Abstract

Adult, male ICR Swiss mice are susceptible to the diabetogenic effects of the D-variant of encephalomyocarditis virus (EMC-D) in contrast to adult C3H/HeJ male mice, which are relatively resistant. To date, experimental evidence suggests that the immune system plays a role in the pathogenesis of this infection. We have investigated the potential involvement of the immune system in the pathogenesis of EMC-D-induced diabetes using cyclosporin-A (CyA), a potent immunosuppressive drug. The data show that treatment with CyA results in increased severity and incidence of diabetes in susceptible ICR Swiss mice and induction of diabetes in resistant C3H/HeJ mice. It is concluded that immune mediation probably is not involved in the early pathogenesis of EMC-D-induced diabetes in mice.
