Studying West Nile virus infection in mice, scientists at Washington University School of
Medicine in St. Louis showed that interferon-lambda tightens the blood-brain barrier, making it harder for the virus to invade the brain.
The blood-brain barrier is a natural defense system that is supposed
to keep pathogens out of the brain. Sometimes, however, bacteria or
viruses circulating in the blood slip past the blood-brain barrier,
turning routine illnesses into serious infections.
