M-CSF receptor

The M-CSF receptor is a protein found on the surface of certain immune cells called monocytes and macrophages. It acts like a lock that activates when it binds to a specific molecule called M-CSF (macrophage colony-stimulating factor). This activation signals the cell to grow, survive, and develop into mature macrophages, which are important for fighting infections and removing cell debris. The receptor plays a critical role in immune system regulation and bone health, and its malfunction can be linked to diseases like certain cancers and disorders involving bone destruction.
