title: Dissociation of the proliferative and effector non-H-2 minor histocompatibility-alloimmune responses.
abstract: The first-set and second-set allotransplantation reactions against skin grafts and the primary and secondary proliferative graft-versus-host reactions in the popliteal lymph nodes were compared in both directions in a non-H-2 system (mouse strain combinations C57BL/10ScSnPh (further B10) and B10.C3H(40NX) further 40NX) differing at H-1 plus H-?). While 40NX recipients gave stronger reactions against B10 antigens in the allotransplantation reactions, the situation was reversed in the GVHR, B10 cells reacting more strongly against 40NX antigens. The findings of a dissociation between the mechanisms of allotransplantation reaction adn proliferative GVHR suggest that the genetic determination of the target antigens and the reacting lymphocyte populations are more complex at the minor histocompatibility systems than has been expected.
