    摘要: The present invention provides HIV-derived lentivectors which are multiply modified to create highly safe, efficient, and potent vectors for expressing transgenes for gene therapy. The lentiviral vectors comprise various combinations of an inactive central polypurine tract, a stuffer sequence, which may encode drug susceptibility genes, and a mutated hairpin in the 5′ leader sequence that substantially abolishes replication. These elements are provided in conjunction with other features of lentiviral vectors, such as a self-inactivating configuration for biosaftey and promoters such as the EF1α promoter as one example. Additional promoters are also described. The vectors can also comprise additional transcription enhancing elements such as the wood chuck hepatitis virus post-transcriptional regulatory element. These vectors therefore provide useful tools for genetic treatments for inherited and acquired disorders, gene-therapies for cancers and other disease, the creation of industrial and experimental production systems utilizing transformed cells, as well as for the study of basic cellular and genetic processes.

    摘要: The invention provides improved methods and products based on adenoviral materials which can advantageously be used in gene therapy. In one aspect, an adenoviral vector is provided having no overlap with a suitable packaging cell line. The suitable packaging cell line is another aspect. The combination excludes the possibility of homologous recombination, thereby excluding the possibility of the formation of replication competent adenovirus. Another aspect embodies an adenovirus based helper construct which by its size is incapable of being encapsidated. This helper virus can be transferred into any suitable host cell making it a packaging cell. Furthermore, a number of useful mutations to adenoviral based materials and combinations of such mutations are disclosed, all of which have in common the safety of the methods and the products, in particular avoiding the production of replication competent adenovirus and/or interference with the immune system.

    摘要: The invention provides a lentiviral vector capable of inhibiting the expression of at least one target gene. A lentiviral vector of the invention encompasses a first nucleic acid sequence derived from a target gene transcript and a second nucleic acid sequence corresponding to the reverse complement of said first nucleic acid sequence. A lentiviral vector of the invention capable of inhibiting the expression of a target gene is useful in therapeutic applications to inactivate disease-associated transcripts and thereby reduce the severity of inherited metabolic, infectious or malignant conditions. Methods for inhibiting one or more target genes in a cell as well as methods for producing a non-human mammal in which the expression of one or more target genes is inhibited also are provided by the present invention.
