Tumor Necrosis Factor Alpha (TNFα): Definition & Importance. Granulocyte-macrophage colony-stimulating factor (GM-CSF) is a monomeric glycoprotein present in human blood and a number of other types of tissue. It is a key regulator of macrophage function that can stimulate cells from many different sources to release interferon and other cytokines, or to participate in mechanisms that cause other cells to release these same proteins. It was first isolated by Schachter and Wollman in 1975.
Granulocyte-macrophage colony stimulation factor (GM-CSF) is a cytokine often associated with the immune system. It increases macrophage activation and then mobilizes neutrophils from their resting state. GM-CSF also mediates the migration of eosinophils to remote sites of inflammation.
GM CSF structure is a natural messenger that communicates between the immune cells, activates and regulates their functions. Recent studies have shown that GM-CSF deficiency may contribute to serious diseases, such as MS. Moreover, in addition to its role in inflammation, GM-CSF also enhances wound healing. While GM-CSF has been used in therapeutic applications since the 1950s it is only recently that it has shown promise as a novel drug delivery vehicle for this drug. We believe that this is a very promising drug application and treatment for multiple diseases and conditions.
The Stem Cell Factor Structure(tm) from GeneSource is a patented, highly concentrated liquid culture-derived GM-CSF in a ready-to-use solution. GM-CSF is extracted from human amnion cells and contains both human and mouse GM-CSF genes. It produces six different subtypes of immobilized GM-CSF (h1, h2, eozin, rhizhin, diap, gmcsf). Stem Cell Factor Structure has been clinically tested to be superior to the commercially available product called GM-CSF Concentrate derived from bone marrow stroma cultures (BMCSF). It appears to have better tissue penetrability and the potential to produce a more proportional response compared to other commercial products. Additionally, Stem Cell Factor Structure has shown superior productivity in generating Human Immunoglobulin (Ig)G1 and IgG4 antibodies.
What is tumor necrosis factor alpha: Tumor necrosis factor-alpha, TNFα, is a human cytokine associated with systemic inflammation. Primarily, activated macrophages produce TNFα, but other cell types such as natural killer cells and neutrophils can also produce TNFα. These cells produce TNFα as a stable 233 amino acid long homotrimer protein.
Tumor necrosis factor alpha is a human cytokine associated with systemic inflammation and an integral component of the acute phase reaction. TNFα belongs to the TNF superfamily that comprises several transmembrane proteins. The human tumor necrosis factor alpha primarily regulates the immune cells. Tumor Necrosis Factor-alpha (or TNFα) is an important cytokine in our immune system. Produced by macrophages, it plays a role in systemic inflammation and the acute phase response. While several cells types can produce this cytokine, mostly natural killer cells, mast cells, T helper cells, eosinophils, and neutrophils create it.
Tumor necrosis factor-alpha, also known as TNFα or cachexin, is a cell signaling protein (cytokine) involved in systemic inflammation. It is produced by activated macrophages, which cause death of tumor cells. There are two types: the membrane-bound form and the soluble form. The soluble form gets released into the extracellular space and has a half-life of less than an hour. TNFα can be released either as a transmembrane trimer or cleaved and secreted as a soluble trimer.
