This discovery, like most, raises at least as many questions as it answers. “It’s a beautiful piece of science,” says Ann C. Palmenberg, a University of Wisconsin, Madison biochemist and enterovirus expert who was not involved with the research. But “don’t throw away your chicken soup just yet,” she says. Until Carette’s team is able to figure out how and why this specific protein is so important to enterovirus replication, she says there’s no way to know what treatments it may or may not lead to. “Getting from where they are to where they would like to be is another 20 years of work,” she says.
