RESUMO
Hepatotropism is a prominent feature of hepatitis B virus (HBV) infection. Cell lines of nonhepatic origin do not independently support HBV replication. Here, we show that the nuclear hormone receptors, hepatocyte nuclear factor 4 and retinoid X receptor α plus peroxisome proliferator-activated receptor α, support HBV replication in nonhepatic cells by controlling pregenomic RNA synthesis, indicating these liver-enriched transcription factors control a unique molecular switch restricting viral tropism. In contrast, hepatocyte nuclear factor 3 antagonizes nuclear hormone receptor-mediated viral replication, demonstrating distinct regulatory roles for these liver-enriched transcription factors.
