摘要

采用酶联免疫吸附法测定人血清对重组结核分枝杆菌抗原的反应性。结果表明,结核(TB)患者对PE_PGRS和PPE蛋白或Ag85B和肝素结合血凝素(HBHA)重组抗原不产生强烈的体液应答。相反,与对照组相比,从结核病患者获得的血清强烈识别纯化甲基化HBHA。

Patients with pulmonary tuberculosis develop a strong humoral response against methylated heparin-binding hemagglutinin.

Reactivities of human sera against selected recombinant Mycobacterium tuberculosis antigens were assessed by enzyme-linked immunosorbent assay. The results obtained indicate that patients with tuberculosis (TB) do not develop a strong humoral response against PE_PGRS and PPE proteins or against the Ag85B and heparin-binding hemagglutinin (HBHA) recombinant antigens. Conversely, purified methylated HBHA was strongly recognized by sera obtained from TB patients compared to controls.
