英文摘要 | Hepatitis b virus (hbv) is regarded as a stealth virus, invading and replicating efficiently in human liver undetected by host innate antiviral immunity. here, we show that type i interferon (ifn) induction but not its downstream signaling is blocked by hbv replication in hepg2.2.15 cells. this effect may be partially due to hbv x protein (hbx), which impairs ifn beta promoter activation by both sendai virus (sev) and components implicated in signaling by viral sensors. as a deubiquitinating enzyme (dub), hbx cleaves lys63-linked polyubiquitin chains from many proteins except tank-binding kinase 1 (tbk1). it binds and deconjugates retinoic acid-inducible gene i (rig i) and tnf receptor-associated factor 3 (traf3), causing their dissociation from the downstream adaptor cardif or tbk1 kinase. in addition to rig i and traf3, hbx also interacts with cardif, trif, nemo, tbk1, inhibitor of kappa light polypeptide gene enhancer in b-cells, kinase epsilon (ikki) and interferon regulatory factor 3 (irf3). our data indicate that multiple points of signaling pathways can be targeted by hbx to negatively regulate production of type i ifn. |
