CXCR5

CXCR5 is a type of receptor protein found on certain immune cells, like B cells and some T cells. It acts like a GPS marker, helping these cells find their way to specific areas in the lymph nodes and other lymphoid tissues where they can interact and coordinate immune responses. By guiding immune cells to these sites, CXCR5 plays a crucial role in organizing effective immune defenses against infections and in maintaining immune system balance.
