Abstract

Antibody responses during tuberculosis were analyzed by an enzyme-linked immunosorbent assay with a panel of 10 protein antigens of Mycobacterium tuberculosis. It was shown that serum immunoglobulin G antibodies were produced against a variety of M. tuberculosis antigens and that the vast majority of sera from tuberculosis patients contained antibodies against one or more M. tuberculosis antigens. The number and the species of serologically reactive antigens varied greatly from individual to individual. In a given serum, the level of specific antibodies also varied with the antigen irrespective of the total number of antigens recognized by that particular serum. These findings indicate that person-to-person heterogeneity of antigen recognition, rather than recognition of particular antigens, is a key attribute of the antibody response in tuberculosis.

摘要

采用酶联免疫吸附测定法,利用一组10种结核分枝杆菌蛋白抗原,对结核病患者的抗体反应进行了分析。结果显示,血清免疫球蛋白G抗体针对多种结核分枝杆菌抗原产生,并且绝大多数结核病患者血清中含有针对一种或多种结核分枝杆菌抗原的抗体。血清学反应性抗原的数量和种类在个体之间差异很大。在给定的血清中,特异性抗体水平也因抗原而异,与该特定血清识别的抗原总数无关。这些发现表明,抗原识别的个体间异质性而非对特定抗原的识别,是结核病抗体反应的关键属性。
