摘要:
The present invention provides a method of increasing expression of a promoter distal gene in a virus of the order Mononegavirales, and a recombinant virus constructed by such method. Also provided is a method of attenuating a virus of the order Mononegavirales, and of constructing an attenuated virus useful for a vaccine.
摘要:
The disclosure concerns compositions containing inactivated but therapeutically active biopharmaceuticals, and methods for formulation thereof. Biopharmaceuticals are encapsulated and immobilized in dry amorphous carbohydrate-glass and irradiated for inactivation while in the dry state. The resulting compositions provide ambient-temperature stable, therapeutically active but inactivated biopharmaceuticals for use in vaccines and other applications.
摘要:
Rabies Virus compositions and methods are provided. The full-length sequence of Rabies Virus strain Evelyn-Rokitnicki-Abelseth (ERA) is disclosed. A reverse genetics system for producing recombinant ERA virus and derivatives thereof is provided, along with compositions including ERA and/or ERA derivative strain viruses, nucleic acids and/or proteins. In some instances, the compositions are immunogenic compositions useful for the pre- or post-exposure treatment of Rabies Virus.

摘要:
Live, attenuated recombinant rabies virus vaccines are generated using reverse genetics to combine the antigenic determinants that render the rabies virus non-pathogenic with the determinants that are responsible for the elicitation of an effective anti-rabies immune response. These vaccines do not affect the antigenic, and therefore the immunogenic, properties of the virus. The present invention further relates to recombinant rabies virus vaccines that express a pro-apoptotic protein, such as cytochrome c, to increase the capacity to induce apoptosis, thereby enhancing the protective immunity against rabies. This new generation of live rabies virus vaccines represents a safe and effective approach to the eradication of rabies in wildlife, and subsequently humans and livestock.

摘要:
Recombinant rabies viruses in which the arginine residue of the glycoprotein (G) at amino acid position 333 is exchanged, renders these viruses nonpathogenic for immunocompetent mammals regardless of the route of infection. Some of these recombinant rabies viruses after several serial virus passages in newborn mice can become pathogenic for adult mice. The reversion to the pathogenic phenotype is associated with a thymidine to adenosine mutation (TôA) at position 639 of the G gene, which results in an asparagine to lysine exchange at position 194 of G. The codon at position 637-639 was changed by site directed mutagenesis to replace asparagine at position 194 by an amino acid that minimized the possibility for an AsnôLys exchange at amino acid position 194 of G and prevents reversion to a pathogenic form of the virus.
摘要:
The present invention describes recombinant RV mutants comprising a combine mutation in two different parts of the viral genome, involving the P and the G genes. The mutations in the P gene preferably encompass residues 139 to 170, more preferably residue 139 to 149, most preferably residues 143-149. The mutation can be a substitution or deletion of one or more amino acids in the above region, as well as combinations of deletion and substitution.
