Mouse Interleukin 9 (IL-9) is a 144 amino acid, 16.1 kD member of the TH2 cytokine family. Originally identified as a mast cell growth factor, IL-9 has been identified to promote IL-6 and protease production in mast cells that in turn contribute to the severity of hypersensitivity disorders. These characteristics, among others, have made IL-9 a molecule of interest in studies of hypersensitivity disorders, such as asthma.
