Abstract

The genetic requirements of carrier recognition were examined in the priming and elicitation of hapten specific, T-cell mediated, delayed-type hypersensitivity (DTH) responses. It was shown that nitrophenyl acetyl-poly-(L-glu56-L-lys35-L-phe9) (NP-GLO) could prime for NP responses only in strains of mice which are Ir gene responders to GLO. In contrast to this requirement, NO-GLO could elicit an NP-specific response in NP-bovine gamma globulin primed mice, even in GLO nonresponder strains. Furthermore, the nonimmunogenic molecule, NP-GL, could elicit an NP-specific DTH response in animals primed with NP on an immunogenic carrier.

摘要

在半抗原特异性、T细胞介导的迟发型超敏反应(DTH)的启动和激发过程中,研究了载体识别的遗传需求。结果表明,硝基苯基乙酰基-聚-(L-谷氨酸56-L-赖氨酸35-L-苯丙氨酸9)(NP-GLO)仅能在对GLO为Ir基因应答者的小鼠品系中引发NP反应。与这一需求相反,NO-GLO能够在NP-牛γ球蛋白致敏的小鼠中引发NP特异性反应,即使在GLO无应答品系中也是如此。此外,非免疫原性分子NP-GL能够在免疫原性载体上用NP致敏的动物中引发NP特异性DTH反应。
