abstract：:The covalently closed circular DNA (cccDNA) of hepatitis B virus (HBV) is a viral center molecule for HBV infection and persistence. However, the cellular restriction factors of HBV cccDNA are not well understood. Here, we show that TGF-β can induce nuclear viral cccDNA degradation and hypermutation via activation-ind...
