Abstract
Adult male ICR Swiss mice develop insulin-dependent diabetes when infected with the D variant of encephalomyocarditis virus (EMC-D). In contrast, adult C57Bℓ/6 males are relatively resistant to the diabetogenic effects of this virus. We have been studying the role of interferon (IFN) in the pathogenesis of infection by EMC-D and development of virus-induced murine diabetes mellitus. The data show that when IFNβ or IFNγ were administered four days after virus infection, the frequency and severity of diabetes were exacerbated in ICR Swiss mice, and the diabetic state was induced in the resistant C57Bℓ/6 strain. In addition, animals treated with either of the IFNs or the IFN-inducer poly I:C, developed symptoms of severe encephalomyocarditis. Analysis of ICR Swiss mouse tissues revealed that IFN-treatment resulted in virus replication in the heart and brain and the reappearance of the virus in the pancreas. It is concluded that under certain conditions, the diabetic state is exacerbated and the normal course of (EMC-D)-infection in mice is altered by IFN.
