The Wnt/β-catenin pathway is important for replication of SARS-CoV-2 and other pathogenic RNA viruses.

Summary: When a virus like the one that causes COVID-19 gets inside us, it tricks our cells. It turns on a special switch called the Wnt pathway. This switch turns off our cell's tiny virus-fighting factories, called peroxisomes. Because of this, our bodies can't make enough of the alarm signals needed to fight the virus. Scientists found that if they use medicine to block this switch, the factories turn back on. The body makes more alarm signals, and the virus stops copying itself. This worked in sick mice and could be a great new way to treat COVID-19 and other viruses in the future!
