Core Tip

Core Tip: Our data suggest that fatty acid stimulation inhibits hepatitis B virus (HBV) replication by upregulating Plin2 expression, inhibiting hepatocyte autophagy. This process associates with lipid metabolism, autophagy pathway, and HBV replication. Further study of lipid metabolism-Plin2-autophagy is important to understand HBV host interactions and pathogenesis better and suggests a possible route for treating patients with chronic HBV infection combined with nonalcoholic fatty liver disease.
