Chemokine receptors are specialized proteins found on the surface of certain cells, particularly in the immune system. They play a crucial role in guiding the movement of immune cells to sites of infection or inflammation by responding to signaling molecules called chemokines. This process is essential for the body’s defense against pathogens and for tissue repair. These receptors are part of a larger family known as G protein-coupled receptors, which transmit signals from outside the cell to the inside. When a chemokine binds to its corresponding receptor, it triggers a series of cellular responses, enabling immune cells to migrate effectively and perform their functions.
