Abstract

Female murine T cells can respond to the Y antigen of male cells by generating cytotoxic T-killer lymphocytes. Responsiveness is linked to several H-2 genes. Two types of low responders can be distinguished: the B10.A(5R) (H-2i5) strain, a low responder because it lacks Y-specific precursor T cells able to differentiate into cytotoxic T-killer cells; and the CBA/J (H-2k) strain, a low responder because it lacks Y-specific T-helper cells able to support differentiation of T-killer cell precursors. B10.A(5R) stem cells differentiating in an x-irradiated (CBA/J X C57BL/6) (H-2k X H-2b)F1 host respond to Y antigen by generating T-killer cells whereas CBA/J stem cells do not. The results are consistent with the hypothesis that diversity of T-cell receptors is generated by somatic mutation of germ-line genes encoding specificity for self-H-2. A detailed account of this hypothesis is presented.

摘要

雌性小鼠T细胞可通过产生细胞毒性T杀伤淋巴细胞来响应雄性细胞的Y抗原。反应性与多个H-2基因相关。可区分出两种低反应者类型:B10.A(5R)(H-2i5)品系,是低反应者,因为它缺乏能够分化为细胞毒性T杀伤细胞的Y特异性前体T细胞;以及CBA/J(H-2k)品系,是低反应者,因为它缺乏能够支持T杀伤细胞前体分化的Y特异性T辅助细胞。在经X射线照射的(CBA/J×C57BL/6)(H-2k×H-2b)F1宿主中分化的B10.A(5R)干细胞通过产生T杀伤细胞来响应Y抗原,而CBA/J干细胞则不会。这些结果与以下假设一致,即T细胞受体的多样性是由编码对自身H-2特异性的种系基因的体细胞突变产生的。本文对这一假设进行了详细阐述。
