Abstract

The cell-mediated lympholytic capability of mouse spleen cells stimulated in mixed lymphocyte culture is related to the major histocompatibility complex genotype on target lymphocytes. The strain combinations AQR-B10. T(6R) and B10.A(4R)-B10.A(2R) that result in significant mixed lymphocyte culture activation do not mediate cell-mediated lympholysis on sensitizing target lymphocytes; serologically defined regions (H-2K and H-2D) are identical within each combination. H-2K or H-2D region disparity alone does not cause cell-mediated lympholysis. However after mixed lymphocyte culture activation as seen with B10.A-B10.T(6R), a target cell bearing only an H-2K region difference from the effector cell is sensitive to cell-mediated lympholysis. Likewise an H-2D region difference is an adequate target after mixed lymphocyte culture activation of the effector cell in the combination B10.A(2R)-B10.D2.

摘要

在混合淋巴细胞培养中受到刺激的小鼠脾细胞的细胞介导溶淋巴细胞能力与靶淋巴细胞上的主要组织相容性复合体基因型有关。导致显著混合淋巴细胞培养激活的品系组合AQR - B10.T(6R)和B10.A(4R) - B10.A(2R)不会介导对致敏靶淋巴细胞的细胞介导溶淋巴细胞作用;在每个组合中,血清学定义的区域(H - 2K和H - 2D)是相同的。单独的H - 2K或H - 2D区域差异不会引起细胞介导溶淋巴细胞作用。然而,如在B10.A - B10.T(6R)中所见,在混合淋巴细胞培养激活后,仅与效应细胞存在H - 2K区域差异的靶细胞对细胞介导溶淋巴细胞作用敏感。同样,在组合B10.A(2R) - B10.D2中效应细胞经混合淋巴细胞培养激活后,H - 2D区域差异足以成为靶标。
