Animals were rendered tolerant to human albumin and were then immunized with azo derivatives of human albumin which differed in the number of hapten groups per molecule and in the extent of conformational change. The incidence and specificity of the resulting antibody response was studied and the presence of antibody to azo groups and to conformationally altered protein determinants was demonstrated. Reactivity with the tolerance-inducing antigen was shown to be due to antibodies directed against conformationally altered protein determinants. The difference in the response of tolerant animals to hapten-poor and hapten-rich derivatives was attributed to the extent of conformational alteration. A genetic factor appeared to be implicated in the capacity of tolerant animals to respond to an antigen which cross-reacts with tolerance-inducing macromolecules.
使动物对人白蛋白产生耐受性,然后用每分子中半抗原基团数量不同且构象变化程度不同的人白蛋白偶氮衍生物进行免疫。研究了由此产生的抗体反应的发生率和特异性,并证明了存在针对偶氮基团和构象改变的蛋白质决定簇的抗体。与诱导耐受性抗原的反应性被证明是由于针对构象改变的蛋白质决定簇的抗体。耐受性动物对半抗原含量低和半抗原含量高的衍生物反应的差异归因于构象改变的程度。一个遗传因素似乎与耐受性动物对与诱导耐受性大分子发生交叉反应的抗原的反应能力有关。
