1.MECHANISM OF ACTION

GM-CSF binds to its specific heterodimeric receptor (GM-CSFR) expressed on target cells, initiating JAK/STAT signaling pathways. This binding activates downstream signaling cascades including STAT5 phosphorylation, leading to transcriptional regulation of genes involved in cell survival, proliferation, and differentiation. The cytokine promotes the expansion and maturation of myeloid progenitor cells into granulocytes, macrophages, and dendritic cells. Additionally, GM-CSF enhances the functional activity of mature immune cells, including phagocytosis, antigen presentation, and cytokine production. The signaling cascade also involves MAPK and PI3K pathways, contributing to the pleiotropic effects on immune cell activation and survival.
