携带隐性Ipr基因的小鼠会发生年龄依赖性的大量淋巴细胞增生,主要发生在淋巴结(LN),并伴有相关的自身免疫。这些小鼠的LN细胞在细胞表面表达的T细胞受体蛋白为正常水平的50-70%。与正常LN细胞相比,在这些细胞中发现了正常水平的T细胞受体α、β和γ mRNA。MRL‐lpr/lpr LN DNA的Southern blot分析显示,80-90%的染色体在β基因位点重排。重排模式表明T细胞发生了多克隆扩增而非单克隆扩增。这些数据支持MRL - lpr小鼠淋巴细胞增殖的淋巴因子诱导模型。
Mice bearing the recessive gene Ipr develop an age‐dependent, massive lymphoproliferation, primarily in the lymph nodes (LN), with associated autoimmunity. LN cells from these mice express T cell receptor protein on the cell surface at 50–70% of normal levels. Normal levels of T cell receptor α, β and γ mRNA were found in these cells as compared to normal LN cells. Southern blot analysis of MRL‐lpr/lpr LN DNA showed rearrangements in 80–90% of the chromosomes at the β gene loci. The pattern of rearrangement indicated that a polyclonal rather than monoclonal expansion of T cells occurred. These data support a lymphokine‐induction model of lymphoproliferation in MRL‐lpr mice.
