Purinergic signaling in healthy and diseased skin

Abstract

Adenosine 5'-triphosphate and adenosine receptors have been identified in adult and fetal keratinocytes, fibroblasts, melanocytes, mast cells, Langerhans cells, and Meissner's corpuscles, as well as in hair follicles, sweat glands, and smooth muscle and endothelial cells of skin vessels. Purinergic signaling is involved in skin pathology, including inflammation, wound healing, pain, psoriasis, scleroderma, warts, and skin cancer.
