Graft-versus-host reactions: clues to the etiopathology of a spectrum of immunological diseases.

Parental strain T lymphocytes injected into adult F, mice respond to allogeneic MHC antigens and so induce the symptoms of systemic graft v. host disease (GVHD). GVHD has two forms, stimulatory and suppressive, and in each there are pathological changes which resemble those seen in a variety of human disorders of immune regulation. In this article Ernst Gleichmann and his colleagues review the pathogenesis of these disorders and their induction by GVH reactions.
