    摘要: Two recently characterized live attenuated HPIV1 vaccine candidates, rHPIV1-CR84G/Δ170HNT553ALY942A and rHPIV1-CR84G/Δ170HN-T553ALΔ1710-11, which contain temperature sensitive (ts) attenuating (att) and non-ts att mutations, were evaluated in a Human Airway Epithelium (HAE) model culture system and in vivo in African Green monkeys (AGM). The vaccine candidates were highly restricted in growth in HAE at permissive (32° C.) and restrictive (37° C.) temperatures. The viruses grew slightly better at 37° C. than at 32° C., and rHPIV1-CR84G/Δ170HNT553A-LY942A was less attenuated than rHPIV1-CR84G/Δ170HNT553ALΔ1710-11. The level of replication in HAE correlated with that observed in African Green monkeys, suggesting that the HAE model is useful as a tool for pre-clinical evaluation of HPIV1 vaccines. A live attenuated HPIV1 vaccine candidate having a normal P/C gene structure of overlapping P and C open reading frames, but does not express any functional C protein, is found to highly attenuated in AGMs, and provides a significant immune response in AGMs.

    摘要: Chimeric human-bovine parainfluenza viruses (PIVs) are infectious and attenuated in humans and other mammals and useful individually or in combination in vaccine formulations for eliciting an immune response to PIV or other pathogens. Also provided are isolated polynucleotide molecules and vectors incorporating a chimeric PIV genome or antigenome which includes a partial or complete human or bovine PIV “background” genome or antigenome combined or integrated with one or more heterologous gene(s) or genome segment(s) of a different PIV. Chimeric human-bovine PIV of the invention include a partial or complete “background” PIV genome or antigenome derived from or patterned after a human or bovine PIV virus combined with one or more heterologous gene(s) or genome segment(s) of a different pathogen, including different PIV virus to form the human-bovine chimeric PIV genome or antigenome.

    摘要: Attenuated, recombinant negative stranded RNA viruses suitable for vaccine use are produced from one or more isolated polynucleotide molecules encoding the virus. A recombinant genome or antigenome of the subject virus is modified to encode a mutation within a recombinant protein of the virus at one or more amino acid positions(s) corresponding to a site of an attenuating mutation in a heretologous, mutant negative stranded RNA virus. A similar attenuating mutation as identified in the heterologous negative stranded RNA virus is thus incorporated at a corresponding site within the recombinant virus to confer an attenuated phenotype on the recombinant virus. The attenuating mutation incorporated in the recombinant virus may be identical or conservative in relation to the attenuating mutation identified in the heterologous, mutant virus. By the transfer of mutations into recombinant negative stranded RNA viruses in this matter, candidate vaccine viruses are engineered to elicit a desired immune response against a subject virus in a host susceptible to infection thereby.
