  • Patent number: 11680248
    Abstract: The invention relates to the field of virology and tumor therapy. In particular, the present invention provides a recombinant herpes simplex virus (HSV) capable of specifically replicating at a high level in a tumor cell and effectively killing the tumor cell, but replicating at low levels in normal cells, thereby the recombinant herpes simplex virus of the present invention not only has high lethality against tumor cells, but also has significantly decreased side effects (especially neurotoxicity). Further, the present invention relates to a viral vector constructed based on the recombinant herpes simplex virus, a pharmaceutical composition comprising the recombinant herpes simplex virus or the viral vector, and the use of the recombinant herpes simplex virus or the viral vector. The recombinant herpes simplex virus of the present invention can be used to infect and kill tumor cells, and can be used for gene drug delivery into tumor cells for gene therapy.

  • Patent number: 11642408
    Abstract: An antigen variant and a use thereof are disclosed. The antigen variant is a protein, among surface proteins (gE) of the varicella zoster virus, exhibits a high expression level and high immunogenicity, and thus, when the antigen variant is used as a vaccine composition, the vaccine composition has more excellent safety compared to a live virus vaccine, and the antigen variant exhibits a higher expression level in a host cell compared to other antigens. The antigen variant is useful as a vaccine for preventing or treating chicken pox or herpes zoster caused by the varicella zoster virus.
