What is the difference between G CSF and GM-CSF?

G-CSF induces the appearance of colonies containing only granulocytes, while GM-CSF gave colonies containing both granulocytes and macrophages. Generation of G-CSF (genomic nomenclature: Csf3) and G-CSF Receptor (Csf3r) knockout mice confirmed that G-CSF critically drives granulopoiesis(7).

Is GM-CSF pro inflammatory?

Granulocyte macrophage colony stimulating factor (GM-CSF) is generally recognized as an inflammatory cytokine. Its inflammatory activity is primarily due its role as a growth and differentiation factor for granulocyte and macrophage populations.

What is GM-CSF protein?

GM-CSF is a cytokine that functions as a white blood cell growth factor. GM-CSF stimulates stem cells to produce granulocytes (neutrophils, eosinophils, and basophils) and monocytes.

What is the biological activity of GM-CSF?

The lymphokine granulocyte-macrophage colony-stimulating factor (GM-CSF) mediates the growth and differentiation of granulocytes and macrophages from bone marrow progenitors, and regulates biological functions expressed by mature cells of these lineages.

How quickly does G-CSF work?

This usually takes 5 to 7 days, although it can be longer. Long-acting G-CSF is given as a single injection the day after chemotherapy has completed. If you are having G-CSF before a stem cell transplant, you usually have your first injection 4 to 6 days before your stem cells are going to be collected.

What does G-CSF stand for?

G-CSF helps the bone marrow make more white blood cells. It is a type of colony-stimulating factor. Also called filgrastim and granulocyte colony-stimulating factor.

What stimulates GM-CSF?

GM-CSF is produced by various cell types including macrophages, mast cells, T cells, fibroblasts and endothelial cells 8, 9, mostly in response to immune activation and cytokines that mediate inflammation.

When do you start G-CSF?

G-CSF is usually started 24 hours or more after your chemotherapy finishes. You usually have it daily. Your doctor or pharmacist will tell you how many injections you need. Some types of G-CSF stay in the body for longer.

Can G-CSF cause leukemia?

A large majority of allogeneic hematopoietic stem cell donations are achieved using granulocyte-colony stimulating factor (G-CSF). G-CSF use has been associated with later development of myelodysplastic syndromes/acute myelogenous leukemia (MDS/AML) in several clinical circumstances.

When do you use G-CSF?

Filgrastim is used to stimulate the production of granulocytes (a type of white blood cell) in patients undergoing therapy that will cause low white blood cell counts. This medication is used to prevent infection and neutropenic (low white blood cells) fevers caused by chemotherapy. Filgrastim is a support medication.

What drug stimulates the production of white blood cells?

Why does G-CSF cause bone pain?

The precise underlying mechanism behind the bone pain is unknown; it may be caused by expansion of bone marrow resulting from increases in hematopoietic progenitor cells and histamines as part of an immunologic response brought on by G-CSF. Histamine release has been implicated in bone marrow edema and pain.

How are M-CSF and GM-CSFs related?

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 is the function of GM CSF in white blood cells?

GM-CSF is a monomeric glycoprotein that functions as a cytokine — it is a white blood cell growth factor. GM-CSF stimulates stem cells to produce granulocytes ( neutrophils, eosinophils, and basophils) and monocytes. Monocytes exit the circulation and migrate into tissue, whereupon they mature into macrophages and dendritic cells.

Why is GM CSF known as colony stimulating factor?

GM-CSF was originally identified as a colony stimulating factor (CSF) because of its ability to induce granulocyte and macrophage populations from precursor cells.

What are the roles of GM-CSF in synovial?

Reynolds et al. have indicated that CD4 + T cells are the primary source of GM-CSF in synovial and that GM-CSF production by these cells is related to Th1 cell activation and IL-15. They have also shown that CD14 + monocyte differentiation into CD1c + infDCs is dependent on GM-CSF production by CD4 + T cells.

What is the difference between G CSF and GM-CSF? G-CSF induces the appearance of colonies containing only granulocytes, while GM-CSF gave colonies containing both granulocytes and macrophages.
