We characterized autoreactive T-cell clones derived from (NZB x NZW)F1 (B/WF1) mice. These autoreactive T-cell clones are shown to be CD4+ by immunofluorescence staining and to belong to Th2 type by cytokine release assay. Specificity analysis revealed the existence of mixed haplotype A beta z/A alpha d major histocompatibility complex (MHC) class II molecule-specific T-cell clones as well as A beta z/A alpha z- or A beta d/A alpha d-specific T-cell clones. Some but not all of the mixed haplotype A beta z/A alpha d-specific autoreactive T-cell clones showed strong activity to induce IgG anti-DNA antibody production upon transfer to young (4-month-old) B/WF1 mice, indicating that T cells with these specificities might be involved in B/WF1 autoimmunity.
我们对源自(新西兰黑鼠×新西兰白鼠)F1(B/WF1)小鼠的自身反应性T细胞克隆进行了表征。通过免疫荧光染色显示,这些自身反应性T细胞克隆为CD4+,通过细胞因子释放试验表明它们属于Th2型。特异性分析揭示了存在混合单倍型Aβz/Aαd主要组织相容性复合体(MHC)II类分子特异性T细胞克隆以及Aβz/Aαz或Aβd/Aαd特异性T细胞克隆。部分(而非全部)混合单倍型Aβz/Aαd特异性自身反应性T细胞克隆在转移至年轻(4个月大)的B/WF1小鼠后,表现出强烈的诱导IgG抗DNA抗体产生的活性,这表明具有这些特异性的T细胞可能参与了B/WF1小鼠的自身免疫反应。
