Defects in dermal Vγ4 γ δ T cells result in delayed wound healing in diabetic mice.

The skin serves as a physical and chemical barrier to provide an initial line of defense against environmental threats; however, this function is impaired in diabetes. Vγ4 γ δ T cells in the dermis are an important part of the resident cutaneous immunosurveillance program, but these cells have yet to be explored in the context of diabetes. In this study, we observed that the impaired maintenance of dermal Vγ4 γ δ T cells is caused by reduced...
