摘要:
记者问:丁型肝炎病毒特点是什么?任锋教授:丁型肝炎(丁肝)是由丁型肝炎病毒(HDV)感染引起的一种病毒性肝炎。HDV是一种缺陷病毒,利用乙型肝炎病毒表面抗原(HBsAg)进入肝细胞。因此,HDV可与HBV联合或重叠感染。与单独慢乙肝患者相比,HDV/HBV重叠感染的肝脏疾病更为严重并且进展更快,约90%会进展为慢性肝炎,发生肝衰竭、肝硬化和肝癌等不良结局风险显著增加。

摘要:
目的 构建一种可以实现丁型肝炎病毒(HDV)复制包装的HDV转座子载体.方法 采用分子克隆方法构建含HDV复制子和乙型肝炎病毒表面抗原(HBsAg)表达框的转座子(PB)载体PB126I3,将构建好的载体转染HuH-7细胞,转染48 h后用荧光显微镜观察绿色荧光蛋白(GFP)的表达,转染48 h后收集细胞上清用酶联免疫吸附法(ELISA)检测HBsAg的表达,质粒转染细胞8.5 d后提取病毒用逆转录荧光定量聚合酶链反应(RT-qPCR)检测HDV核糖核酸(RNA)的含量;同时细胞上清病毒浓缩后感染HBV受体钠离子/牛磺胆酸共转运蛋白(Na+/NTCP)稳定转染的HepG2.N9细胞系并于感染后第7天用免疫荧光检测细胞内HDVδ抗原的表达.结果 HDV复制包装载体PB126I3瞬时转染HuH-7后细胞上清可检测到HBsAg的表达和较高滴度的HDV颗粒,并且该病毒颗粒感染HepG2.N9细胞7 d后细胞内可检测到HDVδ抗原.结论HDV复制包装转座子载体构建成功,为未来HDV的大规模复制包装以及尝试建立HDV稳定转染细胞系提供前期基础.%Objective To construct a transposon vector for hepatitis D virus (HDV) replication and packaging. Methods The piggyBac (PB) transposon vector PB126I3 containing HDV replicon and hepatitis B virus surface antigen (HBsAg) expression cassette was constructed by using standard molecular cloning methods. HuH-7 cells were transfected with the vector PB126I3. The expression of green fluorescent protein (GFP) was observed by fluorescence microscopy, and the HBsAg expression level in cell medium was detected by ELISA 48 hours after transfection. HDV RNA in cell supernatants was extracted and detected by reverse transcription-quantitative polymerase chain reaction (RT-qPCR) 8.5 days after transfection. Meanwhile, HDV particles in cell medium were concentrated and infected the HepG2.N9 cells which were stably transfected with HBV receptor NTCP. The cellular expression of HDV δ antigen was detected by immunofluorescence 7 days after infection. Results HuH-7 cells were successfully transfected by the vector PB126I3, and secreted a large number of HBsAg and HDV particles in cell medium. HDV δ antigen was detected obviously in HepG2.N9 cells 7 days after HDV infection. Conclusions HDV replicon vector PB126I3 were successfully constructed for HDV replication and packaging, which will promote the large-scale of HDV production and HDV transgenic hepatocyte cell line establishment in the future.

摘要:
丁型肝炎病毒(HDV)是乙型肝炎病毒(HBV)的卫星病毒,呈世界性流行,其感染和复制与HBV感染存在密不可分的联系.我国是HBV感染的高发国家之一,HBV相关研究较多,但对其卫星病毒HDV的研究较少.我们较全面地梳理了HDV的分子生物学特征、流行病学特点、实验研究模型、检测、预防及治疗几个方面的最新进展,期望对未来HDV的研究起到一定的推动作用.%Hepatitis D virus(HDV),the satellite of hepatitis B virus(HBV),is a worldwide human pathogen.The infection and replication of HDV are inseparable with HBV.China is one of the countries with high incidence of HBV infection,and many research projects focus on HBV but few on its satellite virus HDV.In this review,the latest developments in HDV molecular biology,epidemiological characteristics,experimental models,detection,prevention and treatment were introduced and summarized comprehensively.We hope this paper can play a certain role in the future study of HDV.

摘要:
The present paper aims to clone and analyze the sequence of full‐length cDNA of hepatitis D virus (HDV) in China .HDV RNA was extracted from three HDV seropositive samples .cDNA was obtained by reverse transcription‐polymerase chain reaction (RT‐PCR) .Four overlapped fragments were amplified by nested PCR ,and the products were sequenced .The full‐length sequences were joined by DNAStar .The full‐length cDNA of HDV was amplified by overlapping PCR using designed primers and connected to the cloning T vector . Three strains of HDV were successfully amplified and cloned . The three HDV strains were all genotype Ib .The nucleic acid sequence homology of the three HDV strains was over 98% .They had over 98% sequence homology to genotype I Chinese strain X77627 ,and >84% sequence homology to other genotype I strains . They had no more than 77% and 66% sequence homology to genotype II and genotype III respectively .In conclusion ,we cloned full‐length cDNA of three strains of HDV ,which could be helpful for the further study of HDV molecular biology .%为构建我国丁型肝炎病毒(HDV)全基因克隆,分别从3份 HDV阳性血清中提取病毒 RNA ,通过反转录‐聚合酶链反应(RT‐PCR)分段扩增,获得4个相互重叠的DNA片段,将PCR产物测序,利用DNAStar软件拼接,获得HDV全基因组序列;设计引物,用重叠PCR扩增全长 HDV片段并连接至克隆载体,构建全基因克隆。结果成功克隆出3株1675 bp的HDV全长基因组。经与GenBank标准序列比对,3株HDV均为基因Ⅰb型,核酸序列同源性达98%以上,与我国Ⅰ型X77627的同源性均达98%以上,与其他基因Ⅰ型的同源性均高于84%。与基因Ⅱ型和Ⅲ型的同源性分别低于77%和66%。本研究构建了3株具有我国代表性的HDV全长基因cDNA克隆,为进一步开展HDV分子生物学研究提供了基础。
