GM-CSF Recombinant Protein

Background:

Human GM-CSF is a 24 kDa glycoprotein produced by a variety of cell types, including T and B lymphocytes, macrophages, keratinocytes, eosinophils, neutrophils, and endothelial cells in response to cytokine or inflammatory stimuli. GM-CSF was initially identified on the basis of its capacity to stimulate the clonal proliferation of myeloid precursors in vitro. GM-CSF promotes a Th1 biased immune response, allergic inflammation, and the development of autoimmunity. GM-CSF are particularly effective as antitumor vaccines. GM-CSF regulates multiple biological activities through activation of the GM-CSF receptor (GMCSFR), a member of the type I cytokine receptor group comprising alpha and beta subunits.
