IL1B (Interleukin 1 Beta): IL1B is a key cytokine involved in the inflammatory response and various immune functions. It activates and recruits immune cells to sites of infection or injury and helps induce fever. Dysregulation of IL1B is associated with chronic inflammatory and autoimmune diseases such as rheumatoid arthritis, gout, and sepsis. As a potent mediator of inflammation, IL1B is a target for multiple anti-inflammatory therapies.
