After a series of intraperitoneal injections of rat monoclonal anti-Lyt 2 antibody supernatant, BDF1 mice showed a loss of cells bearing Lyt 2 surface antigens but no reduction in the numbers of T cells in the spleen. With overnight culture in vitro, splenic T cells from anti-Lyt 2-treated mice regenerated surface Lyt 2, with the proportion of Lyt 2+ cells returning to control levels. Anti-rat IgG antibody was found in the serum of mice that had received the anti-Lyt 2 treatments. Modulation of the surface Lyt 2 antigens was demonstrable in vitro but only in the presence of mouse anti-rat IgG antibody. Functionally, this series of in vivo anti-Lyt 2 antibody treatments substantially reversed Con A-induced suppression of the anti-sheep red blood cell antibody response.
在对BDF1小鼠进行一系列腹腔注射大鼠单克隆抗Lyt 2抗体上清液后,小鼠脾脏中带有Lyt 2表面抗原的细胞数量减少,但T细胞数量未减少。经过体外过夜培养,接受抗Lyt 2处理的小鼠脾脏T细胞表面重新生成Lyt 2,Lyt 2+细胞比例恢复到对照水平。在接受抗Lyt 2处理的小鼠血清中发现了抗大鼠IgG抗体。表面Lyt 2抗原的调节在体外可以证实,但仅在存在小鼠抗大鼠IgG抗体的情况下。在功能上,这一系列体内抗Lyt 2抗体处理显著逆转了伴刀豆球蛋白A诱导的对抗绵羊红细胞抗体反应的抑制作用。
