| umls-concept:C0085424 | skos:definition | MSH: A multifunctional cytokine secreted by primarily by activated TH2 CELLS that may play a role as a regulator of allergic INFLAMMATION. It has been shown to enhance the growth and CELL DIFFERENTIATION of MAST CELLS, and can act on a variety of other immune cells.,CSP: produced by T cells and macrophages; acts as a growth factor for some T cell populations in vitro.,NCI: Human interleukin-9 protein (144 aa 16 kDa precursor) is encoded by the human interleukin-9 (IL9) gene.
