Lab study: Protein delivered via genetically engineered virus slowed glioblasoma multiforme growth

.... Genetically engineered viruses are used to transport genes and/or proteins into cells and have been used in gene therapy research for the last ten years. Just like a viral infection, they work by tricking cells into accepting them as part of their own genetic coding. To make them safe, scientists rem...
