  • Title: The induction and abolition of specific immunosuppression of heart allografts in rats by use of donor blood and cyclophosphamide.
    Author: Marquet R, Heystek G.
    Journal: J Immunol; 1975 Aug; 115(2):405-8. PubMed ID: 239060.
    Abstract:
    Intravenous pretreatment of WAG/Rij rats with BN blood 14 days before transplantation leads to permanent survival of BN heart allografts. Pretreatment with donor blood in the reverse donor-host combination gives rise to accelerated rejection of WAG/Rij hearts. Addition of 100 mg/kg Cy to the pretreatment with donor blood in the WAG/Rij to BN model resulted in permanent graft acceptance, presumably due to the phenomenon of immunologic enhancement. This effect could be observed only if the interval between drug administration and antigen pretreatment was short. The use of Cy had a more profound and long-lasting effect on humoral than on cellular immunity. Addition of 100 mg/kg Cy to the active enhancement protocol in the "easy" BN to WAG/Rij combination produced permanent graft survival in an immunologic setting reminiscent of immunologic tolerance. The combined pretreatment with donor blood and 50 mg/kg Cy in this donor-host combination abolished the operation of immunologic enhancement, which could be induced if donor blood was given alone.
