Abstract

Vav1 is a guanine nucleotide exchange factor essential in the development and function of αβ lineage T cells. Here we report that in contrast to profound effects on pre-TCR- or αβ TCR-dependent events in thymocyte development, Vav1 deficiency has no detectable effect on the development of γδ T cells. Strikingly, however, these γδ T cells are markedly deficient in signaling through the γδ TCR, as evidenced by a lack of proliferation and cytokine production in response to stimulation with anti-γδ TCR antibodies. We propose that Vav1 has a unique and non-redundant role in the initiation of signaling downstream of the γδ TCR in lymphocytes.
