We developed two distinct transgenic mouse models in which virus induced insulin-dependent (type 1) diabetes mellitus (IDDM). In one of these lines, the unique viral transgene was expressed in the islets of Langerhans and also in the thymus, but in the other line, expression was only in the islets. Insertion and expression of the viral (self) gene, per se, did not lead to IDDM, (incidence < 5%). By contrast, induction of an anti-self (anti-viral) CD8+ CTL response to the same virus later in life caused IDDM (incidence < 90%) in both transgenic lines, although the kinetics and requirements for CD4 help, the affinity and avidity of CD8+ CTL differed in each line. Mice not expressing the viral (self) gene in the thymus developed IDDM 10-14 days after infection. CD4+ T cells played no detectable role, since their depletion failed to alter either the kinetics or incidence of IDDM. By contrast, mice that expressed the viral gene in the thymus required significantly more time to develop IDDM. Their anti-self (viral) CD8+ CTL were of lower affinity and avidity than CD8+ CTL generated by nontransgenic controls. Disease was dependent on T cell help, since deletion of CD4+ cells completely circumvented the IDDM.
