Cutting Edge: Identification of a Motile IL-17–Producing γδ T Cell Population in the Dermis

Abstract excerpt

Dendritic epidermal T cells (DETCs) are a well-studied population of γδ T cells that play important roles in wound repair. In this study, we characterize a second major population of γδ T cells in the skin that is present in the dermis. In contrast to DETCs, these Vγ5-negative cells are IL-7R(hi)CCR6(hi) retinoic acid-related orphan receptor γt(+) and are precommitted to IL-17 production. Dermal γδ T cells fail...
