What is the purpose of GM-CSF?

A substance that helps make more white blood cells, especially granulocytes, macrophages, and cells that become platelets. It is a cytokine that is a type of hematopoietic (blood-forming) agent. Also called granulocyte-macrophage colony-stimulating factor and sargramostim.

What is a cytokine GM-CSF?

Function. 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.

How is GM-CSF administered?

The GM-CSF was administered subcutaneously in 28-day cycles, such that a dose of 125 microg/m2 was delivered daily for 14 days followed by 14 days rest. Treatment cycles continued for 3 years or until disease recurrence, which could not be surgically excised.

Is GM-CSF pro or anti inflammatory?

GM-CSF was first characterized as a pro-inflammatory cytokine due to its ability to stimulate plasminogen-dependent fibrinolysis activity in mouse macrophages (Hamilton and others 1980).

What does GM-CSF do to dendritic cells?

GM-CSF (Csf-2) is a critical cytokine for the in vitro generation of dendritic cells (DCs) and is thought to control the development of inflammatory DCs and resident CD103+ DCs in some tissues.

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.

Is GM-CSF a growth factor?

Granulocyte-macrophage colony-stimulating factor (GM-CSF) was first described as a growth factor that induces the differentiation and proliferation of myeloid progenitors in the bone marrow.

Is GM-CSF pro inflammatory cytokine?

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 cells release GM-CSF?

GM-CSF is produced by multiple cell types such as activated T cells, B cells, macrophages, monocytes, mast cells, vascular endothelial cells, and fibroblasts (2).

Can GM-CSF be used as a standard therapy for sepsis?

The applicability of GM-CSF as a standard therapy for generalized sepsis is still largely understudied; however, small-scale studies available have demonstrated some improved recovery from infection, decreased hospital length of stay, decreased days requiring mechanical ventilation, and decreased medical costs.

Can csf2-deficient human glioma cells be transplanted to the human brain?

CSF2-deficient human glioma cells encapsulated in cell-impermeable hollow fibres and transplanted to mouse brains, failed to attract microglia, but stimulated astrocyte recruitment. CSF2-depleted gliomas were smaller, attracted less microglia and macrophages, and provided survival benefit in tumour-bearing mice.

What is csf2/granulocyte macrophage colony stimulating factor?

How does tumour-derived CSF2 affect the brain microenvironment?

Tumour-derived CSF2 controls recruitment of microglia and macrophages and contributes to tumour progression To study the impact of tumour-derived CSF2 on the brain microenvironment, we encapsulated human U87 and LN18 glioma cells into hollow fibres (HF) and transplanted them into the brains of immunocompetent mice.
