Vγ2Vδ2 T cells in human peripheral blood recognize phosphoantigen and play important roles in host defense and immunoregulation. The TCR is required for Vγ2Vδ2 T cell responses to phosphoantigen, but less is known about soluble or cell-associated costimulatory molecules. In this study, we show that human Vγ2Vδ2 T cell responses to phosphoantigen, including activation, proliferation, cytokine production, and tumor cell cytotoxicity, require TNF-α binding to its receptor, with a preference for TNFR2. Because stimulated Vγ2Vδ2 cells also produce TNF-α, this may be a positive control mechanism to sustain the response. Impaired proliferation in the presence of TNF-α or TNFR blocking agents was partially rescued by a TLR2 agonist, Pam3Cys. Our studies demonstrate that TNF-α plays a critical role in regulating human Vγ2Vδ2 T cell immune responses.
