CSF1

CSF1, or colony-stimulating factor 1, is a protein that plays a key role in the health of the immune system. It stimulates the production and survival of a type of immune cell called macrophages, which are essential for fighting infections, cleaning up cellular debris, and supporting tissue repair. CSF1 acts as a signaling molecule, telling stem cells in the bone marrow to produce more macrophages. It is also involved in regulating inflammation and interacts with other cells to maintain immune balance. CSF1's activity is important for normal immune function and tissue health.
