It is hypothesized that interleukin 1 induces toxic free radical formation in pancreatic beta-cells leading to beta-cell degeneration and destruction. Therefore, isolated rat pancreatic islets were examined for interleukin 1 and heat shock induced proteins. Afer exposure to human interleukin 1 beta (0.015 to 10 micrograms/1) or heat (40 degrees C) for up to 24 h, islets were labelled with 35S-methionine and solubilized. Islets proteins were analysed by SDS-polyacrylamide gel electrophoresis. By autoradiography it was shown that both interleukin 1 and heat exposure induced the formation of a 70 kD protein. Further, interleukin 1 induced the formation of two proteins of 32 and 80 kD, respectively, which was not seen after heat exposure. Possibly, the 70 kD protein is a member of the heat shock protein 76 family, participating in unspecific cellular defence and maybe free radical scavenging. Other candidates are the superoxide radical scavenging enzyme manganous superoxidedismutase, MHC class II molecules, and heme oxygenase.
