CXCR4

CXCR4 is a protein found on the surface of certain cells, acting like a receptor that detects signals from the environment. It plays a crucial role in guiding cells, especially immune cells, to areas needing repair or defense, and in processes like blood cell production. CXCR4 also interacts with a chemical called CXCL12, which helps direct cell movement. Additionally, some cancer cells exploit CXCR4 to spread and invade other parts of the body. Understanding CXCR4 is important for developing treatments for cancers, infections, and regenerative medicine.
