    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.

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 (T→A) 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 Asn→Lys exchange at amino acid position 194 of G and prevents reversion to a pathogenic form of the virus.

    摘要: Methods and compositions are provided for the use of rabies virusneutralizing antibodies for postexposure prophylactic treatment of subjects exposed to rabies virus. Compositions comprising mixtures of rabies virusneutralizing antibodies, as well as nucleotide and amino acid sequences encoding these antibodies, can be used in the treatment of subjects exposed to rabies virus. The invention also provides methods of producing recombinant rabies virus-neutralizing human antibodies in mammalian cells using recombinant expression vectors.
