    Abstract: The present invention is directed to a method of reducing the viability of a tumor cell involving administering a virus that is not a common human pathogen to the tumor cell. Preferably, the virus exhibits differential susceptibility, in that normal cells are not affected by the virus. This differential susceptibility is more pronounced in the presence of interferon. The tumor cell is characterized by having low levels, or no, PKR activity, or as being PKRnull/null, STAT1null/null or both PKRnull/null and STAT1null/null. The virus is selected from the group consisting of Rhabdovirus and picornavirus, and preferably is vesicular stomatitis virus (VSV) or a derivative thereof.

    Abstract translation: 本发明涉及一种降低肿瘤细胞活力的方法,该方法涉及向肿瘤细胞施用不是常见的人类病原体的病毒。 优选地,病毒表现出差异的易感性,因为正常细胞不受病毒的影响。 这种差异敏感性在干扰素存在下更显着。 肿瘤细胞的特征在于具有低水平或无PKR活性,或PKR - / - ,STAT1 - /或PKR - / - 和STAT1 - / - 两者。 病毒选自Rhabdovirus和小核糖核酸病毒,优选为水泡性口炎病毒(VSV)或其衍生物。
