Patents by Inventor Zhen Fang Fu

Zhen Fang Fu has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7544791
    Abstract: A mutant virus is provided which contains a mutation at a phosphorylation site in one or more of the proteins of the virus, which mutation causes the virus to be attenuated, and therefore, an improved vaccine composition can be produced therewith. The invention also relates to vaccine compositions which contain the mutant virus, as well as to methods of inducing an immune response, and of protecting mammals from infection by rabies virus. Also included in the invention are methods of producing the mutant virus and mutant viral proteins, including producing the mutant virus in a host cell which produces or even overproduces a wild-type counterpart of the mutant viral protein, which complements the other viral proteins such that production of the mutant viral particle is optimized.
    Type: Grant

  • Patent number: 7419816
    Abstract: A mutant virus contains a mutation at a phosphorylation site in one or more viral proteins, which attenuates the virus, and an improved vaccine composition. The invention also relates to methods of inducing an immune response, and protecting mammals from infection by rabies virus. Also included are methods of producing the mutant virus and mutant viral proteins, including producing the mutant virus in a host cell which produces or-overproduces a wild-type counterpart of the mutant viral protein, which complements the other viral proteins such that production of the mutant viral particle is optimized. The invention also includes those host cells, vaccine compositions including the viral proteins,-alone or in combination with-intact virus, and methods of inducing an immune response or protecting a mammal from infection. Also included are vectors suitable for delivering a gene to a cell of a human or animal, and methods of delivery thereof.

  • Patent number: 6355621
    Abstract: Oligodeoxynucleotides complementary to genomic RNA of a negative-stranded nonsegmented RNA virus are provided. Methods of inhibiting infection of cells by a negative-stranded nonsegmented RNA virus and treating animals infected with a negative-stranded nonsegmented RNA virus using these oligodeoxynucleotides are also provided.

  • Patent number: 5935570
    Abstract: A process for the synthesis and delivery of bioactive compounds, compounds that have a therapeutic, biochemical, or immunologic, effect on an animal, such as human. In the process, clavibacter is genetically altered so that it synthesizes the bioactive compound. A plant may be infected with the genetically altered clavibacter and used an as oral delivery system.
