Oncolytic virus simultaneously expressing cd55 and cd59

Abstract

The present invention relates to an oncolytic virus co-expressing the complement regulatory proteins CD55 and CD59. The oncolytic virus of the present invention maintains efficacy even upon intravenous injection, and thus, it may be applied to the therapy for various solid carcinomas and metastatic cancers as well as superficial solid cancers. In addition, the oncolytic virus of the present invention acquires resistance to the attack of human complement system by expressing a complement regulatory protein on the surface of the virus, and thus, it is stable in blood, and it maintains stable oncolytic activity upon intravenous injection, and thus, it may reduce the dose of the virus to minimize adverse effects of anticancer agents. Therefore, the oncolytic virus of the present invention may be advantageously used for prevention or treatment of cancer.
