Core Tip
Core Tip: This study uncovers a novel mechanism of hepatitis B virus (HBV) immunity evasion through HBV-miR-3, a recently identified HBV-encoded microRNA. HBV-miR-3 down-regulates the cGAS-STING-IFN pathway by inhibiting cGAS 3’ untranslated region activity, leading to decreased cGAS protein expression, STING phosphorylation, and interferon production. The findings highlight the crucial role of HBV-miR-3 in modulating host immune responses, providing insights into potential therapeutic targets for HBV infection.
