Chronic infection with hepatitis B virus (HBV) often leads to the development of liver cancer and cirrhosis, creating immense sociological, clinical and economic burdens worldwide. Although current anti-HBV medications manage to control the disease progression and help restore normal liver functions, they often fail to eliminate the virus completely. A major reason for this failure is the presence of a stable viral genome in the hepatocyte nucleus: the covalently closed circular DNA (cccDNA). Targeting HBV cccDNA is a promising approach that could lead to a complete cure. Here, we review various research approaches that are directed toward eliminating HBV cccDNA. This is a brief, yet comprehensive, summary of current state-of-the-art developments in this emerging area of interest.
慢性乙型肝炎病毒 (HBV) 感染常导致肝癌和肝硬化的发生,给全球带来了巨大的社会、临床和经济负担。虽然目前的抗 HBV 药物能够控制疾病进展并帮助恢复正常的肝功能,但它们往往无法完全清除病毒。这种失败的一个主要原因是肝细胞核中存在稳定的病毒基因组:共价闭合环状 DNA (cccDNA)。针对 HBV cccDNA 是一种很有前途的方法,可以实现完全治愈。在这里,我们综述了各种旨在消除 HBV cccDNA 的研究方法。这是对该新兴研究领域当前最新进展的简要而全面的总结。
