Hepatitis B Virus (HBV) infection is one of the main causes of liver diseases, affecting approximately 292 million people worldwide who are chronic carriers of HBV, leading to severe conditions like liver cirrhosis and primary liver cancer. The infection process of HBV relies on the binding of the viral envelope proteins to receptors on the cell surface. Therefore, interfering with the binding of the viral envelope proteins and receptors can be an effective antiviral strategy. During the 15th Chronic Viral Hepatitis Antiviral Treatment Challenges and Hot Topics Academic Conference, held in Chongqing from November 17-19, 2023, and organized by the Chinese Medical Journal Company Ltd., Editorial Office of the Chinese Journal of Hepatology, and co-organized by the Hepatitis Group of the Chinese Society of Hepatology, the Second Affiliated Hospital of Chongqing Medical University, and the Chongqing Medical University Institute of Viral Hepatitis, Dr. Ailong Huang, President of Chongqing Medical University, shared his team's latest research findings on how HBV depends on various receptors and auxiliary receptors to infect cells. This research provides new insights into the mechanism of HBV invasion and the development of novel drugs to block HBV infection.
