Abstract

The validity of the use of the NZB mouse as a model for systemic lupus erythematosus is supported by a study of the 7S and 19S antibody response to immunization with sheep erythrocytes. In comparison with CBA and C3H mice the 2-month-old NZB animals made significantly more whole serum antibody. DBA, C57BL and A/Jax animals made about the same amount of whole serum antibody. Compared to all the control groups the NZB animals made significantly more 7S antibody in eight of twenty examinations of 2-mercaptoethanol resistant antibody studied from 1 to 8 weeks after immunization. Old NZB animals showed the same degree of 7S antibody production as the 2-month-old animals and were no different from a group of old White Swiss mice. The NZB animals thus show early immunological hyperreactivity most prominently in the 7S immunoglobulin fraction at a time when virtually no autoantibodies are present.

摘要

一项关于用绵羊红细胞免疫后7S和19S抗体反应的研究支持了将NZB小鼠用作系统性红斑狼疮模型的有效性。与CBA和C3H小鼠相比,2月龄的NZB动物产生的全血清抗体明显更多。DBA、C57BL和A/Jax动物产生的全血清抗体量大致相同。在免疫后1至8周对2-巯基乙醇抗性抗体进行的20次检测中,有8次显示,与所有对照组相比,NZB动物产生的7S抗体明显更多。老年NZB动物产生7S抗体的程度与2月龄动物相同,与一组老年瑞士白化小鼠没有差异。因此,NZB动物在几乎不存在自身抗体的时候,就已在7S免疫球蛋白部分最显著地表现出早期免疫反应亢进。
