These results suggest that HBV replication can be regulated through interferon-mediated RNA decay pathways and that activation of these host antiviral factors may represent a novel therapeutic strategy for HBV infection. Our data indicate that ligand-mediated activation of these enzymes results in a marked inhibition of HBV replication in both infected and transfected cells. With the newly established HepG2-NTCP cell culture system, which permits HBV infection, we showed that viral gene expression and replication can be profoundly reduced by 2-5Aor poly(I:C)-mediated activation of RNase L. In HBV1.2-transfected Huh-7 cells, it was further confirmed that this type of inhibition occurred mostly through viral RNA degradation via the ribonuclease function of RNase L. ./cache/cord-264488-989t9ld1.txt ./txt/cord-264488-989t9ld1.txt
