What is the difference between M-CSF and GM-CSF?
M-CSF exhibits a mostly homeostatic expression pattern, whereas GM-CSF is a product of cells activated during inflammatory or pathologic conditions. Accordingly, M-CSF regulates the numbers of various tissue macrophage and monocyte populations without altering their “activation” status.
What does M-CSF stand for?
macrophage colony-stimulating factor
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.
What produces M-CSF?
M-CSF is produced by osteoblasts and osteoblast precursors, but large amounts of M-CSF are also produced by osteocytes. M-CSF is present in two distinct biologically active forms, a membrane-bound and a secreted form, that result from alternative splicing of the CSF1 gene.
How is GM-CSF activated?
While various types of T cells produce GM-CSF upon activation, it is mostly a transient event. During viral infection, both CD4+ and CD8+ T cells are known to produce GM-CSF. Interestingly, CD4+ helper T cells of both the Th1 and Th2 type have been shown to secrete GM-CSF.
What is the difference between filgrastim and pegfilgrastim?
Treatment regimens differ slightly: filgrastim is administered daily for up to a maximum of 14 days, either subcutaneously or intravenously, whereas pegfilgrastim treatment involves a single SC dose per chemotherapy cycle with no restrictions to every 14-day cycles only.
Is G-CSF the same as filgrastim?
Granulocyte – colony stimulating factor (G-CSF) is another name for filgrastim. In some cases, health care professionals may use the trade name Neupogen, Granix or Zarxio when referring to the generic drug name filgrastim.
Is M-CSF a cytokine?
Macrophage colony-stimulating factor (M-CSF) is a cytokine found in the brain whose receptor is expressed by microglia. Previous studies suggest a critical role for M-CSF in brain development and normal functioning as well as in several disease processes involving neuroinflammation.
How does a colony-stimulating factors work?
Colony-stimulating factors (CSFs) are secreted glycoproteins that bind to receptor proteins on the surfaces of hemopoietic stem cells, thereby activating intracellular signaling pathways that can cause the cells to proliferate and differentiate into a specific kind of blood cell (usually white blood cells.
