Recently, a function has been assigned to a previously identified orphan chemokine receptor, GPR-2. This receptor, also called CCR10, binds with monocyte chemoattractant protein (MCP)-1, MCP-3 and MIP-1 beta. CCR10 is expressed by melanocytes, dermal fibroblasts, dermal microvascular endothelial cells, T cells as well as in skin-derived Langerhans cells. CCR10 may play a role in both skin homeostasis as well as a potential role in inflammatory responses.
