According to the researchers, the findings open up new possibilities for the treatment of nervous system disorders and injuries.and then there's this:
"We are trying to think about human disease in a new way," says collaborator Jeffrey Gimble of Louisiana State University in Baton Rouge. "Everyone is used to the concept of surgical, medical or pharmacological approaches to the treatment of disease—we're looking at one of the next steps in biotechnology, which is using cellular therapies."
Engineered Virus Makes Brain Cells Glow
"By creating viruses unable to follow their normal replication agenda, we can then harness the virus as an important research tool," says Yale researcher Anthony van den Pol. "Viruses with altered genetic codes also have substantial value for the potential treatment of a number of neurological diseases where a gene could be selectively targeted to one defective cell type."
