研究人员为了追踪核心蛋白和 LHBs 蛋白在细胞内的路径,确定它们在哪个细胞区室相遇并促进 HBV 病毒颗粒的形成,开展了一系列实验。他们主要运用了以下几种关键技术方法:一是利用荧光共振能量转移(FRET)和荧光寿命成像显微镜(FLIM)技术,可视化两种蛋白的相互作用;二是借助透射电子显微镜(TEM)和免疫 TEM ...
cccDNA 指导病毒 RNA 的转录,其中 3.5kb 的 RNA 编码核心蛋白和病毒 DNA 聚合酶,同时作为合成 HBV 基因组 DNA 的模板,被称为前基因组 RNA(pgRNA)。pgRNA 在核心颗粒中经病毒 DNA 聚合酶(也是逆转录酶)作用,先逆转录为负链 DNA,再合成正链,形成松弛环状 DNA(rcDNA ...
rcDNA 经宿主滞后链合成机制修复为完全双链的共价闭合环形 DNA(cccDNA),人体细胞中的组蛋白迅速沉积于 cccDNA 形成微型染色体,作为 HBV 病毒转录 ...
At least one-third of the world's population has been infected with the hepatitis B virus (HBV), and 400 million people are chronic carriers. In most populations, chronic HBV infection is the ...
Despite numerous treatment advances, chronic hepatitis B virus (HBV) infection remains a largely incurable disease impacting more than 290 million people worldwide. All patients with chronic HBV ...
Precision BioSciences has reported initial outcomes from the ELIMINATE-B trial of PBGENE-HBV, a gene editing programme for treating chronic Hepatitis B patients who are HBeAg-negative. In cohort ...
