IL-2 receptor

The IL-2 receptor is a protein found on certain immune cells called T cells. It acts like a lock that recognizes and binds to a specific molecule called interleukin-2 (IL-2), which is a signaling protein that helps stimulate immune responses. When IL-2 binds to its receptor, it activates the T cells, encouraging them to grow, multiply, and fight infections or abnormal cells. This receptor is essential for regulating immune activity, ensuring the body can respond effectively to threats without overreacting.
