A possible treatment avenue for influenza?

This recent Washington University School of Medicine press release is intriguing.

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...
"If the macrophages were to die, the infection would spread further," says senior author Michael J. Holtzman, M.D., the Selma and Herman Seldin Professor of Medicine and director of pulmonary and critical care medicine. "So the macrophages use a protein called CCL5 to ensure that the infection process can be stopped before it goes any further."
Holtzman thinks the information about the role of CCL5 may lead to new methods to hasten recovery from respiratory viral inflections like influenza or the common cold, which at present have no pharmacological cure.
