Abstract

The present study characterized the cytotoxic capabilities of human T lymphocyte subpopulations against human red blood cells (HRBC) and autologous lymphoid cells in an antibody-dependent cellular cytotoxicity (ADCC) assay. T cells bearing Fc receptors for immunoglobulin IgG (TG) were capable of lysis of antibody-coated HRBC and autologous lymphoid cells while T cells with surface Fc receptors for IgM (TM) displayed no ADCC activity TG-cell mediated ADCC could be inhibited by blockage of surface Fc receptors following treatment with aggregated Ig. Null cells and low-affinity E-rosette forming cells were also capable of similar ADCC activity against these targets.

摘要

本研究在抗体依赖性细胞毒性(ADCC)试验中,对人T淋巴细胞亚群针对人红细胞(HRBC)和自体淋巴细胞的细胞毒性能力进行了表征。带有免疫球蛋白IgG的Fc受体的T细胞(TG)能够裂解包被抗体的HRBC和自体淋巴细胞,而带有IgM表面Fc受体的T细胞(TM)则无ADCC活性。用聚集Ig处理后,通过阻断表面Fc受体可抑制TG细胞介导的ADCC。裸细胞和低亲和力E花环形成细胞对这些靶标也具有类似的ADCC活性。
