic cells that produce IFN-γ. Recently, murine γδ T cells were found to be major sources of IL-17A in anti-microbial and autoimmune responses. To determine if primate γδ T cells play similar roles, we characterized IL-17A and IL-22 production by Vγ2Vδ2 cells. IL-17A-producing memory Vγ2Vδ2 cells exist at low but significant frequencies in adult humans (1:2,762 T cells) and at even higher frequencies in adult rhesus macaques. Higher levels of Vγ2Vδ2 cells produce IL-22 (1:1,864 T cells) although few produce both IL-17A and IL-22. Unlike adult humans where many IL-17A+ Vγ2Vδ2 cells also produce IFN-γ (Tγδ1/17), the majority of adult macaques IL-17A+ Vδ2 cells (Tγδ17) do not produce IFN-γ. To define the cytokine requirements for Tγδ17 cells, we stimulated human neonatal Vγ2Vδ2 cells with the bacterial antigen, HMBPP, and various cytokines and mAbs in vitro. We find that IL-6, IL-1β, and TGF-β are required to generate Tγδ17 cells in neonates whereas Tγδ1/17 cells additionally required IL-23. In adults, memory Tγδ1/17 and Tγδ17 cells required IL-23, IL-1β, and TGF-β but not IL-6. IL-22-producing cells showed similar requirements. Both neonatal and adult IL-17A+ Vγ2Vδ2 cells expressed elevated levels of RORγt. Our data suggest that, like Th17 αβ T cells, Vγ2Vδ2 T cells can be polarized into Tγδ17 and Tγδ1/17 populations with distinct cytokine requirements for their initial polarization and later maintenance.
