Platelet Activating Factor

Platelet Activating Factor (PAF) is a chemical compound in the body that plays a key role in inflammation and immune responses. It is primarily involved in activating cells like platelets (which help with blood clotting), promoting blood vessel dilation, and attracting immune cells to sites of injury or infection. PAF helps coordinate the body's defense mechanisms but can also contribute to inflammatory conditions if produced excessively. It acts by binding to specific receptors on cell surfaces, triggering various biological effects that are crucial for healing and defense but may also be involved in allergic and inflammatory diseases.
