Image: This photomicrograph depicts airway epithelial cells from lung tissue of a COPD patient. The cell nuclei have been stained to reveal IL-33, a type of signaling molecule found at high levels in COPD patients. New research shows that viral infection can induce these cells to proliferate. Release of IL-33 from these cells promotes inflammatory mucus production. These findings provide insight into the mechanisms linking acute infection to chronic inflammatory lung disease (Photo courtesy of Holtzman Lab, Washington University School of Medicine).

Cytokines Induced by Exposure to Airborne Pollutants Drive the Transition from Acute to Chronic Lung Infections

Molecular signaling molecules that link acute viral infections with the development of chronic diseases such as chronic obstructive pulmonary disease have been identified in a mouse model and in human patient samples. More...
