Abstract:
This invention relates to improved methods for producing nonsegmented, negative-sense, single-stranded RNA viruses of the Order designated Mononegavirales virus, including embodiments relating to methods of producing such viruses as attenuated and/or infectious viruses, such as Measles virus (MV) and respiratory syncytial virus (RSV). One method for producing a recombinant virus from the Order Mononegavirales comprises (a) in at least one host cell, conducting transfection of a rescue composition which comprises (i) a transcription vector comprising an isolated nucleic acid molecule which comprises polynucleotide sequence encoding a genome or antigenome of a nonsegmented, negative-sense, single stranded RNA virus of the Order Mononegavirales and (ii) at least one expression vector which comprises at least one isolated nucleic acid molecule encoding the trans-acting proteins necessary for encapsidation, transcription and replication; in a host cell under conditions sufficient to permit the co-expression of these vectors and the production of the recombinant virus; (b) heating the transfected rescue composition to an effective heat shock temperature under conditions sufficient to increase the recovery of the recombinant virus; and optionally, (c) harvesting the resulting recombinant virus.

Abstract:
A method of inducing an antigen-specific immune response in a mammalian subject includes the steps of administering to the subject an effective amount of a first composition comprising a DNA plasmid comprising a DNA sequence encoding an antigen under the control of regulatory sequences directing expression thereof in a mammalian or vertebrate cell. The method also includes administering to the subject an effective amount of a second composition comprising a recombinant vesicular stomatitis virus (rVSV) comprising a nucleic acid sequence encoding the antigen under the control of regulatory sequences directing expression thereof in the mammalian or vertebrate cell. The rVSV is in one embodiment replication competent. Kits for use in immunizations and therapeutic treatments of disease include the components and instructions for practice of this method.

Fusogenic, Self-Propagating Blebs As Immunogenic Compositions

Fusogenic, Self-Propagating Blebs As Immunogenic Compositions

US Patent:
7541038, Jun 2, 2009
Filed:
Jun 2, 2004
Appl. No.:
10/559429
Inventors:
Gerald Raul Kovacs - Potomac MD, US
Xiaoyan Mo - Boxborough MA, US
Nikolaos Vasilakis - Galveston TX, US
Sangeeta Bhargava - Potomac MD, US
Timothy Joseph Zamb - Nyack NY, US
Stephen Alexander Udem - New York NY, US
Assignee:
Wyeth Holdings Corporation - Madison NJ
International Classification:
A61K 39/155, C12N 15/86
US Classification:
4241991, 4242111, 4353201, 4352351
Abstract:
Self-propagating, fusogenic blebs are produced from cells infected with a population of Venezuelan Equine Encephalitis virus replicon particles (VRP). The self-propagating, fusogenic nature of the blebs is derived from expression of heterologous genes encoding viral fusion proteins that are incorporated into the replication defective replicon particles. The resulting blebs can be harvested from supernatants of cells displaying severe cytopathic effects. The blebs are used to make immunogenic compositions and devise methods of immunizing mammals against paramyxoviruses such as parainfluenza virus type 3.
