Cytokines and Inflammation

Cytokines are small proteins that cells of the immune system use to communicate and coordinate responses to infection or injury. When the body detects a problem, cytokines are released to trigger inflammation—a natural process where blood flow increases, immune cells arrive, and tissues repair themselves. This inflammation helps fight off germs and heal damage, but if it becomes excessive or chronic, it can lead to tissue damage and health issues. Essentially, cytokines help regulate inflammation, which is a vital part of the body's defense system.
