Background

Interleukin-9 (IL-9) is a heavily glycosylated cytokine with a 14 kDa peptide backbone that is secreted by CD4⁺ Th2 cells. It supports the growth of multiple hematopoietic cell types including Th cells, germinal center B cells, macrophages, mast cells, neutrophils, megakaryocytes, and erythrocytes. IL-9 exerts its biological effects through a receptor complex composed of IL-9 R and the common gamma chain. Mature human IL-9 shares 57% amino acid sequence identity with mouse and rat IL-9.

Limitations
