In critically ill patients GM-CSF has been trialled as a therapy for the immunosuppression of critical illness, and has shown promise restoring monocyte [23] and neutrophil [24] function, although the impact on patient outcomes is currently unclear and awaits larger studies. GM-CSF stimulates monocytes and macrophages to produce pro ...
In addition, after stimulation of β subunit mRNA levels coding α chain decrease and on the contrary expression of soluble α subunit is upregulated. Soluble GM-CSFRα then clutches free ligands with similar affinity as membrane receptor and prevents binding of GM-CSF to the cell surface. GM-CSFRα can be also cleaved off of the membrane receptor.

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.
Granulocyte colony-stimulating factor (G-CSF or GCSF), also known as colony-stimulating factor 3 (CSF 3), is a glycoprotein that stimulates the bone marrow to produce granulocytes and stem cells and release them into the bloodstream. [5] [6]
CFU-GM (Colony Forming Unit–Granulocyte–Macrophage [a]), also known as granulocyte–macrophage progenitor (GMP), is a colony forming unit. It is derived from CFU-GEMM. It is the precursor for monoblasts and myeloblasts. Production is stimulated by granulocyte macrophage colony-stimulating factor (GM-CSF).
Macrophage polarization is a process by which macrophages adopt different functional programs in response to the signals from their microenvironment. This ability is connected to their multiple roles in the organism: they are powerful effector cells of the innate immune system, but also important in removal of cellular debris, embryonic development and tissue repair.
The first signal is stimulation by M-CSF, GM-CSF, PGE2, adenosine, glucocorticoid, or apoptotic cells. [9] [18] The second signal can be stimulation with cytokines or toll-like receptor ligands. The first signal promotes the differentiation of monocytes to macrophages and the second signal promotes immunosuppressive functions. [8]
