(EN) The invention relates to a recombinant herpes simplex virus as well as a construction method and application thereof. According to the recombinant herpes simplex virus as well as the construction method and application thereof, the recombinant virus is constructed by knocking out an ICP34.5 gene and an ICP47 gene of an I-type herpes simplex virus and inserting an IFN-gamma expression sequence into a UL23 gene, the neurotoxicity and selective infection, replication and proliferation of the recombinant virus in tumor cells can be effectively lowered, and the sensitivity to the tumor cells is improved.
(ZH) 本发明涉及一种重组单纯疱疹病毒及其构建方法和应用。本发明通过将I型单纯疱疹病毒的ICP34.5基因、ICP47基因敲除,并在UL23基因上插入IFN‑γ表达序列,构建得到的重组病毒,可有效降低其神经毒性及选择性在肿瘤细胞中感染复制增殖,并且对肿瘤细胞的敏感性提高。
