    • The present invention relates to cells for the production of helper dependent adenoviral vectors, including at least the following genic units: a first genic unit comprising an adenovirus defective genome having the inverted terminal repeats in head-to-tail configuration, the encapsidation signal inactivated, and at least one of the non-structural regions inactivated; a second genic units comprising at least one inducible promoter and at least one of the regions inactivated in the first genic unit, said regions being under the control of said inducible promoter; whereby following the activation of the inducible promoter of the second genic unit and the infection of the cells with said helper dependent adenoviral vectors, the first genic unit and the second genic unit enable the production of said helper dependent defective adenoviral in said cells in absence of helper.
    • 本发明涉及用于产生辅助性依赖性腺病毒载体的细胞,其包括至少以下基因单元:第一基因单元,其包含具有头对尾构型中的反向末端重复序列的腺病毒缺陷基因组,所述壳化信号失活, 并且至少一个非结构区域失活; 第二基因单元,其包含至少一个诱导型启动子和在第一基因单元中灭活的区域中的至少一个,所述区域在所述诱导型启动子的控制之下; 由此在第二基因单元的诱导型启动子的激活和所述辅助依赖性腺病毒载体的细胞感染之后,第一基因单元和第二基因单元使得能够在所述细胞中产生所述辅助依赖性缺陷型腺病毒, 帮手。
