PAF receptor

The platelet-activating factor (PAF) receptor is a protein found on the surface of certain cells in the body. It acts like a lock that specifically fits a molecule called PAF, which is involved in processes like inflammation, blood vessel dilation, and immune responses. When PAF binds to the receptor, it triggers various biological reactions, such as making blood vessels more leaky or activating other immune cells. The PAF receptor helps regulate important functions related to allergic reactions, blood clotting, and inflammation, playing a key role in the body's response to injury and infection.
