A major function of the hepatitis C virus (HCV) core protein is the interaction with genomic RNA to form the nucleocapsid, an essential component of the virus particle. Analyses to identify basic amino acid residues of HCV core protein, important for capsid assembly, were initially performed with a cell-free system, which did not indicate the importance of(More)
In infected cells, hepatitis C virus (HCV) induces the formation of membrane alterations referred to as membranous webs, which are sites of RNA replication. In addition, HCV RNA replication also occurs in smaller membrane structures that are associated with the endoplasmic reticulum. However, cellular mechanisms involved in the formation of HCV replication(More)
BACKGROUND The envelope glycoprotein E2 of hepatitis C virus (HCV) contains several hypervariable regions. Interestingly, 2 regions of intragenotypic hypervariability within E2 have been described as being specific to HCV subtype 3a. Based on their amino acid position in E2, they were named HVR495 and HVR575. Here, we further investigated these regions in(More)
Core plays a critical role during hepatitis C virus (HCV) assembly, not only as a structural component of the virion, but also as a regulator of the formation of assembly sites. In this study, we observed that core is expressed later than other HCV proteins in a single viral cycle assay, resulting in a relative increase of core expression during a late step(More)
UNLABELLED In hepatitis C virus (HCV)-infected cells, the envelope glycoproteins E1 and E2 assemble as a heterodimer. To investigate potential changes in the oligomerization of virion-associated envelope proteins, we performed SDS-PAGE under reducing conditions but without thermal denaturation. This revealed the presence of SDS-resistant trimers of E1 in(More)
West Nile virus (WNV) is the most widespread arbovirus in the world. Several recent outbreaks and epizootics have been reported in Europe and the Mediterranean basin with increased virulence. In contrast to the well-characterized American and Australian strains, little is known about the virulence determinants of the WNV European-Mediterranean strains. To(More)
Cytoplasmic inclusions are found in a variety of diseases that are characteristic morphological features of several hepatic, muscular and neurodegenerative disorders. They display a predominantly filamentous ultrastructure that is also observed in malignant rhabdoid tumor (MRT). A cellular clone containing an intracytoplasmic body was isolated from(More)
