IL-12

IL-12 (Interleukin-12) is a protein produced by immune cells that helps activate other immune cells, particularly those involved in fighting infections and cancer. It acts as a messenger, signaling immune cells to coordinate responses against pathogens. IL-12 boosts the activity of T cells and natural killer cells, enhancing the body's ability to identify and destroy harmful microbes and abnormal cells. Overall, it plays a key role in regulating and directing the immune response, making it an important component in the body's defense system.
