Abstract: Proposed are a recombinant herpes simplex virus for multiple targeting and the use thereof. Particularly, a recombinant HSV capable of multiple targeting through multiple expression of an adapter, which is a fused protein of a cancer-cell-targeting domain and an extracellular domain of HVEM, a recombinant HSV capable of multiple targeting by having a modified glycoprotein so as to enable retargeting, in addition to being capable of expressing the adapter that is the fused protein of the cancer-cell-targeting domain and the extracellular domain of HVEM, and the use of the virus for anti-inflammatory therapy are disclosed.
Abstract: Proposed are a recombinant herpes simplex virus having a modified glycoprotein gH for retargeting and the use thereof. Particularly, the recombinant herpes simplex virus is capable of infecting a target cell having a target molecule to which a cell-targeting domain specifically recognizes and binds due to the presence of the cell-targeting domain in the glycoprotein gH thereof, and is thus useful for anticancer therapy or gene therapy.
Abstract: The present invention relates to a recombinant herpes simplex virus (HSV) containing an expression cassette capable of expressing a fused protein of a cancer-cell-targeting domain and an extracellular domain of HVEM and the use thereof. When the recombinant HSV infects and enters target cells, which are cancer cells, HSV proliferates, and an adapter, which is the fused protein, is expressed in the cells and is released to the outside of the cells along with the proliferated HSV virion upon cell lysis, or is released even before the virion is released due to cell lysis when the adapter contains a leader sequence, and the fused protein released to the outside of the cells acts to induce the HSV virion to infect surrounding cancer cells expressing a target molecule recognized by the cancer-cell-targeting domain or to increase the infection efficiency thereof.
