Interleukin-6 (IL-6)

Interleukin-6 (IL-6) is a protein in the body that plays a crucial role in the immune system. It is produced by various cells, especially during infections or injuries, and helps regulate inflammation and immune responses. IL-6 signals other cells to react, promoting healing by triggering the production of more immune cells and substances. However, when produced in excess, it can contribute to chronic inflammation and conditions like autoimmune diseases and certain cancers. Understanding IL-6 is important for developing treatments for these conditions and managing the body’s response to illness.
