We have attempted to verify that acquired characteristics can be transmitted through the male germ line by using as a model system the vertical transmission of specific immunological tolerance to major histocompatibility antigens. Tolerant males were a tetraparental mouse and separated parabionts, in each case showing stable lymphoid chimerism. Tolerance in the progeny was assessed by two in vivo assays, rejection of cardiac allografts and clearance of 131I-labeled tumor cells. We were unable to find evidence for heritability of the tolerant state in tetraparental or parabiont males, with either assay system.
我们试图通过将对主要组织相容性抗原的特异性免疫耐受性的垂直传递作为模型系统,来验证获得性特征是否可通过雄性生殖系进行传递。耐受性雄性包括四亲本小鼠和联体共生小鼠,在每种情况下均表现出稳定的淋巴嵌合现象。通过两种体内试验评估后代的耐受性,即心脏同种异体移植排斥反应和131I标记肿瘤细胞的清除情况。在四亲本或联体共生雄性中,使用任何一种试验系统,我们都未能找到耐受状态具有遗传性的证据。
