Autophagy (i.e. macroautophagy) plays a significant role in the replication of hepatitis B virus (HBV). In our recent study, we examined the underlying mechanism and discovered that autophagic membranes participated in different steps of the HBV life cycle. We found that phagophores are involved in the assembly of HBV nucleocapsids, autophagosomes participate in the trafficking of HBV nucleocapsids, amphisomes likely participate in the maturation and egress of mature HBV particles, and autolysosomes negatively regulate HBV replication. Our work provides important insights for understanding the relationship between autophagic membranes and HBV replication and raises the possibility of targeting the autophagic pathway for the development of novel drugs against HBV.
