Research Abstract |
We have developed replication-competent, attenuated herpes simplex virus-1(HSV-1) mutants, which have been evaluated for their oncolytic activities. However, the host immune system remains a significant obstacle to effective intraperitoneal administration of these viruses in the clinical setting. In this study, we investigated the use of these HSV-1 mutants as oncolytic agents against ovarian cancer and human peritoneal mesothelial cells as carrier cells for intraperitoneal therapy. Our results indicate that these HSV-1 mutants exerts a potent oncolytic effect on ovarian cancer, which may be further enhanced by the utilization of a carrier cell delivery system, based on amplification of viral load and possibly on avoidance of neutralizing antibodies.
