Interleukin 9, also known as IL-9, is a cytokine (cell signalling molecule) belonging to the group of interleukins.^[5]

Function

Il-9 is a cytokine secreted by CD4+ helper cells that acts as a regulator of a variety of hematopoietic cells.^[6] This cytokine stimulates cell proliferation and prevents apoptosis. It functions through the interleukin-9 receptor (IL9R), 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.^[5]

Interleukin-9 has also shown to inhibit melanoma growth in mice.^[7]
