Abstract

Selected L3T4- and Lyt 2- T-cell subpopulations from Listeria monocytogenes-infected mice were transferred into syngenic recipients, and their capacity to adoptively mediate protection against L. monocytogenes and delayed-type hypersensitivity to listerial antigens was determined. Both functions were markedly reduced by pretreatment of cells with either anti-L3T4 or anti-Lyt 2.2 antibodies plus complement, but they could be restored by admixture of the two selected T-cell subsets. Thus, after systemic cell transfer effective protection against L. monocytogenes and delayed-type hypersensitivity to listerial antigens depend on cooperation between specific L3T4+ and Lyt 2+ T cells.

摘要

从感染单核细胞增生李斯特菌的小鼠中选取L3T4和Lyt 2 T细胞亚群,将其转移至同基因受体小鼠体内,并测定它们过继介导抗单核细胞增生李斯特菌保护作用及对李斯特菌抗原迟发型超敏反应的能力。用抗L3T4或抗Lyt 2.2抗体加补体预处理细胞后,这两种功能均显著降低,但将两个选定的T细胞亚群混合可使其恢复。因此,全身细胞转移后,对单核细胞增生李斯特菌的有效保护作用及对李斯特菌抗原的迟发型超敏反应取决于特定的L3T4⁺和Lyt 2⁺ T细胞之间的协作。
