20090246216 | NOVEL ATTENUATED POLIOVIRUS - A novel and stable attenuated poliovirus, which replicates in neuroblastoma cells, is produced by engineering an indigenous replication element (cre), into the 5′ non-translated genomic region and inactivating the native cre element located in the coding region of 2C (mono-crePV). The stably attenuated poliovirus replicates in a neuroblastoma model (Neuro-2a | 10-01-2009 |
20100209454 | ATTENUATED VIRUSES USEFUL FOR VACCINES - This invention provides an attenuated virus which comprises a modified viral genome containing nucleotide substitutions engineered in multiple locations in the genome, wherein the substitutions introduce synonymous deoptimized codons into the genome. The instant attenuated virus may be used in a vaccine composition for inducing a protective immune response in a subject. The invention also provides a method of synthesizing the instant attenuated virus. Further, this invention further provides a method for preventing a subject from becoming afflicted with a virus-associated disease comprising administering to the subject a prophylactically effective dose of a vaccine composition comprising the instant attenuated virus. | 08-19-2010 |
20120064113 | Novel Attenuated Poliovirus - A novel and stable attenuated poliovirus, which replicates in neuroblastoma cells, is produced by engineering an indigenous replication element (cre), into the 5′ non-translated genomic region and inactivating the native cre element located in the coding region of 2C (mono-crePV). The stably attenuated poliovirus replicates in a neuroblastoma model (Neuro-2a | 03-15-2012 |
20120269849 | ATTENUATED INFLUENZA VIRUSES AND VACCINES - The present provides attenuated influenza viruses comprising a modified viral genome containing a plurality of nucleotide substitutions. The nucleotide substitutions result in the rearrangement of preexisting codons of one or more protein encoding sequences and changes in codon pair bias. Substitutions of non-synonymous and synonymous codons may also be included. The attenuated influenza viruses enable production of improved vaccines and are used to elicit protective immune responses. | 10-25-2012 |
20140356962 | NOVEL ATTENUATED POLIOVIRUS: PV-1 MONO-CRE-X - A novel and stable attenuated poliovirus is produced by engineering an indigenous replication element (cre), into the 5′ non-translated genomic region (with inactivation of the native ere element located in the coding region of 2C (mono-crePV), and replacing the nucleic acid sequence of all or part of the capsid coding region (PI) with a substitute PI coding region having reduced codon pair bias. The stably attenuated poliovirus is effective for vaccines and immunization. | 12-04-2014 |
