Cytokine Receptor

A cytokine receptor is a specialized protein found on the surface of certain cells. It functions like an antenna, detecting signaling molecules called cytokines, which are released by immune cells. When a cytokine binds to its receptor, it triggers a series of internal signals that tell the cell how to respond—such as dividing, moving to a new location, or producing other immune molecules. These receptors are essential for coordinating the body's immune response, helping to fight infections, control inflammation, and maintain overall immune system balance.
