IL-1 was isolated from human blood that had been exposed to a pathogenic bacterium. IL-1 is a pyrogen, and it is an activating factor for lymphocytes. It also damaged joints and influenced liver proteins (2). IL-1alpha binds to the cell surface type I and II IL-1 receptors (IL-1RI and IL-1RII). IL-1 and -beta and IL-1RA can compete for binding to these receptors. However, only IL-1RI, not IL-1RII, is functional because IL-1RII lacks a cytoplasmic domain and is thus unable to transmit signals to downstream steps (3). IL-1alpha is expressed by cancer cells and promotes angiogenesis and metastasis of pancreatic cancer and human gastric cancer cell lines (4). In addition, IL-1 induced the expression of VEGF in colon cancer (5).
