Discovery of a new feature of a large class of pathogenic viruses, referred to by researchers as a ‘pocket’, may allow development of new antiviral medications for the common cold, polio, and other illnesses, according to a new study published this week in the open-access journal PLOS Biology. Researchers Rana Abdelnabi and Johan Neyts of the University of Leuven, Belgium, and James Geraets and Sarah Butcher of the University of Helsinki and their colleagues note that while it is possible that the newly-discovered pocket may also mutate to make picornaviruses resistant to therapies developed against them, the authors suggest the pocket may be crucial enough for viral replication that viruses containing mutant versions may be less viable. Learn More
