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.
