Explainer: oncolytic viruses

A recent publication from Bill Kaiser’s and Ed Mocarski’s labs in Cell Host & Microbe touches on a concept that needs explaining: oncolytic viruses.

Viruses have been subverting the machinery of healthy cells for millions of years, and many viruses tend to infect particular tissues or cell types. So they are a natural starting point for researchers to engineer oncolytic viruses, which preferentially infect and kill cancer cells.

Several oncolytic viruses have progressed to advanced clinical trials. Amgen’s “T-Vec”, a modified herpes simplex virus, could be the first to be approved by the FDA this year based on its efficacy against metastatic melanoma.  Read more
