Figure 6. Donor-specific CTL activity of graft-infiltrating cells.
One week after transplantation with Balb/C islets, graft-infiltrating cell were isolated from B6 recipient mice that were immunized with donor MHC DNA vaccines and/or treated with IL-2 regimen prior to transplantation, and analyzed for donor-specific CTL activity. MHC I+IL-2/anti-IL-2, but not MHC II+IL-2, treatments significantly suppressed CTL activity while the treatments with both plus rapamycin further reduced donor-specific CTL activity.
