  • Title: Granulocyte-macrophage colony-stimulating factor: pleiotropic cytokine with potential clinical usefulness.
    Author: Ruef C, Coleman DL.
    Journal: Rev Infect Dis; 1990; 12(1):41-62. PubMed ID: 2405468.
    Abstract:
    Granulocyte-macrophage colony-stimulating factor (GM-CSF) is a 23-kDa glycoprotein with remarkably diverse effects on immune and nonimmune cells. GM-CSF induces differentiation of granulocyte, macrophage, and eosinophil precursor cells. Proliferation of monocyte-macrophages, T lymphocytes, keratinocytes, and endothelial cells is also stimulated by GM-CSF. In addition, GM-CSF alters the functional properties of mature granulocytes, macrophages, eosinophils, and basophils. GM-CSF is produced by T lymphocytes, macrophages, and several cell types in extramedullary sites, where it may act in a paracrine manner to regulate the local response to antigenic challenge. Clinical trials of GM-CSF have been conducted in patients with AIDS, aplastic anemia, myelodysplastic syndromes, and sarcoma and following bone marrow transplantation and accidental radiation exposure. GM-CSF significantly increased circulating numbers of several myeloid cells and produced dose-dependent toxicity consisting primarily of myalgias, fever, fluid retention, and serosal effusions. Additional studies are needed to define the role of GM-CSF in treatment of patients with qualitative and quantitative dysfunction of immune cells.
