Interleukin-1α (IL-1α), also known as IL-1F1 or hematopoietin-1, is a glycosylated protein. IL-1α is produced by activated macrophages and along with IL-1β, it stimulates thymocyte proliferation by inducing IL-2 release and is an endogenous pyrogen. There are multiple receptors of IL-1α. Along with IL-1β, IL-1α binds directly to IL-1 RI, which is then associated with IL-1 R accessory protein (IL-1RAcP) to form a high affinity receptor complex for signal transduction. IL-1 RII has high affinity for IL-1α, but it is a negative regulator of IL-1α activity. IL-1 receptor antagonist (IL-1ra) interacts with IL-1 RI, preventing it from binding IL-1α and IL-1β. IL-1α is associated with a number of disorders such as cerebral amyloid angiopathy-related hemorrhage, periodontal disease, and silicosis.
