The core protein of hepatitis c virus (HCV) is a structural protein with potent RNA chaperoning activities mediated by its hydrophilic N-terminal domain D1, which is thought to play a key role in HCV replication. To further characterize the core chaperoning properties, we studied the interactions between core D1 and the conserved HCV 3'X genomic region required for genome replication. To this e...
Hepatitis C virus (HCV) assembly remains a poorly understood process. Lipid droplets (LDs) are thought to act as platforms for the assembly of viral components. The JFH1 HCV strain replicates and assembles in association with LD-associated membranes, around which viral core protein is predominantly detected. In contrast, despite its intrinsic capacity to localize to LDs when expressed individua...
Screening and evaluating anti- hepatitis C virus (HCV) drugs in vivo is difficult worldwide, mainly because of the lack of suitable small animal models. We investigate whether zebrafish could be a model organism for HCV replication. To achieve NS5B-dependent replication an HCV sub-replicon was designed and created with two vectors, one with HCV ns5b and fluorescent rfp genes, and the other cont...
Previous studies demonstrate that soluble HIV proteins impact both hepatocyte function and HCV replication in vitro. It has also been reported that HIV can productively infect hepatocytes. We therefore investigated the impact of HIV infection of hepatocytes on HCV expression. The Huh7.5JFH1 cell line that constitutively expresses infectious HCV was infected with the lab-adapted strains HIVNL4-3...
Translation initiation of hepatitis C virus (HCV) RNA occurs through an internal ribosome entry site (IRES) located at its 5' end. As a positive-stranded virus, HCV uses the genomic RNA template for translation and replication, but the transition between these two processes remains poorly understood. HCV core protein (HCV-C) has been proposed as a good candidate to modulate such a regulation. H...
Current therapies for the treatment of hepatitis C virus (HCV) infection are only effective in a restricted number of patients. Cellular immune responses, particularly those mediated by CD8(+) CTLs, are thought to play a role in the control of infection and the response to antiviral therapies. Because the Core protein is the most conserved HCV protein among genotypes, we evaluated the ability o...
Hepatitis viral infection is a leading cause of chronic hepatitis, cirrhosis, and hepatocellular carcinoma (HCC). Over one million people are estimated to be persistently infected with hepatitis C virus (HCV) worldwide. As capsid core protein is the key element in spreading HCV; hence, it is considered to be the superlative target of antiviral compounds. Novel drug inhibitors of HCV are in need...
Hepatitis C virus (HCV) is a major healthproblem with a prevalence of 1% in the United States population, and a significant percentage of infected patients progress to chronic liver disease and cirrhosis. Interferon therapy has demonstrated that the immune system can be modulated to alter the acute course of the disease, but long-term treatments remain elusive. Prevention of hepatitis C infecti...
background and aims: dna constructs containing hcv antigens have become one of the vaccine candidates for induction of anti-hcv cellular and humoral immunity. in this study, we constructed a novel expressing vector harboring a fusion sequence derived from an overlapping fragment in the middle of ns3 and a truncated core fragment to avoid troubles reported to be associated with full gene express...
RNA interference (RNAi) represents a promising strategy for the treatment of HCV infection. However, the development of an effective system for in vivo delivery of small interfering RNA (siRNA) to target organ remains a formidable challenge. Here, we develop a unique nanoparticle platform (VE-DC) composed of α-tocopherol (vitamin E) and cholesterol-based cationic liposomes (DOTAP-Chol) for syst...
