NYU Study Reveals How Brain's Immune System Fights Viral Encephalitis

...s fights viral infection of neurons. The findings, published as the cover study in the latest issue of Virology, show that proteins in neurons fight the virus at multiple stages--by preventing the formation of viral RNA and proteins, and blocking the virus' release, which could infect other cells in the brain....
