Herpes simplex virus (HSV)-specific CD8+ cytotoxic T lymphocytes (CTL) have rarely been detected in humans, presumably because of virus-induced mechanisms that downregulate major histocompatibility complex class I expression. We have developed a method that has allowed us to consistently demonstrate HSV-specific CD8+ precursor CTL (pCTL) from HSV type 1- and 2-seropositive persons. Major histocompatibility complex-restricted HSV-specific CD8+ pCTL were found in 10 consecutively tested HSV type 1- and 2-seropositive subjects at frequencies ranging from 1 in 21,000 to 1 in 300 (median, 1 in 6,000) versus a pCTL frequency of 1 in 100,000 in HSV-seronegative donors. These results suggest that CD8+ CTL are important effector cells in resolving HSV lesions.
单纯疱疹病毒(HSV)特异性CD8 + 细胞毒性T淋巴细胞(CTL)在人类中很少被检测到,推测是由于病毒诱导的机制下调了主要组织相容性复合体I类的表达。我们开发了一种方法,使我们能够持续从1型和2型HSV血清阳性个体中检测到HSV特异性CD8 + 前体细胞毒性T淋巴细胞(pCTL)。在连续检测的10名1型和2型HSV血清阳性受试者中发现了主要组织相容性复合体限制的HSV特异性CD8 + pCTL,频率范围为21,000分之一至300分之一(中位数为6,000分之一),而HSV血清阴性供体中的pCTL频率为100,000分之一。这些结果表明,CD8 + CTL是解决HSV损伤的重要效应细胞。
