Shorter colds, milder flu may follow from newly revealed immune mechanism: "Enlisted to help fight viral infections, immune cells called macrophages consume virus-infected cells to stop the spread of the disease in the body. Now researchers at Washington University School of Medicine in St. Louis have uncovered how macrophages keep from succumbing to the infection themselves. Boosting this mechanism may be a way to speed recovery from respiratory infections."
