人类乙型肝炎病毒(HBV)感染仍然是全世界严重的健康问题。然而,HBV 在宿主细胞内维持潜伏状态的机制仍不清楚。在这里,利用单细胞 RNA 测序分析,我们在低频率表达 HBV RNA 的肝细胞系中鉴定了与 HBV 维持相关的四个基因。这些基因包括 DOCK11 和 DENND2A,它们编码小型 GTP 酶调节因子。在感染 HBV 的原代人肝细胞中,敲低这两个基因可将 HBV DNA 和共价闭合环状 DNA 的量降低至检测限以下。我们的研究结果揭示了 DOCK11 和 DENND2A 在维持 HBV 中的作用。
Human hepatitis B virus (HBV) infection remains a serious health problem worldwide. However, the mechanism for the maintenance of HBV in a latent state within host cells remains unclear. Here, using single-cell RNA sequencing analysis, we identified four genes linked to the maintenance of HBV in a liver cell line expressing HBV RNA at a low frequency. These genes included DOCK11 and DENND2A, which encode small GTPase regulators. In primary human hepatocytes infected with HBV, knockdown of these two genes decreased the amount of both HBV DNA and covalently closed circular DNA to below the limit of detection. Our findings reveal a role for DOCK11 and DENND2A in the maintenance of HBV.
