HBV cccDNA: viral persistence reservoir and key obstacle for a cure of chronic hepatitis B
5 Jun 2015
Abstract excerpt
At least 250 million people worldwide are chronically infected with HBV, a small hepatotropic DNA virus that replicates through reverse transcription. Chronic infection greatly increases the risk for terminal liver disease.
