This preclinical study investigated the therapeutic efficacy of electroporation (EP)-based delivery of plasmid DNA (pDNA) encoding viral proteins (envelope, core) and IFN-γ in the duck model of chronic hepatitis B virus (DHBV) infection. Importantly, only DNA EP-therapy resulted in a significant decrease in mean viremia titers and in intrahepatic covalently(More)

Chronic hepatitis B virus infection is a leading cause of cirrhosis and liver cancer. Hepatitis B virus encodes the regulatory HBx protein whose primary role is to promote transcription of the viral genome, which persists as an extrachromosomal DNA circle in infected cells. HBx accomplishes this task by an unusual mechanism, enhancing transcription only(More)
Cationic cell-penetrating peptides (CPPs) and their lipid domain-conjugates (CatLip) are agents for the delivery of (uncharged) biologically active molecules into the cell. Using infection and transfection assays we surprisingly discovered that CatLip peptides were able to inhibit replication of Duck Hepatitis B Virus (DHBV), a reference model for human(More)
We explored in the duck hepatitis B virus (DHBV) model the impact of duck interferon gamma (Du-IFNgamma) or interleukin 2 (Du-IL2) co-delivery on humoral neutralizing response induced by DNA-based vaccine encoding DHBV preS/S large envelope protein. Co-delivery of either Du-IL2 or Du-IFNgamma encoding plasmids considerably increased the magnitude of(More)
