    • A method for producing in vivo packaged recombinant adenovirus vectors is provided. The recombinant Ad vectors do not contain any Adenovirus genes and are therefore useful for gene therapy. The recombinant Adenovirus vectors are packaged in vivo using a helper virus which is itself very inefficiently packaged, providing a recombinant viral preparation with very little or no contamination with helper virus. In particular, the method makes use of a helper virus in which the packaging site can be easily excised in vivo by recombination mediated by a recombinase. The helper virus is also useful for the in vivo construction of new recombinant adenovirus vectors containing substitutions in the E1 or other adenoviral region.
    • 提供了一种生产体内包装的重组腺病毒载体的方法。 重组Ad载体不含有任何腺病毒基因,因此可用于基因治疗。 重组腺病毒载体使用本身非常低效包装的辅助病毒在体内包装,提供与辅助病毒很少或没有污染的重组病毒制剂。 特别地,该方法利用辅助病毒,其中可以通过由重组酶介导的重组在体内容易地切除包装位点。 辅助病毒也可用于体内构建在E1或其他腺病毒区域中含有取代的新的重组腺病毒载体。
