    Abstract: 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.

    Abstract: Use of a paramyxovirus vector makes it possible to transfer a nucleic acid into a blood vessel at a high efficiency even by exposing to the vector within a short period of time. Namely, a paramyxovirus vector to be used for transferring a nucleic acid into vascular cells and a nucleic acid transfer method with the use of this virus vector are provided. The gene transfer efficiency into the vascular media layer is significantly elevated by treating the blood vessel with a protease. The expression of the transferred gene remains stable over a long time in the vascular cells. Use of this method makes it possible to efficiently transfer a gene within a short period of time into the vascular cavity, media, tunica tissues, etc. in gene therapy.

    Abstract: Virus vectors of the family Paramyxoviridae in which the transcription initiation sequence has been modified and thus the expression of genes located downstream thereof has been modified; a process for producing the same; and use of the same. By measuring the transcription initiation efficiency of each gene carried by Sendai viruses, it is clarified that the transcription initiation sequence of F gene has a significantly lower ability to promote the transcription than the three other transcription initiation sequences. When the transcription initiation sequence of the F gene of wild type Sendai virus is substituted by the transcription initiation sequence of the P/M/HN genotype showing a high efficiency, the F gene of the resultant Sendai virus mutant and genes located downstream thereof show elevated expression doses. It is also found out that this mutant proliferates more quickly than the wild type. The above-described vectors are useful in producing medicinal compositions and vaccines.
