Abstract

Athymic mice were capable of producing IgM antibodies to B polysaccharide of N. meningitidis when immunized with the polysaccharide complexed to outer membrane proteins, whereas no immunogenicity could be demonstrated with the purified polysaccharide. Transfer of T cells to athymic cells demonstrated that the primary anti-B response was truly thymus-independent but the bulk of the secondary response was thymus-dependent. Transfer of T and B cells purified from spleens of immune mice into irradiated recipients showed the presence of memory T cells, but no memory B cells could be found.

摘要

无胸腺小鼠在用与外膜蛋白复合的多糖免疫时,能够产生针对脑膜炎奈瑟菌B多糖的IgM抗体,而纯化的多糖则无免疫原性。将T细胞转移至无胸腺细胞表明,初次抗B反应确实是胸腺非依赖性的,但大部分二次反应是胸腺依赖性的。将从免疫小鼠脾脏中纯化的T细胞和B细胞转移至受辐照的受体,结果显示存在记忆T细胞,但未发现记忆B细胞。
