A natural lipid in the fluid lining the lungs inhibits influenza infections in both cell cultures and mouse models, according to researchers at National Jewish Health. These findings, combined with previous studies demonstrating effectiveness against respiratory syncytial virus, suggest that the molecule, known as POPG, may have broad antiviral activity. “Supplemental POPG could be an important, inexpensive and novel approach for the prevention and treatment of influenza and other respiratory virus infections,” said Dennis Voelker, PhD, Professor of Medicine, and senior author in the report, published online in the American journal of Respiratory Cell and Molecular Biology.

Researchers at National Jewish Health have discovered that a naturally occurring lipid in the lung can prevent RSV infection and inhibit spread of the virus after an infection is established. RSV is the major cause of hospitalization for children in the first two years of life, and is increasingly recognized as a dangerous pathogen in adults with chronic lung diseases, the elderly, and immunocompromised individuals. Currently, there is no effective vaccine for the virus. The findings, published in the December 21, 2009, issue of The Proceedings of the National Academy of Sciences, also help explain how the lipid, known as...
