Abstract:
:By cytolysis and monolayer absorption tests, the kinetics of the generation of CBA/H cytotoxic lymphocytes (Tc) in response to stimulation by H-2b antigens have been analyzed in vitro. The Tc population which reacts with public antigens of H-2b and H-2d strains shows peak activity in culture at 4 to 5 days, then rapidly decreases. The population with cytotoxic activity against the private antigens of H-2b cells peaks later and persists longer. The antipublic cytolytic activity was shown to be specific and not attributable to antibody-dependent cell-mediated cytotoxicity (ADCMC), but was attributable to Ly1-, 2+ effector cells. By suitable conditions of absorption on C57BL/10 monolayers, the precursors of the antiprivate clone could be selectively removed without impairing the antipublic H-2d response. These and previous results present an argument that the cross-reactivity which Tc display on different H-2 haplotypes is attributable to clones directed against shared determinants and is not attributable to low affinity binding of Tc activated by private H-2 antigens.

TRANSPLANTATION文献大全abstract:BACKGROUND:Lower liver transplant success is observed when the donor is female. Intracellular acidosis during ischemia is proposed to contribute to the injury sustained by the transplanted organ and its role in livers obtained from nonheartbeating donors is unclear.
