  • Patent number: 8133481
    Abstract: The present invention provides recombinant viruses which replicate the viral genome selectively in response to the intracellular conditions of the target cell through the use a pathway-responsive promoter which substantially inhibits viral replication in the host cell based on the phenotypic or genotypic of the infected cell. In the target cell, the promoter element of the pathway-responsive promoter is inactive and thus the virus is permitted to replicate. This results in: (1) killing the cells by natural lytic nature of the virus, and/or (2) provides a therapeutic dose of a transgene product (amplified in comparison to replication incompetent vectors) to the target cell, and (3) producing a localized concentration of the virus facilitating the infection of surrounding cells to the recombinant virus.

  • Patent number: 5994134
    Abstract: The present invention is directed to a method of producing recombinant viral vectors at high titers incorporating a variety of important advancements over the art. The method of the present invention incorporates multiple features which provide enhanced production of viruses, particularly those viruses encoding exogenous transgenes. The specifically illustrated method describes a method for the high titer serum-free media production of recombinant replication defective adenoviruses containing an exogenous transgene. The invention provides methods of preparing microcarriers, methods for seeding bioreactors at high cell density, increasing the infectivity of the producer cells to the virus, methods to increase product yield through synchronization of the cell cycle of the producer cells, and methods to minimize the deleterious effects of exogenous transgenes. The invention further provides producer cells prepared by the process of the invention. The invention further provides viruses produced by the process.
