    摘要: Chimeric respiratory syncytial virus (RSV) and vaccine compositions thereof are produced by introducing one or more heterologous gene(s) or gene segment(s) from one RSV subgroup or strain into a recipient RSV backround of a different subgroup or strain. The resulting chimeric RSV virus or subviral particle is infectious and attenuated, preferably by introduction of selected mutations specifying attenuated phenotypes into a chimeric genome or antigenome to yield, for example, temperature sensitive (ts) and/or cold adapted (ca) vaccine strains. Alternatively, chimeric RSV and vaccine compositions thereof incorporate other mutations specifying desired structural and/or phenotypic characteristics in an infectious chimeric RSV. Such chimeric RSV incorporate desired mutations specified by insertion, deletion, substitution or rearrangement of one or more selected nucleotide sequence(s), gene(s), or gene segment(s) in a chimeric RSV clone. This provides a method for development of novel vaccines against diverse RSV strains by using a common attenuated backbone as a vector to express protective antigens of heterologous strains. The immune system of an individual is stimulated to induce protection against natural RSV infection, preferably in a multivalent manner to achieve protection against multiple RSV strains and/or subgroups.

    摘要: Recombinant respiratory syncytial virus (RSV) having the position of genes shifted within the genome or antigenome of the recombinant virus are infectious and attenuated in humans and other mammals. Gene shifted RSV are constructed by insertion, deletion or rearrangement of genes or genome segments within the recombinant genome or antigenome and are useful in vaccine formulations for eliciting an anti-RSV immune response. Also provided are isolated polynucleotide molecules and vectors incorporating a recombinant RSV genome or antigenome wherein a gene or gene segment is shifted to a more promoter-proximal or promoter-distal position within the genome or antigenome compared to a wild type position of the gene in the RSV gene map. Shifting the position of genes in this manner provides for a selected increase or decrease in expression of the gene, depending on the nature and degree of the positional shift.

    摘要: The invention provides recombinant viruses comprising heterologous envelope proteins capable of mediating entry of the recombinant viruses into host cells. In one embodiment, a recombinant virus of the invention is a member of the Paramyx-ovirzdae family (e.g., a respiratory syncytial virus), and the heterologous envelope protein includes the ectodomain of a baculovirus envelope protein (e.g., the GP64 protein). In some cases, the heterologous envelope protein is provided in addition to homologous envelope proteins) which may or may not be functional. The heterologous protein can provide the recombinant virus with enhanced stability (e.g., at 4° C., 22° C., or 37° C.), and allows production of high-titer virus stocks. The heterologous protein can also impart temperature sensitivity to the replication of the recombinant virus. In addition, the recombinant virus can be designed to be infectious but incapable of spreading between host cells by providing the heterologous protein by complementation in trans. These features attenuate the disease-causing potential of the recombinant virus, therefore increasing its safety of use as vaccines.
