Chun-Yu Chen, Pin-Yi Wang, Timothy P. Cripe

Abstract

This disclosure relates to a modified oncolytic herpes simplex virus (oHSV) comprising an expression cassette encoding a histidine-rich glycoprotein (HRG), and uses thereof. One promising avenue for the treatment of cancer is oncolytic virotherapy, e.g., oncolytic Herpes Simplex Virus (oHSV) which utilizes genetically modified viruses to selectively target and lyse cancer cells while sparing the normal cells. Oncolytic virotherapy is a safe and effective immunotherapeutic platform for different types of cancers.
