anti- IL31 antibody

Background

Interleukin 31 (IL31) is a cytokine belonging to the IL-6 cytokine family that plays a central role in the regulation of immune responses and is heavily implicated in inflammatory processes, particularly in chronic pruritic (itching) skin disorders. IL-31 is primarily produced by activated T helper 2 (Th2) cells, a subset of T cells involved in allergic responses and the regulation of immune responses to extracellular pathogens. IL-31 was discovered as a cytokine that can link the immune system with the nervous system, particularly in the skin, where it triggers pruritus and inflammatory responses. The IL-31 receptor is widely expressed, being found on keratinocytes, fibroblasts, epithelial cells, and immune cells, which suggests its involvement in skin and tissue homeostasis
