title: In vitro reactivity in allograft tolerance: persistence of mixed leukocyte culture reactivity in highly tolerant rats.
abstract: Mixed leukocyte culture reactivity was studied in adult W/Fu rats judged to be highly tolerant after the inoculation of (W/Fu X BN)F1 hybrid spleen and bone marrow cells at birth. Reactivity was observed in a majority of tolerant donors tested and documented by quantitative dose-response and kinetic studies. Allograft tolerance cannot be explained by a complete lack of specific immune reactivity to tolerated alloantigens.
