<prompt> Answer this question truthfullyWhat is the name of the interleukin that is primarily responsible for inducing fever and acute inflammation?  <response>: <reason> The interleukin that is primarily responsible for inducing fever and acute inflammation is called IL-1. This cytokine is produced by various immune cells, including macrophages and monocytes, in response to infection, injury, or other stimuli. IL-1 acts on the hypothalamus in the brain to induce fever, which is a common symptom of infection and inflammation. In addition to its role in fever, IL-1 also promotes the activation of immune cells, the production of other cytokines, and the recruitment of leukocytes to the site of infection or injury. Dysregulation of IL-1 production or signaling can lead to chronic inflammation and autoimmune diseases, such as rheumatoid arthritis and inflammatory bowel disease.
