牛磺胆酸钠共转运多肽(NTCP)是B型肝炎病毒(HBV)进入机体的功能性受体。然而,关于NTCP是否参与调节HBV生命周期的后期步骤知之甚少。在此,我们发现NTCP表达在试验后步骤上调HBV转录,并且NTCP靶向进入抑制剂Myrcludex B(Myr B)在HBV体外感染系统和用HBV表达质粒水动力注射的小鼠中有效抑制HBV转录。从机制上讲,NTCP通过法尼醇X受体α(FxRα)介导的HBV EN 2/核心启动子在试验后步骤的激活上调HBV转录,其方式依赖于NTCP的胆汁酸(BA)转运功能,该功能被MyrB阻断。我们的研究结果揭示了NTCP在HBV生命周期中的新作用,并为使用新型NTCP靶向进入抑制剂来抑制HBV感染和复制提供了参考。
Sodium taurocholate cotransporting polypeptide (NTCP) is a functional receptor for hepatitis B virus (HBV) entry. However, little is known regarding whether NTCP is involved in regulating the postentry steps of the HBV life cycle. Here, we found that NTCP expression upregulated HBV transcription at the postentry step and that the NTCP-targeting entry inhibitor Myrcludex B (MyrB) effectively suppressed HBV transcription both in an HBV in vitro infection system and in mice hydrodynamically injected with an HBV expression plasmid. Mechanistically, NTCP upregulated HBV transcription via farnesoid X receptor α (FxRα)-mediated activation of the HBV EN2/core promoter at the postentry step in a manner that was dependent on the bile acid (BA)-transport function of NTCP, which was blocked by MyrB. Our findings uncover a novel role for NTCP in the HBV life cycle and provide a reference for the use of novel NTCP-targeting entry inhibitors to suppress HBV infection and replication.
