Bone marrow cells from C3H (H-2k) mice, a strain that does not exhibit cross-reactive lysis of trinitrophenyl (TNP)-modified allogeneic targets, were allowed to mature in heavily irradiated (B6 times C3H)F1 (H-2b/k) recipients, an F1 hybrid that does demonstrate cross-reactive lysis. Spleen cells from these chimeric mice were removed after 3-4 mo and by H-2 typing shown to be of C3H origin. These cells were found to be tolerant to B6 alloantigens by mixed lymphocyte reaction and cell-mediated cytotoxicity and, when stimulated in vitro with TNP-modified syngeneic cells, now cross-reactively lysed TNP-modified allogeneic targets. These studies demonstrate that the host environment where T cells differentiate influences the specificity of the primary cytolytic T-lymphocyte (CTL) response to TNP-modified syngeneic antigens.
来自C3H(H-2k)小鼠的骨髓细胞,该品系不会对三硝基苯基(TNP)修饰的同种异体靶标表现出交叉反应性裂解,将其置于经重度照射的(B6×C3H)F1(H-2b/k)受体小鼠体内使其成熟,(B6×C3H)F1是一种确实会表现出交叉反应性裂解的F1杂种小鼠。3至4个月后,从这些嵌合小鼠体内取出脾细胞,通过H-2分型显示其来源于C3H。通过混合淋巴细胞反应和细胞介导的细胞毒性发现,这些细胞对B6同种异体抗原具有耐受性,并且当在体外被TNP修饰的同基因细胞刺激时,现在能够交叉反应性地裂解TNP修饰的同种异体靶标。这些研究表明,T细胞分化所处的宿主环境会影响初始细胞毒性T淋巴细胞(CTL)对TNP修饰的同基因抗原的反应特异性。
