Granulocyte-macrophage colony-stimulating factor (GM-CSF) is a monomeric glycoprotein that acts as a cytokine in humans. Macrophages, mast cells, T cells, endothelial cells, fibroblasts, and natural killer cells, secrete GM-CSF. Although the release of human GM-CSF is local, it can act in a paracrine fashion to recruit circulating monocytes, lymphocytes, and neutrophils to enhance host defense mechanisms. Unlike colony stimulating factor 3 that specializing in the proliferation and maturation of neutrophils, GM-CSF stimulates a spectrum of cell types, especially eosinophils and macrophages. Granulocyte macrophage colony-stimulating factor GM-CSF is a cytokine that acts as a monomeric glycoprotein in humans. Macrophages, mast cells, T-cells, endothelial cells, fibroblasts and natural killer cells secrete GM-CSF.
Granulocyte-macrophage colony-stimulating factor (GM-CSF) is a monomeric glycoprotein that acts as a cytokine in humans. GM-CSF modulates the proliferation, differentiation, and function of macrophages. It can also stimulate the production of IL-3, G-CSF, TNF-α and other soluble factors by macrophages. In addition, GM-CSF plays an essential role in regulating hematopoiesis.
Granulocyte macrophage colony stimulating factor, known as gm csf immunotherapy GM-CSF, is a monomeric glycoprotein secreted by cells of the immune system. It acts to induce proliferation and differentiation of neutrophils, macrophages, eosinophils and mast cells. Its main role is to stimulate production of infection-fighting white blood cells and their release from the bone marrow into the bloodstream. Most selectively targeted biologics are proteins produced by recombinant DNA technology in bacteria or yeast.
Interferon-gamma or IFN γ is a human protein encoded by the IFNG gene. The biologically active molecule of IFN γ is a dimerized soluble protein made up of two monomers. IFN γ is the sole member of the type II interferons group. It binds to the IFN-γ receptor complex, which contains two subunits, IFNGR1 and IFNGR2, to produce its cellular signal. One of its jobs is to inhibit viral replication to fight against bacteria and modulate the immune system.
Immune interferon, or interferon-gamma, is a polypeptide protein encoded by the IFNG gene. It is made up of two monomers that form a noncovalent homodimer in solution (Biochemistry 23: 3525-3533,1984). This protein is an interlocking anti-parallel form of two monomers. One molecule of IFN γ binds to IFNGR1 to another molecule of IFN γ by disulphide bridge between the carboxylic acid residues and the amino terminal portions between IFNGR1 and the first monomer. Besides binding to IFNGR1, IFN γ also binds to an IFN-γ receptor complex consisting of the dimeric receptor molecules: IFNGR2 and CD40. This dimeric receptor occurs as a surface recognized on activated T cells, NK cells, and NKT cells. Thus, type II interferons utilize 2 distinct receptors as well as these factors alone or with other cytokines play critical roles in innate and adaptive immunity.
What is interferon gamma: Interferon-gamma or IFN γ is a protein composed of two identical subunits that regulates the immune response in the human body. As type II interferons, they play a crucial role in innate and adaptive immunity. Interferon-gamma along with the receptor proteins IFNGR1 and IFNGR2 make up the IFN-γ receptor complex. This interferon activates immune cells by binding to receptors on the cell surface, starting a sequence of reactions that leads targeting phagocytosis of target cells such as virus infected cells or tumor cells.
