IL-6 (Interleukin-6)

Interleukin-6 (IL-6) is a protein produced by your body's immune cells that acts as a signaling molecule to help coordinate immune responses. It plays a key role in promoting inflammation, fighting infections, and aiding in tissue repair. Elevated IL-6 levels are often associated with inflammation-related conditions such as infections, autoimmune diseases, and chronic illnesses. While essential for healthy immune function, too much IL-6 can contribute to harmful inflammation, making it a focus for some treatments targeting inflammatory diseases.
