Oncolytic virotherapy has been tested in cancer patients, but its efficacy is uncertain. Alvarez-Breckenridge et al. now report that in mouse models of glioblastoma, an antiviral response mediated by natural killer (NK) cells may impair the anticancer efficacy of oncolytic virotherapy. Their findings suggest that limiting the cytolytic activity of NK cells might enhance replication of oncolytic viruses and increase tumor cell killing.
