Description - Human interleukin 9 (HP40, P40; Gene ID: 3578) is a pleiotropic cytokine that has effects on both myeloid and lymphoid cells. It is produced by at least 2 subtypes of T helper cells. Th2 cells were the first cell type that was recognized to produce IL-9. Recently Th17 T cells have been found to secrete IL-9. Naïve T cells treated with TGF-β and IL-4 differentiate into the TH9 subtype. IL-9 binds to its cognate receptor IL9R, also known as CD129, which activates the JAK/STAT network.

Disease Research Focus - Allergen-induced inflammation, extracellular parasites, asthma, and cancer.

Application Area - Inflammation, cytokines, and chemokines
