The ability of cytotoxic T lymphocytes (CTL) induced in vitro to trinitrophenyl (TNP)-modified syngeneic cells to cross-reactively lyse a TNP allogeneic spleen target varies among inbred mouse strains. The cross-reactive CTL phenotype was found to be histocompatibility 2 (H-2) linked and to be dominant in F1 hybrid mice. All strains investigated demonstrated cross-reactivity except for some strains bearing portions of the H-2k haplotype. The gene(s) controlling this response maps to the K and/or I-A region of the H-2 complex. We have termed the immune response (Ir) gene responsible for controlling the specificity of CTL induced to TNP-modified syngeneic cells Ir-X-TNP.
体外诱导产生的细胞毒性T淋巴细胞(CTL)对三硝基苯基(TNP)修饰的同基因细胞进行交叉反应性裂解同种异体脾靶细胞的能力,在近交系小鼠品系中有所不同。发现交叉反应性CTL表型与组织相容性2(H-2)相关,并且在F1杂种小鼠中占主导地位。除了一些携带H-2k单倍型部分的品系外,所有研究的品系都表现出交叉反应性。控制这种反应的基因定位于H-2复合体的K和/或I-A区域。我们将负责控制对TNP修饰的同基因细胞诱导产生的CTL特异性的免疫反应(Ir)基因称为Ir-X-TNP。
