GM-CSF (CAS 83869-56-1)

GM-CSF (Granulocyte-Macrophage Colony-Stimulating Factor) is a vital cytokine in the regulation of hematopoietic cell function and the immune system. It is primarily involved in the stimulation of the production and differentiation of two major classes of white blood cells—granulocytes and macrophages. GM-CSF is extensively used in scientific research to understand the complex interactions within the immune system and the regulation of cells that are crucial for innate and adaptive immunity. The action mechanism of GM-CSF centers around its ability to bind to specific cell surface receptors (GM-CSF receptors), which activates a cascade of intracellular signaling pathways, including the JAK/STAT, PI3K/AKT, and MAPK pathways. This leads to the proliferation and differentiation of progenitor cells into mature granulocytes and macrophages. Additionally, GM-CSF enhances the survival and function of these immune cells, making it a key factor in immune responses. GM-CSF is commonly used to culture dendritic cells and macrophages from progenitors in bone marrow or peripheral blood, providing a powerful tool to study the development and function of these cells under various conditions. It also aids in the investigation of disease models, particularly those related to inflammation and autoimmunity, where GM-CSF levels are often dysregulated.
