[Abstract]  Many postitive-stranded RNA viruses, such as Hepatitis C virus (HCV), highjack cellular membranes, including the Golgi, ER, mitchondria, lipid droplets, and utilize them for replication of their RNA genome or assembly of new virions. By investigating how viral proteins associate with cellular membranes we will better understand the roles of cellular membranes in the viral life cycle. Our lab has focused specifically on the role of lipid droplets and lipid-rich membranes in the life cycle of HCV. To analyze the role of lipid-rich membranes in HCV RNA replication, we utilized a membrane ... [摘要]  许多假性绞线的RNA病毒,例如丙型肝炎病毒(HCV),高压细胞膜,包括高尔基体,ER,马钱子树,脂滴,并利用它们复制其RNA基因组或组装新的病毒粒子。通过调查病毒蛋白如何与细胞膜结合,我们将更好地了解细胞膜在病毒生命周期中的作用。我们的实验室特别关注脂质滴和富含脂质的膜在HCV的生命周期中的作用。为了分析富含脂质的膜在HCV RNA复制中的作用,我们使用基于由Yeaman等人(2001)开发的10-20-30%碘克沙醇密度梯度的膜浮选测定。该梯度导致在梯度的几乎整个长度上密度的线性增加,并且膜颗粒基于其浮力特性在梯度中分离。为了保存裂解物中的膜,在缺乏洗涤剂的缓冲液中机械破碎细胞。将细胞裂解物加载在梯度的底部,用梯度覆盖,并且膜随着碘克沙醇梯度自我产生而浮起。膜的脂质含量和相关蛋白的浓度将决定梯度内不同膜的分离。离心后,可以从梯度的顶部取样级分,并使用标准SDS-PAGE和蛋白质印迹分析来分析感兴趣的蛋白质。

[Abstract]  Investigations of the activation processes involved in human monocytes and monocyte-derived macrophages and dendritic cells often required large numbers of cells that have not been possibly altered or activated by adherence to surfaces, by binding of antibodies to surface antigens during positive selection, or by release of activators by platelets or other non myeloid cells during isolation or co-culture. Human peripheral blood monocytes as well as lymphocytes from the same blood donor can be isolated by counterflow elutriation using a modification of the technique of Lionetti et al. ... [摘要]  涉及人单核细胞和单核细胞衍生的巨噬细胞和树突细胞的激活过程的研究通常需要大量的细胞,这些细胞不可能通过附着于表面而改变或活化,通过在阳性选择期间抗体与表面抗原的结合,或通过释放 的血小板或其他非骨髓细胞在分离或共培养期间的活化剂。 人类外周血单核细胞以及来自相同血液供体的淋巴细胞可以通过逆流淘析使用Lionetti等人(1980)的技术的修改来分离,如前所述(Bobak等人 。,1986)。 从吸入抗凝血剂的单位,可以获得60-120,000个单核细胞。 这些细胞没有被活化并且已经显示在多个研究中适当地能够差别激活。
