Abstract
Hepatitis B virus (HBV) infection poses a global health concern without a definitive cure; however, antiviral medications can effectively suppress viral replication. This study delves into the intricate interplay between lipid metabolism and HBV replication, implicating molecular mechanisms such as the stearoyl coenzyme A desaturase 1 autophagy pathway, SAC1-like phosphatidylinositol phosphatase, and galectin-9 mediated selective autophagy of viral core proteins in regulating HBV replication. Within lipid droplets, perilipin 2 (PLIN2) emerges as a pivotal guardian, with its overexpression protecting against autophagy and downregulation stimulating triglyceride catabolism through the autophagy pathway. This editorial discusses the correlation between hepatic steatosis and HBV replication, emphasizing the role of PLIN2 in this process. The study underscores the multifaceted roles of lipid metabolism, autophagy, and perilipins in HBV replication, shedding light on potential therapeutic avenues.
Core Tip: Hepatitis B virus (HBV) infection poses a global health concern without a definitive cure. This study delves into the complex interplay between lipid metabolism and HBV replication. It reveals that heightened lipid metabolism may exert an inhibitory effect on HBV replication. Specifically, increased fatty acids lead to the accumulation of lipid droplets and the upregulation of perilipin 2 in hepatocytes. This, in turn, inhibits autophagy and subsequently hinders HBV replication.
