Abstract

Experimental evidence presented in this paper suggests that the T cell hyperreactivity of NZB mice against H-2 identical target cells is a true primary response and not the consequence of an in vivo T cell autoimmune priming event. Based on additional data, we believe an elevated potential of T cell help to be present in NZB mice, which facilitates the observed hyperreactivity F1 hybrids of NZB and normal strains of mice inherited the capacity to hyperreact against H-2 identical cells in an H-2-unrestricted fashion. Because the hybrids tested possess both Qa-1 alleles--Qa-1b and Qa-1a--our experiments either indicate the existence of heterogeneity within the Qa-1b system or of an H-2-unrestricted response against additional target antigens. The T cell hyperreactivity might prove to be a valuable tool in further investigations of the pathomechanism of autoimmune disease.

摘要

本文中呈现的实验证据表明,NZB小鼠针对H-2相同靶细胞的T细胞高反应性是一种真正的初级反应,而非体内T细胞自身免疫致敏事件的结果。基于其他数据,我们认为NZB小鼠体内存在增强的T细胞辅助潜能,这促成了所观察到的高反应性。NZB与正常小鼠品系的F1杂种继承了以H-2非限制性方式针对H-2相同细胞产生高反应的能力。由于所测试的杂种同时拥有两个Qa-1等位基因——Qa-1b和Qa-1a——我们的实验要么表明Qa-1b系统内存在异质性,要么表明存在针对其他靶抗原的H-2非限制性反应。T细胞高反应性可能会被证明是进一步研究自身免疫疾病发病机制的一个有价值的工具。
