    • Recombinant parainfluenza virus (PIV) are provided in which expression of the C, D and/or V translational open reading frame(s) (ORFs) is reduced or ablated to yield novel PIV vaccine candidates. Expression of the C, D and/or V ORF(s) is reduced or ablated by modifying a recombinant PIV genome or antigenome, for example by introduction of a stop codon, by a mutation in an RNA editing site, by a mutation that alters the amino acid specified by an initiation codon, or by a frame shift mutation in the targeted ORF(s). Alternatively, the C, D and/or V ORF(s) is deleted in whole or in part to render the protein(s) encoded thereby partially or entirely non-functional or to disrupt protein expression altogether. C, D and/or V ORF(s) deletion and knock out mutants possess highly desirable phenotypic characteristics for vaccine development. These deletion and knock out mutations changes specify one or more desired phenotypic changes in the resulting virus or subviral particle. Vaccine candidates are generated that show a change in viral growth characteristics, attenuation, plaque size, and/or a change in cytopathogenicity, among other novel phenotypes. A variety of additional mutations and nucleotide modifications are provided within the C, D and/or V ORF(s) deletion or ablation mutant PIV of the invention to yield desired phenotypic and structural effects.
    • 提供了重组副流感病毒(PIV),其中C,D和/或V翻译开放阅读框(ORF)的表达被降低或消融以产生新型PIV疫苗候选物。 C,D和/或V ORF的表达通过修饰重组PIV基因组或反义基因组,例如通过引入终止密码子,通过RNA编辑位点中的突变,通过改变的突变来降低或消除 由起始密码子指定的氨基酸或靶向ORF中的帧位移突变。 或者,C,D和/或V ORF全部或部分缺失,以使由此编码的蛋白质部分或完全不起作用或完全破坏蛋白质表达。 C,D和/或V ORF(s)缺失和敲除突变体对疫苗开发具有非常需要的表型特征。 这些缺失和敲除突变变化指定了所得病毒或亚病毒颗粒中的一种或多种期望的表型变化。 产生疫苗候选物,其显示病毒生长特征,衰减,斑块大小和/或细胞致病性变化以及其他新型表型之间的变化。 本发明的C,D和/或V ORF缺失或消融突变体PIV中提供了多种其它突变和核苷酸修饰,以产生所需的表型和结构效果。

    • Chimeric human-bovine respiratory syncytial virus (RSV) are infectious and attenuated in humans and other mammals and useful in vaccine formulations for eliciting an anti-RSV immune response. Also provided are isolated polynucleotide molecules and vectors incorporating a chimeric RSV genome or antigenome which includes a partial or complete human or bovine RSV "background" genome or antigenome combined or integrated with one or more heterologous gene(s) or genome segment(s) of a different RSV strain. Chimeric human-bovine RSV of the invention include a partial or complete "background" RSV genome or antigenome derived from or patterned after a human or bovine RSV strain or subgroup virus combined with one or more heterologous gene(s) or genome segment(s) of a different RSV strain or subgroup virus to form the human-bovine chimeric RSV genome or antigenome. In preferred aspects of the invention, chimeric RSV incorporate a partial or complete bovine RSV background genome or antigenome combined with one or more heterologous gene(s) or genome segment(s) from a human RSV. Genes of interest include any of the NS1, NS2, N, P, M, SH, M2(ORF1), M2(ORF2), L, F or G genes or a genome segment including a protein or portion thereof. A variety of additional mutations and nucleotide modifications are provided within the human-bovine chimeric RSV of the invention to yield desired phenotypic and structural effects.
