本研究的总体目标是开始表征与二恶英诱导的体液免疫抑制相关的构效关系。亚慢性暴露(14天)的2,3,8,8-四氯二苯并-p-二恶英(TCDD),类的原型,产生了抑制抗体反应的绵羊红细胞,T-依赖性抗原,和二硝基苯-菲可,T-非依赖性抗原。令人惊讶的是,用2,7-二氯二苯并-对-二恶英(DCDD)观察到类似的结果,DCDD是一种对Ah受体缺乏亲和力的二恶英同系物。相比之下,亚慢性暴露于八氯二苯并对二恶英(OCDD),另一种二恶英同系物没有亲和力的Ah受体,是缺乏活动。亚慢性接触2,3,7,8-四氯二苯并对二恶英(而非2,7-二氯二苯并对二恶英)可诱导若干肝脏参数,包括:肝脏重量、微粒体蛋白量、细胞色素P-450量、氨基比林-N-脱甲基酶活性和芳烃羟化酶活性。亚慢性暴露于2,3,7,8-TCDD或2,7-DCDD对胸腺重量无明显影响。在对胸腺没有影响的情况下,急性接触2,3,7,8-TCDD也会抑制抗体反应。
The overall objective of this investigation was to begin to characterize the structure-activity relationship associated with dioxin-induced suppression of humoral immunity. Subchronic exposure (14 days) to 2,3,8,8-tetrachlorodibenzo-p-dioxin (TCDD), the prototype of the class, produced a suppression of the antibody responses to both sheep erythrocytes, a T-dependent antigen, and dinitrophenyl-Ficoll, a T-independent antigen. Surprisingly, similar results were observed with 2,7-dichlorodibenzo-p-dioxin (DCDD), a dioxin congener lacking affinity for the Ah receptor. In contrast, subchronic exposure to octachlorodibenzo-p-dioxin (OCDD), another dioxin congener without affinity for the Ah receptor, was devoid of activity. Subchronic exposure to 2,3,7,8-TCDD, but not 2,7-DCDD, produced an induction of several liver parameters including: liver weight, amount of microsomal protein, amount of cytochrome P-450, activity of aminopyrine-N-demethylase and activity of aryl hydrocarbon hydroxylase. Subchronic exposure to 2,3,7,8-TCDD or 2,7-DCDD produced no marked changes in thymus weight. Acute exposure to 2,3,7,8-TCDD also produced suppression of the antibody response in the absence of effects on the thymus.
