Interleukin-8 (IL-8)

Interleukin-8 (IL-8) is a protein produced by the body's immune cells that acts as a signaling molecule to coordinate the body's response to infections or injuries. Its main role is to attract immune cells like neutrophils to the site of infection or damage, helping to fight off germs and promote healing. IL-8 is crucial in inflammation, but excessive levels can contribute to chronic inflammatory conditions. Overall, it is an important part of the immune system's communication network, enabling the body to respond effectively to threats.
