ABSTRACT
High-mobility group box-1 (HMGB1) is a member of the high-mobility group proteins and is present in eukaryotic cells. HMGB1 is not only a nuclear protein but also a pro-inflammatory factor, and the increase in HMGB1 level in the body indicates cell destruction and inflammatory response. Hepatitis B virus (HBV) infection is a major cause of chronic hepatitis B, liver cirrhosis, and hepatocellular carcinoma in the world. In recent years, the role of HMGB1 in HBV-related liver diseases has attracted more and more attention, especially the important role of HMGB1 in the progression of liver inflammation and liver cancer. This article reviews the recent research advances in the role of HMGB1 in the development, progression, and treatment of HBV-related liver diseases.
