Hepatitis C virus (HCV) modulates cellular lipid metabolism to enhance its replication. HCV circulates in the blood in association with lipoproteins. HCV infection is associated with enhanced lipogenesis, reduced secretion and β-oxidation of lipids. HCV-induced imbalance in lipid homeostasis leads to steatosis. Many lipids are crucial for viral life cycle, and inhibitors of cholesterol/fatty acid biosynthetic pathways inhibit viral replication, maturation and secretion. HCV negatively modulates the synthesis and secretion of very low-density lipoproteins (VLDL). The components involved in VLDL assembly are also required for HCV morphogenesis/secretion, suggesting that HCV coopts the VLDL secretory pathway for its own secretion. This review highlights HCV-altered lipid metabolic events that aid in the viral life cycle and ultimately promote liver disease pathogenesis.
