Graft-versus-host reaction: a pathogenetic principle for the development of drug allergy, autoimmunity, and malignant lymphoma in non-chimeric individuals. Hypothesis.
It is proposed that the same diseases as those induced by the graft-versus-host reaction (GVHR) will arise in nonchimeric individuals, if structures of the major histocompatibility complex (MHC) on lymphocytes are altered, either by viral infection or by chemicals, in such a way that autologous T lymphocytes react against them as the react in the GVHR to semiallogeneic (F1) lymphocytes differing at the MHC. Diseases in which a GVHR-like pathogenesis is suspected will be discussed.
