Costimulation via the B7/CD28 pathway is an important signal for the activation of T cells. Maximal inhibition of T-cell activation and the induction of alloantigen-specific nonresponsiveness in vitro was achieved using anti-CD80 monoclonal antibody (mAb) in combination with cyclosporin A (CsA). Based on this knowledge, the efficacy of the prophylactic treatment of anti-CD80 mAb and CsA on allogeneic skin graft survival was tested in a preclinical rhesus monkey model. No side effects have been observed. Administration of anti-CD80 mAb resulted in high mAb serum levels that decreased to undetectable values around day 7. At the same time, the anti-mouse antibody response started to develop. The anti-CD80 mAb bound to peripheral blood mononuclear cells and was detectable in lymph node and grafted skin during the treatment period. The skin graft survival time of untreated or suboptimally CsA-treated rhesus monkeys was 10 days. Treatment with CsA (blood levels of 100-160 ng/ml) in combination with anti-CD80 mAb (0.5 mg/kg) resulted in a significantly increased skin graft survival time to 14 days. Eventually, skin grafts in all rhesus monkeys were rejected, which coincided with an increase in helper and cytotoxic T-cell frequency and induction of an antibody response directed against the donor antigens. Therefore, treatment of anti-CD80 mAb in combination with CsA has significant immunosuppressive potency, but was unable to induce donor-specific nonresponsiveness in skin graft recipients.
