IL-6

Interleukin-6 (IL-6) is a protein, or cytokine, that plays a key role in the immune system’s response to infections and injuries. It helps coordinate inflammation and stimulates immune cells to fight pathogens. IL-6 levels increase during infections, injuries, or inflammation, signaling the body to react appropriately. While essential for defense and healing, excessive IL-6 can contribute to chronic inflammation and related health issues. It is also involved in processes like fever and regulating immune responses, making it a critical mediator for maintaining bodily balance during immune challenges.
