Mice were primed with dinitrophenyl (DNP) (trinitrophenyl, TNP) coupled to thymus-independent (TI) or thymus-dependent (TD) carriers. B cells from these mice were transferred to irradiated recipients with T cells from keyhole limpet hemocyanin (KLH)-primed mice. After secondary immunization with DNP-KLH a significant DNP-specific IgG memory response was produced only by mice which received B cells which had been primed with TD antigens. TI antigens were unable to induce differentiation of B-cell precursors to IgG producing memory B cells but they did not suppress the induction of B-memory cells by TD antigens. The results indicate that TI antigens fail to activate a cell type which is required for the induction of memory B cells.
用与非胸腺依赖性(TI)或胸腺依赖性(TD)载体偶联的二硝基苯基(DNP)(三硝基苯基,TNP)对小鼠进行致敏。将这些小鼠的B细胞与来自钥孔戚血蓝蛋白(KLH)致敏小鼠的T细胞一起转移到经辐照的受体中。在用DNP-KLH进行二次免疫后,仅接受过TD抗原致敏的B细胞的小鼠产生了显著的DNP特异性IgG记忆反应。TI抗原无法诱导B细胞前体分化为产生IgG的记忆B细胞,但它们并未抑制TD抗原诱导B记忆细胞的产生。结果表明,TI抗原未能激活诱导记忆B细胞所需的细胞类型。
