Vaccination of mice with a Hepatitis B Virus (HBV) core antigen-expressing pCI/C vector did not suppress diabetes induction by a subsequent injection of pCI/ppins (Fig. 1e) and, vice versa, the injection of pCI/ppinsΔA12-21 did not affect the priming of HBV core (Kb/C93-100)-specific CD8+ T cells by a subsequent injection (after 12 days) of the pCI/C vector (Supplementary Fig. S2). The gene discussed is CD8A; the disease is diabetes mellitus.
