    • This invention provides recombinant, replication-competent Rhabdovirus vaccine strain-based expression vectors for expressing heterologous viral antigenic polypeptides such as immunodeficiency virus envelope proteins or subparts thereof. An additional transcription stop/start unit within the Rhabdovirus genome is inserted to express the heterologous antigenic polypeptides. The HIV-1 gp160 protein is stably and functionally expressed, as indicated by fusion of human T cell-lines after infection with the recombinant RVs. Inoculation of mice with the recombinant Rabies viruses expressing HIV-1 gp160 induces a strong humoral response directed against the HIV-1 envelope protein after a single boost with an isolated recombinant HIV-1 gp120 protein. Moreover, high neutralization titers, up to 1:800, against HIV-1 are detected in the mouse sera. These recombinant viral vectors expressing viral antigenic polypeptides provide useful and effective pharmaceutical compositions for the generation of viral-specific immune responses.
    • 本发明提供用于表达异源病毒抗原性多肽(例如免疫缺陷病毒包膜蛋白或其子部分)的重组,基于复制能力的基于弹状病毒基因毒株的表达载体。 插入Rhabdovirus基因组内的另外的转录停止/起始单位以表达异源抗原多肽。 HIV-1 gp160蛋白质是稳定和功能表达的,如通过重组RV感染后的人T细胞系的融合所表明的。 用重组的表达HIV-1 gp160的狂犬病病毒接种小鼠,用分离的重组HIV-1 gp120蛋白单次加强后,诱导针对HIV-1包膜蛋白的强烈体液应答。 此外,在小鼠血清中检测到针对HIV-1的高达1:800的高中和滴度。 这些表达病毒抗原多肽的重组病毒载体提供了用于产生病毒特异性免疫应答的有用和有效的药物组合物。

    • A mutant virus is provided which contains a mutation at a phosphorylation site in one or more of the proteins of the virus, which mutation causes the virus to be attenuated, and therefore, an improved vaccine composition can be produced therewith. The invention also relates to vaccine compositions which contain the mutant virus, as well as to methods of inducing an immune response, and of protecting mammals from infection by rabies virus. Also included in the invention are methods of producing the mutant virus and mutant viral proteins, including producing the mutant virus in a host cell which produces or even overproduces a wild-type counterpart of the mutant viral protein, which complements the other viral proteins such that production of the mutant viral particle is optimized. The invention also includes those host cells in which viral production is optimized, as well as vaccine compositions including the viral proteins, either alone or in combination with the intact virus, and to methods of inducing an immune response or protecting a mammal from infection, using the same. Also included in the invention are vectors suitable for delivering a gene to a cell of a human or animal, as well methods of delivery thereof.
