B Cell Homing refers to the process by which B cells, a type of white blood cell, migrate to specific tissues in the body. This movement is crucial for the immune response, as it allows B cells to locate areas where they can encounter antigens and produce antibodies. The homing process is guided by various signals, including chemokines and adhesion molecules. These signals help B cells recognize and bind to the blood vessel walls in target tissues, such as lymph nodes or sites of infection, ensuring that they can effectively participate in the immune defense.
