Obesity is associated with comorbidities including type 2 diabetes, chronic nonhealing wounds and psoriasis. Normally skin homeostasis and repair is regulated through the production of cytokines and growth factors derived from skin-resident cells including epidermal γδ T cells. However epidermal γδ T cells exhibit reduced proliferation and defective growth factor and cytokine production during obesity and type 2 diabetes. One of the genes modulated in epidermal γδ T cells during obesity and type 2 diabetes is CCR6, which is the receptor for CCL20. CCL20 is elevated in the skin during obesity and type 2 diabetes. Here we identify a subset of murine epidermal γδ T cells that expresses CCR6 in response to activation and post-wounding or psoriasis induction with imiquimod . We show that CCL20 stimulates epidermal γδ T cells to produce IL-17 suggesting CCR6 regulates the IL-17 axis as in dermal γδ T cells. Further, epidermal γδ T cells upregulate CCR6 and produce IL-17 during murine models of wound repair and psoriasis. Obesity increases CCR6 and IL-17 expression by epidermal γδ T cells during wound repair but has less of an effect during psoriasis. These findings have novel implications for the regulation of a specific population of IL-17-producing epidermal γδ T cells during skin damage and inflammation.
