    • The present invention provides a method for preparing HSV vectors. The method comprises co-transfecting a source vector and a mutating cassette together into a population of appropriate host cells, such that homologous recombination occurs between the mutating cassette and the source vector whereby the mutating cassette replaces a region of the HSV genome. The mutating cassette has a unique restriction site not present in the sequence of the vector. The method further comprises plaquing the co-transfected host cells, selecting plaques in which recombination has occurred between the source vector and the mutating cassette, and isolating the viral DNA from the plaques. The isolated viral DNA is digested with a restriction endonuclease appropriate for cleaving the viral DNA at the unique restriction site within the mutating cassette to produce two viral polynucleotides. Following purification, the two viral polynucleotides can be ligated to form an HSV vector comprising the two viral polynucleotides. Alternatively, the two isolated viral polynucleotides can be recombined with an insertion cassette to form an HSV vector comprising the insertion cassette at the former locus of the unique restriction site. The present invention further provides a mutant vector, particularly an HSV vector constructed in accordance with the method for the present invention. The present invention further provides a multigene HSV vector, particularly a multigene HSV vector for cancer therapy.
    • 本发明提供一种HSV载体的制备方法。 该方法包括将源载体和突变盒共同转染到合适的宿主细胞群体中,使得在突变盒和源载体之间发生同源重组,由此突变盒替代HSV基因组的区域。 突变盒具有不存在于载体序列中的唯一限制性位点。 该方法还包括将共转染的宿主细胞进行筛选,选择在源载体和突变盒之间已经发生重组的斑块,并从噬斑中分离病毒DNA。 分离的病毒DNA用限制性内切核酸酶消化,其适用于在突变盒内的独特的限制性位点切割病毒DNA,以产生两个病毒多核苷酸。 纯化后,可以连接两种病毒多核苷酸以形成包含两种病毒多核苷酸的HSV载体。 或者,两个分离的病毒多核苷酸可以与插入盒重组以形成包含在唯一限制性位点前一位点的插入盒的HSV载体。 本发明还提供了突变载体,特别是根据本发明的方法构建的HSV载体。 本发明还提供了多基因HSV载体,特别是用于癌症治疗的多基因HSV载体。

    • Methods for treating a connective tissue disorder by introducing at least one gene encoding a product into at least one target cell of a mammalian host for use in treating the mammalian host are disclosed. These methods include employing recombinant techniques to produce a vector molecule containing the DNA sequence encoding for the product and infecting the target cell of the mammalian host using the vector. The injection can be done in vivo, by directly injecting the vector into the host, or can be done in vitro by transfecting a population of cultured target cells with the vector and transplanting them each into the host. Nonviral means can also be used to introduce the DNA sequence to the host. Administration of more than one gene of interest results in an enhanced therapeutic benefit. Also disclosed is a method for treating a connective tissue disorder by introducing at least one gene encoding a product into at least one target cell of a joint of a host for use in treating multiple joints of the host. Injection of a vector molecule containing the DNA sequence encoding for a product of interest, or non-viral introduction of such a DNA sequence, to one join of a mammalian host results in a therapeutic benefit in that joint as well as other joints in the host
