Homotypic Interaction and Multimerization of Hepatitis C Virus Core Protein

Analysis of hepatitis C virus core protein interaction domains.

Hepatitis C virus (HCV) core protein forms the internal viral coat that encapsidates the genomic RNA and is enveloped in a host cell-derived lipid membrane. As the single capsid protein, core should be capable of multimerization but attempts to produce virus-like particles following expression of HCV structural proteins have not been successful. In this study, we have analysed the interaction c...

Overexpression of Full-Length Core Protein of Hepatitis C Virus by Escherichia coli Cultivated in Stirred Tank Fermentor

The mature core protein of the Hepatitis C virus (HCVC173) carrying pelB as a signal peptide (PelB::core) was overexpressed in Escherichia coli as 18% and 23.3% of the host’s total protein, in flask and fermentor cultivation, respectively. A final specific yield of 25 ± 1 mg HCVC173/g dry cell weight and an overallproductivity of 51±1 mg HCVC173/l/h were obtained in the stirred-tank ferme...

Interaction of hepatitis C virus core protein with viral sense RNA and suppression of its translation.

To clarify the binding properties of hepatitis C virus (HCV) core protein and its viral RNA for the encapsidation, morphogenesis, and replication of HCV, the specific interaction of HCV core protein with its genomic RNA synthesized in vitro was examined in an in vivo system. The positive-sense RNA from the 5' end to nucleotide (nt) 2327, which covers the 5' untranslated region (5'UTR) and a par...

CpG Motif as an Adjuvant in Immunization of a Recombinant Plasmid Encoding Hepatitis C Virus Core Protein

Hepatitis C virus and skin

Nowadays viral hepatitis is one of the most common and important causes of chronic liver disorders in the world. Extrahepatic manifestations of viral hepatitis consist a main part of the disease. The main viruses causing hepatitis include Hepatitis A, B and C viruses. Herein common skin manifestations in hepatitis C virus (HCV) are discussed. Chronic hepatitis causes skin disorders both directl...
