一类特殊的自身抗原(内源性超抗原)能够根据小鼠T细胞受体Vβ基因片段的表达来清除许多小鼠T细胞。在内源性表达这些抗原的小鼠中,耐受部分是通过相关的V-β携带T细胞1-17的克隆缺失来调节的。I-E-反应性V-β5.2携带T细胞的缺失依赖于I-E耐受结合(ETC)14的共表达,并且这些结合之一的基因ETC-1映射到12号染色体上,靠近小鼠乳腺肿瘤病毒整合基因MTV-9。在这里,我们报道了ETC-1和MTV-9之间的完美遗传连锁,并表明ETC-1还参与了含有Vβ5.1和Vβ11结构域的T细胞的I-E依赖缺失。我们还证明了MTV-9转录本存在于表达ETC-1的B细胞中,并表明大约15%的T淋巴细胞识别的粘连是由MTV-9基因组编码的。
A SPECIAL class of self-antigens (endogenous superantigens) is capable of deleting many murine T cells on the basis of their expression of particular T-cell receptor Vβ gene segments. In mice that endogenously express these antigens, tolerance is mediated in part by the clonal deletion of the relevant Vβ-bearing T cells1–17. The deletion of I–E-reactive Vβ 5.2-bearing T cells is dependent on the coexpression of an I–E tolerogenic coligand (Etc)14 and the gene for one of these coligands, Etc-1, maps to chromosome 12, near the mouse mammary tumour viral integrant, Mtv-9. Here we report a perfect genetic linkage between Etc-1 and Mtv-9 and show that Etc-1 is also involved in the I–E-dependent deletion of T cells bearing Vβ5.1 and Vβ11 domains. We also demonstrate that Mtv-9 transcripts are present in B cells expressing Etc-1 and suggest that the coligand recognized by roughly 15% of all T lymphocytes is encoded by the Mtv-9 genome.
