    • A combination of adenoviral and retroviral vectors used to construct second generation packaging cells that deliver marker genes to target cells is described. A vector based upon Moloney murine leukemia virus (MLV) was used to deliver marker genes, and an adenovirus-based delivery system was used to deliver MLV structural genes (gagpol and env) to cultured cells. The procedure transformed the cells into new retroviral producer cells, which generate replication-incompetent retroviral particles in the culture supernatant for transferring marker genes to target cells. The titer of the retroviral-containing supernatant generated from the second generation producer cells reached above 105 cfu/ml, which is comparable to the MLV-based producer cell lines currently used in human gene therapy trials. The vector and procedures are adaptable for experimental human gene therapy in which the new producer cells are transplanted into patients for continuous gene transfer.
    • 描述了用于构建将标记基因递送至靶细胞的第二代包装细胞的腺病毒和逆转录病毒载体的组合。 使用基于莫洛尼鼠白血病病毒(MLV)的载体递送标记基因,并且使用基于腺病毒的递送系统将MLV结构基因(gagpol和env)递送至培养的细胞。 该过程将细胞转化为新的逆转录病毒生产细胞,其在培养上清液中产生复制不足的逆转录病毒颗粒,用于将标记基因转移至靶细胞。 从第二代生产细胞产生的含有逆转录病毒的上清液的滴度高于105cfu / ml,这与目前在人类基因治疗试验中使用的基于MLV的生产细胞系相当。 载体和程序适用于实验性人类基因治疗,其中新的生产细胞被移植到患者中用于连续基因转移。

    • The present invention features helper-dependent adenoviral vector elements, and helper adenoviral elements, that enhance the production and isolation of helper-dependent adenoviral vectors. Such elements include a modified packaging signal having low homology to, and preferably less activity than, a wild-type packaging signal, an E4 non-coding segment directly joined to the 5' ITR that confers a selective advantage, and stuffer region(s) that provide a helper-dependent adenoviral vector with a GC content of about 50 % to about 60 %. The modified packaging signal is preferably used in a helper virus to decrease recombination and generation of the virus. The E4 non-coding segment and the stuffer region(s) are preferably used in a helper-dependent adenoviral vector to provide the vector with a growth advantage over a helper virus.
