Abstract

Four different methods to test antibody-dependent cellular cytotoxicity (ADCC) against Epstein-Barr virus (EBV) determined antigens were analysed. It was found that optimal ADCC was obtained if viral antigens were present during the cytotoxicity reaction and that killing probably was mediated by EBV-related immune-complexes forming Fc-Fc receptor bridges between Fc receptor-bearing effector cells and Fc receptor-bearing target cells. Only lymphoid target cells with a high expression of Fc receptors were found to be susceptible in this particular system.

摘要

分析了四种针对爱泼斯坦-巴尔病毒(EBV)确定抗原检测抗体依赖性细胞毒性(ADCC)的不同方法。发现如果在细胞毒性反应期间存在病毒抗原,则可获得最佳ADCC,并且杀伤可能是由EBV相关免疫复合物介导的,这些复合物在携带Fc受体的效应细胞和携带Fc受体的靶细胞之间形成Fc-Fc受体桥。在这个特定系统中,仅发现具有高Fc受体表达的淋巴样靶细胞是易感的。
