Objective: For quite a long time oncolytic viruses (OVs) have been regarded merely as specific tumor cell killers, while disregarding the fact that all oncolytic activities take place in the context of a functional immune system. Oncolytic parvoviruses (PV) represent non-pathogenic, naturally oncolytic (non-modified), animal (rodent) viruses with a tropism that extends to a number of transformed human cells. Our recent work using various animal models substantiates the contention that H-1PV acts as both an oncolytic agent and an adjuvant, by direct cytoreduction in the tumor and bystander antitumor immunity. ImmunostimulatoryCpG motifs were incorporated into the singlestranded DNA genome of H-1PV and our current objective was to test whether the CpG-armed virus was in possession of an enhanced adjuvant capacity. Methods: The immunogenic potential of the CpG-enriched parvoviral derivat.. View More»
