Interleukin 9 is a [[cytokine]] produced by [[T-cells]] and specifically by [[CD4+ helper cells]] that acts as a regulator of a variety of [[hematopoietic cell]]s. This cytokine stimulates [[cell proliferation]] and prevents [[apoptosis]]. It functions through the [[interleukin-9 receptor]] (IL9R), which activates different signal transducer and activator ([[STAT protein|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]].<ref name="entrez" />

Template:PBB Interleukin 9, also known as IL-9, is a cytokine (cell signalling molecule) belonging to the group of interleukins.[1]

Function

The protein encoded by this gene is a cytokine produced by T-cells and specifically by CD4+ helper cells that acts as a regulator of a variety of hematopoietic cells. 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.[1]

Interleukin-9 has also shown to inhibit melanoma growth in mice.[2]
