丙型肝炎病毒(HCV)是一种持续性感染,并导致慢性肝炎。慢性肝炎患者常发展为肝硬化并发展为肝癌。这种病理状态的发展与病毒的持续感染有关。换句话说,病毒复制/增殖可能有助于疾病病理学。越来越多的临床研究表明,HCV感染改变脂质代谢,从而导致脂肪肝。据报道,这种异常代谢会加重肝脏疾病。最近,我们发现脂滴在HCV复制中起关键作用。了解HCV复制的分子机制将有助于阐明其致病机制,并制定预防措施,通过阻断持续感染来抑制疾病的表现。在这篇综述中,我们概述了最近的研究结果,在HCV复制周期的脂滴的功能,并描述肝脏疾病的发展和病毒复制之间的关系。
Hepatitis C virus (HCV) establishes a persistent infection and causes chronic hepatitis. Chronic hepatitis patients often develop hepatic cirrhosis and progress to liver cancer. The development of this pathological condition is linked to the persistent infection of the virus. In other words, viral replication/multiplication may contribute to disease pathology. Accumulating clinical studies suggest that HCV infection alters lipid metabolism, and thus causes fatty liver. It has been reported that this abnormal metabolism exacerbates hepatic diseases. Recently, we revealed that lipid droplets play a key role in HCV replication. Understanding the molecular mechanism of HCV replication will help elucidate the pathogenic mechanism and develop preventive measures that inhibit disease manifestation by blocking persistent infection. In this review, we outline recent findings on the function of lipid droplets in the HCV replication cycle and describe the relationship between the development of liver diseases and virus replication.
