Description
Interleukin-31 (IL-31) is a T-cell cytokine, which is preferentially produced by type 2 helper T cells. The structure of IL-31 places it in the IL-6 family of cytokines. IL-31 signals via a receptor complex that is composed of IL-31 receptor A and oncostatin M receptor subunits. IL-31 is believed to play a role in inflammation of the skin.1 IL-31 represents a novel target for antipruritic drug development.2
