Abstract

Innate gammadelta T cells function in the early phase of immune responses. Although innate gammadelta T cells have often been studied as one homogenous population, they can be functionally classified into effector subsets on the basis of the production of signature cytokines, analogous to adaptive helper T cell subsets. However, unlike the function of adaptive T cells, gammadelta effector T cell function correlates with genomically encoded T cell antigen receptor (TCR) chains, which suggests that clonal TCR selection is not the main determinant of the differentiation of gammadelta effector cells. A high-resolution transcriptome analysis of all emergent gammadelta thymocyte subsets segregated on the basis of use of the TCR gamma-chain or delta-chain indicated the existence of three separate subtypes of gammadelta effector cells in the thymus. The immature gammadelta subsets were distinguished by unique transcription-factor modules that program effector function.
