Researchers from Osaka University have found that a brain disorder associated with flu (influenza-associated encephalopathy, or IAE) can be caused by the influenza virus entering the brain from the blood via endothelial cells. In these cells, the researchers observed viral protein accumulation, suggesting that antivirals targeting viral transcription/translation may be useful treatments for some patients. Given the lack of effective treatments for IAE, this finding will likely improve patient care and reduce IAE-related deaths worldwide.
