Inflammatory signals are molecules produced by the body in response to injury or infection. These signals, such as cytokines and chemokines, help recruit immune cells to the affected area, promoting healing and fighting off pathogens. They play a crucial role in the body's defense mechanisms. However, excessive or prolonged inflammatory signals can lead to chronic inflammation, which is linked to various diseases, including arthritis, diabetes, and heart disease. Understanding these signals is essential for developing treatments that can modulate inflammation and improve health outcomes.
