NKG2D-dependent activation of dendritic epidermal T cells in contact hypersensitivity.

ABSTRACT: The interaction between keratinocytes (KCs) and skin-resident immune cells has an important role in induction of contact hypersensitivity. A specific subset of γδ T cells termed dendritic epidermal T cells (DETCs) are located in mouse epidermis, and we have recently shown that DETCs become activated and produce IL-17 in an IL-1β-dependent manner during contact hypersensitivity. Various receptors on DETCs, including NKG2D, are involved in DETC responses against tumors and during wound healing. The ligands for NKG2D (NKG2DL) are stress-induced proteins such as mouse UL16-binding protein-like transcript 1 (Mult-1), histocompatibility 60 (H60), and retinoic acid early inducible-1 (Rae-1) in mice and major histocompatibility complex (MHC) class I-chain-related A (MICA), MHC class I-chain-relate
