- Abstract
Increasing data suggest a possible viral aetiology of juvenile onset, insulin-dependent diabetes mellitus. The M variant of the encephalomyocarditis (EMC) virus infects murine pancreatic beta cells and causes a diabetes like syndrome in susceptible strains of mice. Abnormalities in immunological function have been documented in patients with diabetes mellitus and in spontaneous. streptozotocin-induced and alloxan-induced diabetes in animals. The present study documents a significant impairment of the ability of mice with EMC virus (M variant)-induced diabetes to generate a direct. IgM PFC response after in vivo immunization with sheep erythrocytes. This abnormality appears to be a direct consequence of the diabetic state and not EMC virus infection, per se, since (1) mice infected with EMC virus that do not become diabetic have normal direct PEC responses and (2) islet cell transplantation, which cures the diabetes. corrects the defect in PFC responsiveness.
