The DEAD box helicase DDX3 assembles IPS-1 (also called Cardif, MAVS, or VISA) in non-infected human cells where minimal amounts of the RIG-I-like receptor (RLR) protein are expressed. DDX3 C-terminal regions directly bind the IPS-1 CARD-like domain as well as the N-terminal hepatitis C virus (HCV) core protein. DDX3 physically binds viral RNA to form IPS-1-containing spots, that are visible by...
An ELISA was used to detect a protein derived from the core gene of the hepatitis C virus (HCV) in human plasma. The solid phase antibody in the assay was a murine monoclonal antibody against a synthetic peptide deduced from the putative core gene of HCV (residues 39 to 74). An enzyme-labelled affinity-purified human antibody directed at another region within the HCV core (residues 5 to 23) was...
BACKGROUND Many studies have estimated the prevalence of anti-hepatitis C virus (HCV) antibody among hemodialysis (HD) patients; however, the prevalence of HCV core antigen-which indicates the presence of chronic HCV infection-is not known. METHODS Standardized prevalence ratios (SPRs) for anti-HCV antibody and HCV core antigen among HD patients (n = 1214) were calculated on the basis of data...
Four of 107 samples obtained from hepatitis C virus (HCV) carriers showed lower HCV core antigen levels in a fluorescence enzyme immunoassay (FEIA) than expected from corresponding HCV RNA levels. Nucleotide sequencing revealed a mutation in the HCV core region (Thr49Pro) that appears to have reduced the FEIA sensitivity.
Hepatitis C virus (HCV) is a major cause of chronic liver disease that frequently leads to steatosis, cirrhosis, and eventually hepatocellular carcinoma (HCC). HCV core protein is not only a component of viral particles but also a multifunctional protein because liver steatosis and HCC are developed in HCV core gene-transgenic (CoreTg) mice. Proteasome activator PA28gamma/REGgamma regulates hos...
We previously demonstrated that the core protein of hepatitis C virus (HCV) can suppress gene expression and replication of hepatitis B virus (HBV) in a human hepatoma cell line (HuH-7). In this study, we have characterized the phosphorylation property of HCV core protein and examined the effect of phosphorylation on its suppressive activity of HBV. Our results indicated that both the full-leng...
Background. Hepatitis C virus (HCV) genotype 3 is known to cause steatosis (fatty liver) that is more frequent and severe than other genotypes. We previously identified sequence elements within genotype 3 HCV Core domain 3 that were sufficient for lipid accumulation. Aims. We examined various genotype 3 Core domains for lipid droplet localization and compared the lipid droplet binding regions o...
Hepatitis C virus (HCV) is increasingly common among human immunodeficiency virus (HIV)-infected men who have sex with men. We evaluated the efficacy of HCV core antigen in diagnosing acute HCV in an HIV-infected cohort. Compared with HCV polymerase chain reaction, core antigen proved sensitive (100%) and specific (97.9%). As a quick, simple, and cost-effective test, it has considerable utility...
