Hintergrund von IL-9 Antikörper

Interleukin-9, also known as Cytokine P40, T-cell growth factor P40, IL-9 and IL9, is a secreted protein which belongs to theIL-7 / IL-9 family. Interleukin-9 / IL-9 is a cytokine produced by T-cells and specifically by CD4+ helper cells that acts as a regulator of a variety of hematopoietic cells. Interleukin-9 / IL-9 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. It is a T (H)2 cell-derived cytokine that might be involved in the pathophysiology of allergic diseases. IL-9 is specifically upregulated after local allergen challenge in the lungs of atopic asthmatic patients. Lymphocytes are the major cellular source of IL-9. The increased expression and its correlation with eosinophil numbers suggest a potential role for IL-9 in the late phase of the allergic response.
