Interleukin-9 (IL-9) is a heavily glycosylated cytokine with a 14 kDa peptide backbone that is secreted by CD4+ Th2 cells. It supports the growth of multiple hematopoietic cell types including Th cells, germinal center B cells, macrophages, mast cells, neutrophils, megakaryocytes, and erythrocytes.

IL-9 exerts its biological effects through a receptor complex composed of IL-9 R and the common gamma chain; which activates different signal transducer and activator (STAT) proteins and thus connects this cytokine to various biological processes. The gene encoding this cytokine has been identified as a candidate gene for asthma. Genetic studies on a mouse model of asthma demonstrated that this cytokine is a determining factor in the pathogenesis of bronchial hyperresponsiveness. Interleukin-9 has also shown to inhibit melanoma growth in mice.
