It’s not easy to treat viral infections. Just ask anyone with a bad cold or a case of the flu.
But scientists in Massachusetts think they may have a new way to stop viruses from making people sick by using what amounts to a pair of molecular scissors, known as CRISPR.
RNA is a chemical cousin of DNA. Many viruses, including flu and Zika, package their genetic instructions in RNA instead of DNA.
When a virus infects a cell in our bodies, it hijacks the cell’s molecular machinery to make copies of itself.
So for therapy, “we need to be able to cut the virus at a fast enough rate to slow down replication or to stop replication from happening,” says [postdoc] Cameron Myhrvold.
“There’s still a bunch of things we want to work out, but we feel pretty confident that this will work as a therapy if it can be delivered in the right way,” [researcher Pardis] Sabeti says.
