BACKGROUND

Interleukin 9, also known as IL-9, is a cytokine (cell signaling molecule) belonging to the group of interleukins. IL-9 is a multifunctional cytokine secreted by TH2 lymphocytes. Interleukin-9 is reported to play important roles in innate and adaptive immunity in extrarenal inflammatory diseases. The tolerogenic cytokine IL9 promotes T regulatory cell function and allergic airway inflammation. Eliminating endogenous IL9 enabled sensitization of host T cells to tumors, leading to their early rejection without the requirement of vaccines or immunomodulatory therapies. IL-9 predominantly produced by TH17 cells synergizes with TGF-β1 to differentiate naive CD4+ T cells into TH17 cells, while IL-9 secretion by TH17 cells is regulated by IL-23. IL-9 has been demonstrated to be involved in several diseases, such as cancer, autoimmunity and other pathogen-mediated immune-regulated diseases.
