Oncolytic viruses selectively lyse tumor cells, making these agents a promising treatment modality for glioma. Accumulating data suggest that the immune system plays an important role in the anti-glioma activity of oncolytic viruses. In an immune competent glioma model, the therapeutic effect of the oncolytic adenovirus Delta24-RGD was found to depend primarily on antitumor immune responses.
