Cellular RNA as a Key Modulator of Mitochondrial Antiviral Signaling

Scientists have uncovered a new role for a cell's own RNA in fending off attacks by RNA viruses. Some of the cell's RNA molecules, researchers found, help regulate antiviral signaling. These signals are part of the intricate coordination of immune responses against virus invasion.
