Discovery means targeted solutions can be directed to avian flu viruses sooner to prevent spillover into humans, say scientists
Scientists have discovered that a gene present in humans is preventing most avian flu viruses moving from birds to people. The gene is present in all humans and can be found in the lungs and upper respiratory tract, where flu viruses replicate. It was already known to scientists, but the gene’s antiviral abilities are a new discovery.
A six-year investigative study led by the MRC-University of Glasgow Centre for Virus Research found that the BTN3A3 gene is a powerful barrier against most avian flu viruses.
