Inflammatory mediators are substances released by the body during an inflammatory response. They include proteins, lipids, and other molecules that help regulate the immune system's activity. Common inflammatory mediators include cytokines, histamines, and prostaglandins, which work together to promote inflammation, recruit immune cells, and facilitate healing. These mediators can have both beneficial and harmful effects. While they help protect the body from infections and injuries, excessive or prolonged release can lead to chronic inflammation and contribute to diseases such as arthritis and asthma. Understanding these mediators is crucial for developing treatments for inflammatory conditions.
