Domain 3 of hepatitis C virus core protein is sufficient for intracellular lipid accumulation.

Lipid Droplet Binding of Hepatitis C Virus Core Protein Genotype 3

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...

Specific polymorphisms in hepatitis C virus genotype 3 core protein associated with intracellular lipid accumulation.

BACKGROUND Steatosis is a common histological finding and a poor prognostic indicator in patients with hepatitis C virus (HCV) infection. In HCV genotype 3-infected patients, the etiology of steatosis appears to be closely correlated with unknown viral factors that increase intracellular lipid levels. We hypothesize that specific sequence polymorphisms in HCV genotype 3 core protein may be asso...

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

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...

The genotype 3-specific hepatitis C virus core protein residue phenylalanine 164 increases steatosis in an in vitro cellular model.

BACKGROUND AND AIMS The prevalence and severity of liver steatosis are higher in patients infected with genotype 3 hepatitis C virus (HCV) than in patients infected with other genotypes. HCV core protein is known to affect lipid metabolism, inducing lipid droplet accumulation both in vitro and in vivo. An in vitro cellular model was used to investigate whether an HCV core protein with residues ...
