Title: Interleukin-3
Additional Names: Multipotent colony stimulating factor; IL-3; multi-CSF
Literature References: Hematopoietic growth factor that promotes the survival, differentiation and proliferation of multipotent hematopoietic stem cells and of committed progenitor cells of the megakaryocyte, granulocyte-macrophage, erythroid, eosinophil, basophil and mast cell lineages. Enhances thrombopoiesis, phagocytosis, antibody-mediated cellular cytotoxicity and eosinophil metabolism. Species-specific, variably glycosylated peptide; human: 14-28 kDa, 133 amino acids; murine: 22-32 kDa, 140 amino acids. Produced primarily by activated T-lymphocytes; also by natural killer cells and mast cells. Undetectable in normal serum, postulated to be involved in the immune response.
