title: Abrogation of negative selection by GVHR induced by minor histocompatibility antigens or H-2D antigen alone.
abstract: Allogeneic bone marrow chimeras were prepared by donor and recipient combinations that differed in minor histocompatibility loci or H-2D locus alone. When 1 x 10(5) splenic T cells were inoculated in addition to T cell-depleted bone marrow cells (1 x 10(7)), clinically detectable GVHR was induced. In these GVHR chimeras, substantial numbers of T cells reactive to either donor or recipient antigens were both phenotypically and functionally detected. The mechanisms underlying the abrogation of intrathymic negative selection are discussed.
