title: Prevention of graft-versus-host disease by treatment of bone marrow with gliotoxin in fully allogeneic chimeras and their cytotoxic T cell repertoire.
abstract: Gliotoxin, a secondary fungal metabolite, at nanomolar concentrations, irreversibly inhibits murine T cell proliferation to mitogen. Treatment of allogeneic spleen cells with gliotoxin allows their transfer into sublethally irradiated recipients without inducing a GVH reaction. Gliotoxin treatment of bone marrow allows the establishment of fully allogenic bone marrow chimeras free of GVH disease. The cytotoxic T cell repertoire against influenza virus in these animals is restricted to both host- and donor-type MHC. However, their immune competence is severely compromised by their lack of host MHC-type stimulator cells.
