ARTICLE HIGHLIGHTS
Research background
The relationship between lipid metabolism and hepatitis B virus (HBV) deoxyribonucleic acid (DNA) replication and its underlying mechanisms are not well understood.
Research motivation
To investigate the relationship between lipid metabolism and HBV DNA replication and its underlying mechanisms.
Research objectives
We speculated that the Plin2-autophagy pathway might be involved in regulating lipid deposition and HBV replication in hepatocytes.
Research methods
We first explored the relationship between patients' lipid levels and HBV DNA load. Also, we constructed an HBV infection combined with a hepatic steatosis cell model in vitro.
Research results
Stratified analysis by HBeAg showed significant negative correlations between HBV-DNA load and hepatic steatosis ratio in both HBeAg-positive group and in HBeAg-negative group. The results of in vitro experiments suggested that fatty acid treatment increased the lipid droplets deposition and decreased the cell supernatant HBsAg, HBeAg expression and HBV DNA load.
