Recombinant VSVs: A Promising Tool for Virotherapy.

Cancer is one of the leading causes of death worldwide. Traditional cancer treatments include surgery, radiotherapy, and chemotherapy, as well as combinations of these treatments. Despite significant advances in these fields, the search for innovative ways to treat malignant tumors, including the application of oncolytic viruses, remains relevant. One such virus is the vesicular stomatitis virus (VSV), which possess a number of useful oncolytic properties. However, VSV-based drugs are still in their infancy and are yet to be approved for clinical use. This review discusses the mechanisms of oncogenesis, the antiviral response of tumor and normal cells, and markers of tumor cell resistance to VSV virotherapy. In addition, it examines methods for producing and arming recombinant VSV and provides examples of clinical trials. The data presented will allow better assessment of the prospects of using VSV as an oncolytic.
