What is IL-9?
IL-9 (Interleukin-9) is a cytokine secreted by Th9 cells, Th2 cells, mast cells, and type 2 innate lymphoid cells (ILC2s). It promotes mast cell growth, allergic inflammation, and mucosal immunity. IL-9 is a key marker for researchers studying allergy, asthma, and immunity to parasitic infection.
