最近,童舒平、张继明和夏宁邵团队在《Gut》发表”Naturally occurring 5′preS1 deletions markedly enhance replication and infectivity of HBV genotype B and genotype C”,发现慢乙肝患者来源的HBV病毒前S1蛋白具有缺失突变,缺失突变可...
The initial entry step in HBV infection involves interaction between the pre-S1 domain of the large hepatitis B surface protein (LHBsAg) and the sodium taurocholate cotransporting polypeptide (NTCP), which is a receptor for HBV. In this study, ergosterol peroxide (EP) was identified as a new ...
The expression of some of these cytokines (that is, constitu- tively lower levels of pro-inflammatory cytokines IL-6, IL-8 and TNF-a, and the chemokines CCL3 and CCL4) was validated at the protein level in the supernatant of ex vivo-sorted monocytes (Supplementary Fig. 5). Direct ex ...

由于NP在不同类型HV中较为保守,因此可诱导各表达系统产生针对PUUV、DOBV和ANDV NP的高度交叉应答。与仅表达Gc或Gn的亚单位疫苗相比,Gc/Gn联合使用或与NP联合免疫可诱导更高滴度抗体应答,提供抗体种类更全面、中和抗体滴度更高的完全保护,仅表达NP的杆状病毒重组蛋白也可以保护实验动物免受HV感染攻击。此外,佐剂可...

在高HBV慢性携带者的流行区域,从感染的母亲传染给新生儿的垂直传播是最常见的污染模式并且几乎总是造成慢性肝炎(90%的病例)。通过出生后立即对感染的婴儿进行预防性接种,该比率可被降低至15%。在西方国家,感染最有可能通过水平传播发生于成年期,其通过体液如血液、精液、唾液,在85%的患者中造成急性和自我恢复感染,...

The cells further process the chimeric HBV-human protein and then present HBV epitopes through MHC molecules for T cell to recognize (Gehring et al., 2011; Tan et al., 2019). However, analysis of the antigen-specificities of tumor-infiltrating T cells is usually limited due to the lack of...
rcccDNA-mediated HBV replication in Huh7 cells. In the natural HBV life cycle, the cccDNA serves as the transcriptional template for synthesizing viral RNAs; among them, the pre-genomic RNA (pgRNA) is encapsidated by the viral core protein to form the capsid and subsequently served as a...
