Abstract

In the present studies we have confirmed that the random copolymer of L-glutamic acid50-L-tyrosine50 (GT) fails to induce an antibody response in a large number of inbred strains of mice. Nevertheless, GT complexed to methylated bovine serum albumin (MBSA) elicits a GT-specific IgG PFC response in vivo. Furthermore, injection of BALB/c mice with 10 to 100 mug of GT specifically decreases their ability to develop anti-GT PFC responses to a subsequent challenge with GT-MBSA. GT-specific tolerance can be transferred to normal, syngeneic recipients by spleen cells or thymocytes of GT-primed animals. These results indicate that the stimulation of suppressor cells can be observed in nonresponder mice with another synthetic polypeptide besides GAT. Various parameters of GT-specific immunosuppression in BALB/c mice are described. The application of these techniques to the study of the genetic factors controlling the stimulation of specific immune suppression is discussed.

摘要

在目前的研究中,我们已证实,L-谷氨酸50-L-酪氨酸50(GT)的无规共聚物在大量近交系小鼠中不能诱导抗体应答。然而,与甲基化牛血清白蛋白(MBSA)复合的GT在体内可引发GT特异性IgG空斑形成细胞(PFC)应答。此外,给BALB/c小鼠注射10至100μg的GT可特异性降低其对随后用GT-MBSA攻击产生抗GT PFC应答的能力。GT特异性耐受性可通过经GT免疫动物的脾细胞或胸腺细胞转移至正常同基因受体。这些结果表明,除了GAT之外,在无应答小鼠中用另一种合成多肽也可观察到抑制细胞的刺激。本文描述了BALB/c小鼠中GT特异性免疫抑制的各种参数。讨论了将这些技术应用于研究控制特异性免疫抑制刺激的遗传因素。
