Researchers from the Russia-based National University of Science and Technology (NUST) MISIS and the University of Calgary say they have learned how to observe the processes of oncolytic viruses in cancer cells in real time. For the first time, the intravital microscopy method was used to study the interaction of oncolytic viruses with both tumor and healthy cells, according to the scientists. The study (“ Visualizing Oncolytic Virus-Host Interactions in Live Mice Using Intravital Microscopy ”) appears in Molecular Therapy Oncolytics .
