Abstract

Delayed hypersensitivity (DH) and antibody reactions to the carrier and to the hapten have been studied in guinea-pigs immunized with different doses of highly substituted dinitrophenyl-human gamma-globulins (DNP56-HGG) in Freund's complete adjuvant (FCA). The results confirm that DH reactions are specific for the carrier while antibody-mediated reactions are specific for the hapten in the early stages of the immune response. Later in the response, however, DH reactions to the hapten as well as a transient humoral reaction to the carrier could be observed. T cells specific for the hapten and B cells specific for the carrier are therefore triggered after a single infection of a highly substituted hapten-carrier conjugate in FCA. Their regulatory functions in the immune response to hapten-carrier conjugates are discussed.

摘要

在豚鼠中,研究了用不同剂量的高取代二硝基苯基 - 人γ - 球蛋白(DNP56 - HGG)在弗氏完全佐剂(FCA)中免疫后,对载体和半抗原的迟发型超敏反应(DH)及抗体反应。结果证实,在免疫反应早期,DH反应对载体具有特异性,而抗体介导的反应对半抗原有特异性。然而,在反应后期,可观察到对半抗原的DH反应以及对载体的短暂体液反应。因此,在FCA中单次注射高取代半抗原 - 载体偶联物后,会触发对半抗原有特异性的T细胞和对载体有特异性的B细胞。讨论了它们在对半抗原 - 载体偶联物免疫反应中的调节功能。
