New therapies for disorders like Huntington’s disease are on the way, but getting the drugs to enter brain cells can be a major challenge. A group of scientists has redesigned and tested a harmless virus that can efficiently deliver a ‘gene silencing’ message throughout the brain in mice, much further than naturally occurring viruses can reach. What’s more, it can be given with a simple injection into the blood, offering great potential for research in gene silencingresearch and beyond.
