Comment


Exerts its antiviral activity on a wide range of DNA and RNA viruses including hepatitis C virus (HCV), hepatitis B virus (HBV), measles virus (MV) and herpes simplex virus 1 (HHV-1).PKR activation correlates with enhanced IFN induction, increased mitogen-activated protein (MAP) kinase pathway activation, reduction in virus growth, and increased cytotoxicity and apoptosis of infected cells
