Interleukin-9 (IL-9) is a proinflammatory cytokine historically believed to be involved in type 2 immune responses. However, recent evidence suggests IL-9 may be secreted by a distinct T Helper lineage called Th9. These cells can either be derived from Th2 cells with TGF-beta or differentiated directly from nave CD4+ T cells with TGF-beta and IL-4. IL-9 is a member of the common cytokine receptor gamma chain-dependent family of cytokines which also includes IL-2, IL-4, IL-7, IL-15 and IL-21. Its pleiotropic effects on Th2 lymphocytes, B lymphocytes, mast cells, eosinophils and gut and airway epithelial cells have implicated IL-9 in asthma and other allergy-related disorders.
