We investigated apoptosis induced by herpes simplex virus type 1 (HSV-1) in cord blood T lymphocytes by using agarose gel electrophoresis, DNA content analysis and the terminal deoxytransferase (TdT)- mediated dUTP nick end-labeling (TUNEL) method. DNA fragmentation and the hypodiploid fraction in the cell cycle were both increased in HSV-1-infected CD4 and CD8 lymphocytes stimulated with phytohaemagglutinin (PHA) compared to mock- infected lymphocytes. HSV-1 antigen glycoprotein D (gD) and regulatory protein ICP27 were detected in 8-18% of the hypodiploid fraction of PHA-stimulated, HSV-1-infected lymphocytes. Apoptosis was induced not only in HSV-1 antigen-expressing cells but also in cells not expressing detectable viral proteins. Addition of anti-Fas antibody, anti-Fas-ligand antibody or a mixture of both had no effect on HSV-1-induced apoptosis, indicating that the Fas-Fas-ligand pathway did not contribute to HSV-1-induced apoptosis.

我们通过琼脂糖凝胶电泳、DNA 含量分析和末端脱氧转移酶 (TdT) 介导的 dUTP 缺口末端标记 (TUNEL) 方法研究了 1 型单纯疱疹病毒 (HSV-1) 诱导的脐带血 T 淋巴细胞凋亡。与模拟感染的淋巴细胞相比，用植物血凝素（PHA）刺激的HSV-1感染的CD4和CD8淋巴细胞中DNA断裂和细胞周期中的亚二倍体分数均增加。在 PHA 刺激的 HSV-1 感染淋巴细胞的 8-18% 亚二倍体部分中检测到 HSV-1 抗原糖蛋白 D (gD) 和调节蛋白 ICP27。细胞凋亡不仅在表达 HSV-1 抗原的细胞中被诱导，而且在不表达可检测到的病毒蛋白的细胞中也被诱导。添加抗Fas抗体、抗Fas配体抗体或两者的混合物对HSV-1诱导的细胞凋亡没有影响，表明Fas-Fas配体途径对HSV-1诱导的细胞凋亡没有贡献。
