N2 - Syngeneic graft-vs.-host disease (SGVHD) develops in rodents following the treatment of lethally irradiated, bone marrow (BM) reconstituted animals with a short course of the immunosuppressive agent cyclosporine A (CsA). Using an in vivo depletion approach, we recently demonstrated that CD4+, but not CD8+, T cells participated in inducing SGVHD. Studies were therefore undertaken to adoptively transfer SGVHD into lethally irradiated, syngeneic BM reconstituted secondary recipients. Whole T cell populations as well as purified CD4+T cells isolated from SGVHD, but not normal or transplant control, animals mediated the transfer of SGVHD into secondary recipients. These cells have an apparent specificity for enteric bacterial antigens. The pathologic process that developed was identical to that observed in the animals with de novo SGVHD after syngeneic BMT and CsA therapy. It was shown that a radiation-sensitive mechanism prevented the transfer of SGVHD into normal, nonirradiated secondary recipients. The ability to reproducibly transfer SGVHD into secondary recipients will enhance our ability to study regulatory mechanisms that are altered during CsA therapy and permit the development of murine CsA-induced SGVHD.
