inflammation mediators

Inflammation mediators are substances released by the body's immune system in response to injury or infection. They help coordinate the body's defense by causing blood vessels to expand, increasing blood flow, and signaling other immune cells to the site of damage. This process results in common signs like redness, swelling, heat, and pain. Key mediators include chemicals like histamine, prostaglandins, and cytokines, which work together to protect tissues, promote healing, and fight off harmful germs. However, excessive or chronic production of these mediators can contribute to ongoing inflammation and tissue damage.
