title: Cutaneous gammadelta T cells-selecting a destination and asking for directions in the thymus.
abstract: T cell receptor-defined subsets of gammadelta T cells differentially localize in cutaneous, intestinal, or reproductive epithelium. In this issue of Immunity, Xiong et al. show that murine Vgamma3+ T cells undergo TCR-dependent selection in the fetal thymus that drives expression of a cutaneous homing receptor.
