Interleukin-31 (IL-31) is a cytokine with a molecular weight of 15.65 kDa, consisting of 141 amino acid residues. Primarily secreted by Th2 cells, IL-31 binds to a receptor known as IL-31RA. Upon binding to IL-31RA, it activates multiple signaling pathways, including the MAPK, PI3K/AKT, and JAK/STAT pathways. It plays a crucial role in regulating various biological functions, such as cell proliferation, hematopoiesis, cytokine induction, inflammation, and immune responses. Additionally, it responds to antigens by promoting cell-mediated immunity.
