| Outline of Final Research Achievements |
It is not well understood how hepatitis B virus (HBV) evades DNA sensor-mediated IFN signaling pathways. In this study, we have shown that HBV polymerase inhibits STING (stimulator of interferon genes)-mediated IFN signaling pathways. Furthermore, the interaction between HBV polymerase and STING was observed. These results provide an additional molecular mechanism how HBV counteracts the innate immunity and may pave the way for the development of new antiviral therapy.
