Spleen cells from mice systemically infected 4 to 6 weeks previously with Mycobacterium lepraemurium gave an enhanced primary antibody response in vitro to sheep erythrocytes, but responded normally to dinitrophenylated polyumerized flagellin. The ability to enhance the response was associated with the glass-adherent spleen cell population and with peritoneal cells. Similar cells obtained from infected mice depleted of T lymphocytes failed to enhance the antibody response. These studies suggest that macrophages that became activated during the development of cell-mediated immunity to infection can also stimulate antibody responses to thymus-dependent antigens.
4至6周前全身感染鼠麻风杆菌的小鼠脾脏细胞,在体外对绵羊红细胞产生增强的初次抗体反应,但对二硝基苯基化聚合鞭毛蛋白反应正常。增强反应的能力与玻璃黏附性脾脏细胞群体及腹腔细胞有关。从感染小鼠中获得的、T淋巴细胞已耗尽的类似细胞无法增强抗体反应。这些研究表明,在针对感染的细胞介导免疫发展过程中被激活的巨噬细胞,也能刺激对胸腺依赖性抗原的抗体反应。
