Abstract

A defective herpes simplex virus 1 (HSV-1) vector, pHSVlac, has been developed that contains a transcription unit that places the Escherichia coli lacZ gene under the control of the HSV-1 immediate early 4/5 promoter. The vector pHSVlac was propagated with the HSV-1 temperature-sensitive mutant ts K as helper virus. Infection of neurons from rat superior cervical ganglia and dorsal root ganglia in primary culture resulted in stable expression of high levels of beta-galactosidase without cell death. These HSV-1 vectors should be useful for introducing genes into postmitotic cells, such as neurons, in vitro and in vivo.

摘要

一种有缺陷的单纯疱疹病毒1型(HSV-1)载体pHSVlac已被研发出来,它包含一个转录单元,该转录单元使大肠杆菌lacZ基因置于HSV-1立即早期4/5启动子的控制之下。载体pHSVlac与HSV-1温度敏感突变体tsK作为辅助病毒一起增殖。对原代培养的大鼠颈上神经节和背根神经节中的神经元进行感染,导致高水平的β-半乳糖苷酶稳定表达且无细胞死亡。这些HSV-1载体在体外和体内将基因导入有丝分裂后细胞(如神经元)中应该是有用的。
