The colony stimulating factor 1 (CSF1), also known as macrophage colony-stimulating factor (M-CSF), is a secreted cytokine which causes hematopoietic stem cells to differentiate into macrophages or other related cell types. Eukaryotic cells also produce M-CSF in order to combat intercellular viral infection.
Colony stimulating factor 1 receptor (CSF1R), also known as macrophage colony-stimulating factor receptor (M-CSFR), and CD115 (Cluster of Differentiation 115), is a cell-surface protein encoded by the human CSF1R gene (known also as c-FMS).
Granulocyte-macrophage colony-stimulating factor (GM-CSF), also known as colony-stimulating factor 2 (CSF2), is a monomeric glycoprotein secreted by macrophages, T cells, mast cells, natural killer cells, endothelial cells and fibroblasts that functions as a cytokine.
The name "colony-stimulating factors" comes from the method by which they were discovered. Hematopoietic stem cells were cultured (see cell culture) on a so-called semisolid matrix, which prevents cells from moving around, so that, if a single cell starts proliferating, all of the cells derived from it will remain clustered around the spot in the matrix where the first cell was originally located.
The granulocyte-macrophage colony-stimulating factor receptor is a heterodimer composed of at least two different subunits; an α chain, and a β chain which is also present in the receptors for IL-3 and IL-5. The α subunit contains a binding site for granulocyte macrophage colony-stimulating factor, but associates with the ligand only with ...
Classically activated macrophages (M1) were named by G. B. Mackaness in the 1960s. [20] M1-activation in vitro is evoked by treatment with TLR ligands such as bacterial lipopolysaccharide (LPS) - typical for Gram-negative bacteria and lipoteichoic acid (LTA) - typical for Gram-positive bacteria, granulocyte-macrophage colony-stimulating factor (GM-CSF) or combination of LPS and interferon ...
a cell-surface protein encoded, in humans, by the CSF1R gene. Also known as colony stimulating factor 1 receptor (CSF1R) and/or as macrophage colony-stimulating factor receptor (M-CSFR). It is a receptor, known to be expressed on monocytes and macrophages, for a cytokine called colony stimulating factor 1 (CSF1) and also interleukin 34 (IL34 ...
One notable example is the granulocyte macrophage colony-stimulating factor. The goal of this stimulated immune response is usually to help the body have a stronger immune system response in order to improve outcomes in the case of an infection or cancer malignancy.
