Background
Granulocyte-macrophage colony-stimulating factor (GM-CSF), also known as colony stimulating factor 2 (CSF2), is a cytokine belonging to the GM-CSF family. GM-CSF is secreted by a variety of cell types including macrophages, T cells, mast cells, endothelial cells and fibroblasts. GM-CSF stimulates the growth and differentiation of hematopoietic precursor cells from various lineages, including granulocytes, macrophages, eosinophils and erythrocytes.
GM-CSF exerts its biological effects through a heterodimeric receptor complex composed of GM-CSF Rα/CD116 and the signal transducing common β chain (CD131) which is also a component of the high affinity receptors for IL-3 and IL-5. As an important modulator of the immune/inflammatory cascade, GM-CSF promotes Th1 biased immune response, angiogenesis, allergic inflammation, and the development of autoimmunity. GM-CSF has been manufactured by recombinant DNA technology and marketed as a protein therapeutic reagent to stimulate the production of white blood cells and thus prevent neutropenia following chemotherapy.
