Transient Transfection-based Fusion Assay for Viral Proteins

[Abstract]  Membrane fusion is vital for entry of enveloped viruses into host cells as well as for direct viral cell-to-cell spread. To understand the fusion mechanism in more detail, we use an infection free system whereby fusion can be induced by a minimal set of the alphaherpesvirus pseudorabies virus (PrV) glycoproteins gB, gH and gL. Here, we describe an optimized protocol of a transient transfection based fusion assay to quantify cell-cell fusion induced by the PrV glycoproteins. [摘要]  膜融合对于将包膜病毒进入宿主细胞以及直接病毒细胞到细胞传播至关重要。为了更好地了解融合机制,我们使用无感染系统,可以通过最小的α疱疹病毒伪狂犬病病毒(PrV)糖蛋白gB,gH和gL诱导融合。在这里,我们描述了基于瞬时转染的融合测定的优化方案,以定量由PrV糖蛋白诱导的细胞 - 细胞融合。

背景 膜融合对于包膜病毒的进入和扩散至关重要。许多包膜病毒只需要一种或两种病毒蛋白来介导宿主细胞的附着和膜融合,分子机制也被很好地理解(Harrison,2015)。相比之下,疱疹病毒使用需要受体结合蛋白的更复杂的机制和由gB和异二聚体gH / gL复合物组成的核心融合机构用于感染性进入。导致疱疹病毒包膜与细胞膜融合的机制尚不完全清楚。疱疹病毒进入和传播的分子基础的详细知识对于针对各种疾病的有效对策是重要的。通过研究瞬时表达相关蛋白质的细胞的细胞融合活性来帮助更好的理解。已经开发了不同的模型系统,其中在不存在感染的情况下,开发了由糖蛋白gB和gH / gL和受体结合gD表示的最小的核心融合机制的融合,例如,对于1型单纯疱疹病毒和2(HSV-1和2 [Turner等人,1998; Muggeridge,2000; ...

[Abstract]  Chronic inflammation drives initiation of hepatocellular carcinoma (HCC), but the underlying mechanisms linking inflammation and tumor formation remain obscure. In this study, Xenograft tumor assay was used to determine the tumorigenic activity of hepatoma cells with ISX over expression on nude mice in vivo.
[摘要]  慢性炎症驱动肝细胞癌(HCC)的引发,但是连接炎症和肿瘤形成的基础机制仍然是模糊的。 在该研究中,使用软琼脂贴壁非依赖性测定来测定具有ISX的肝癌细胞的肿瘤转化活性超过表达或体外敲低。...
