Csf1 Protein is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
CSF1 (Colony Stimulating Factor 1), also known as M-CSF (Macrophage Colony-Stimulating Factor), is a hematopoietic growth factor that binds CSF1R to regulate monocyte/macrophage lineage cells, including microglia in the central nervous system. [@csfmediated]
Overview
CSF1 Protein (Colony Stimulating Factor 1), also known as M-CSF (Macrophage Colony-Stimulating Factor), is a homodimeric cytokine that binds to the colony-stimulating factor 1 receptor (CSF1R). It is essential for the survival, proliferation, and differentiation of microglia and macrophages. CSF1 protein is a key therapeutic target for modulating neuroinflammation in Alzheimer's disease, Parkinson's disease, and other neurodegenerative disorders. [@csfr]
