Minocycline is broadly protective in neurological disease models featuring inflammation and cell death and is being evaluated in clinical trials. Japanese encephalitis virus (JEV) is one of the most important causes of viral encephalitis worldwide. There is no specific treatment for Japanese encephalitis (JE) and no effective antiviral drugs have been discovered. Studies indicate that JE involves profound neuronal loss as well as secondary inflammation caused because of cell death. Minocycline is a semisynthetic second‐generation tetracycline that exerts anti‐inflammatory and antiapoptotic effects that are completely separate from its antimicrobial action. Because tetracycline treatment is clinically well tolerated, we investigated whether minocycline protects against experimental model of JE. Intravenous inoculation of GP78 strain of JEV in adult mice results in lethal encephalitis and caused primarily because of …
