Spleen cells from LAF(1) mice hyperimmune to sheep erythrocytes (SE) lost their ability to transfer a secondary response to irradiated recipients after incubation with anti-theta and rabbit complement in vitro. Small numbers of specific immune cells even when taken 3 days after a primary SE injection reconstituted the direct and indirect plaque-forming cell responses. Larger numbers of cells sensitized to B. abortus (or keyhole limpet hemocyanin), and given together with the corresponding antigen, also partially reconstituted the ability to respond to SE. This property was mediated by theta-bearing cells and was interpreted as due to a nonspecific humoral factor liberated by specifically activated T cells and acting on B cell proliferation or maturation.
来自对绵羊红细胞(SE)高度免疫的LAF(1)小鼠的脾细胞,在体外与抗θ血清和兔补体孵育后,失去了向受辐照受体传递二次反应的能力。即使在初次注射SE后3天获取的少量特异性免疫细胞,也能重建直接和间接的空斑形成细胞反应。大量对流产布鲁氏菌(或钥孔血蓝蛋白)致敏并与相应抗原一起给予的细胞,也能部分重建对SE的反应能力。这种特性由携带θ的细胞介导,被解释为是由于特异性活化的T细胞释放的一种非特异性体液因子作用于B细胞增殖或成熟所致。
