Abstract

Spleen cells of dinitrophenyl keyhole limpet hemocyanin (DNPKLH) primed and boosted mice produced a nonantigen-specific helper factor upon in vitro challenge with DNPKLH. This helper factor displays all of the biological characteristics so far described for TRF produced by allogeneic or Concanavalin A stimulation of mouse spleen cells. It restores the primary anti-SRBC response in nude spleen cultures following the same kinetics of action as T-cell-replacing factor (TRF). Conversely, TRF restores the primary in vitro immune response of nude spleen cultures to DNPKLH. TRF also restores the secondary anti-hapten IgG response of T-cell-deprived spleen cell cultures derived from DNPKLH primed and boosted mice. Here the need for carrier specificity is fully overcome. The data therefore suggest that TRF, as a nonantigen-specific maturation signal, is involved in the primary and secondary immune responses to both particulate and soluble antigens.

摘要

用二硝基苯基钥孔戚血蓝蛋白(DNPKLH)致敏并加强免疫的小鼠的脾细胞,在体外用DNPKLH攻击时产生了一种非抗原特异性辅助因子。这种辅助因子表现出了迄今所描述的由同种异体或刀豆球蛋白A刺激小鼠脾细胞产生的转移因子(TRF)的所有生物学特性。它能在裸脾培养物中恢复初次抗绵羊红细胞(SRBC)反应,其作用动力学与T细胞替代因子(TRF)相同。相反,TRF能恢复裸脾培养物对DNPKLH的体外初次免疫反应。TRF还能恢复来自用DNPKLH致敏并加强免疫的小鼠的T细胞缺失脾细胞培养物的二次抗半抗原IgG反应。在这里,对载体特异性的需求被完全克服。因此,数据表明TRF作为一种非抗原特异性成熟信号,参与了对颗粒性和可溶性抗原的初次和二次免疫反应。
