EFFICIENT CELL CULTURE SYSTEM FOR HEPATITIS C VIRUS GENOTYPE 7a

Genotype 7a has been identified recently, thus not much is known about the biology of this new, major HCV genotype. The present inventors developed hepatitis C virus 7a / 2a intergenotypic recombinants in which the JFH1 structural genes (Core, E1 and E2), p7 and the complete NS2 were replaced by the corresponding genes of the genotype 7a strain QC69 and characterized them in Huh7.5 cells. Sequence analysis of 7a / JFH1 recombinants recovered after viral passage in Huh7.5 cells following 4 independent transfection experiments revealed adaptive mutations in Core, E2, NS2, NS5A and NS5B. In reverse genetic studies the importance of these mutations for improved growth kinetics was shown. Adapted 7a / JFH1 viruses showed growth kinetics, infectivity and RNA titers comparable to a previously developed 3a / JFH1 reference virus. Conclusion: The developed 7a / JFH1 viruses provide a robust in vitro tool for research in HCV genotype 7, including vaccine studies and functional analyses.

Efficient cell culture system for hepatitis C virus genotype 1A and 1B

The present inventors developed hepatitis C virus 1a / 2a and 1b / 2a intergenotypic recombinants in which the JFH1 structural genes (Core, E1 and E2), p7 and NS2 were replaced by the corresponding genes of the genotype Ia reference strain H77C or TN or the corresponding genes of the genotype Ib reference strain J4. Sequence analysis of recovered 1a / 2a and 1b / 2a recombinants from 2 serial passages and subsequent reverse genetic studies revealed adaptive mutations in e.g. p7, NS2 and / or NS3. In addition, the inventors demonstrate the possibility of using adaptive mutations identified for one HCV isolate in generating efficient cell culture systems for other isolates by transfer of mutations across isolates, subtypes or major genotypes. Furthermore neutralization studies showed that viruses of e.g. genotype 1 were efficiently neutralized by genotype Ia, 4a and 5a serum, an effect that could be utilized e.g. in vaccine development and immunological prophylaxis. The inventors in addition demonstrate the use of the developed systems for screening of antiviral substances in vitro and functional studies of the virus, e.g. identification of receptors required for HCV entry.

Clinical diagnosis of hepatic fibrosis using a novel panel of low abundant human plasma protein biomarkers

The inventors have proposed a novel panel of human plasma protein biomarkers for diagnosing hepatic fibrosis and cirrhosis. Presently there is no reliable non-invasive way of assessing liver fibrosis. A 2D-PAGE based proteomics study was used to identify potential fibrosis biomarkers. Plasma from patients with hepatic cirrhosis induced by infection with the hepatitis C virus (HCV) were analysed. Several proteins associated with liver scarring and potentially also related to viral infection were identified. These proteins include 14-3-3 protein zeta / delta, adiponectin, afamin, alpha-1-antitrypsin, alpha-2-HS-glycoprotein, apolipoprotein C-M, apolipoprotein E, C4b-binding protein beta chain, intact / cleaved complement C3dg, corticosteroid-binding globulin, fibrinogen gamma chain, beta haptoglobin at pH 5.46-5.49, haptoglobin-related protein, hemopexin, immunoglobulin J chain, leucine-rich alpha-2-glycoprotein, lipid transfer inhibitor protein, retinol-binding protein 4, serum paraoxonase / arylesterase 1, sex hormone-binding globulin and zinc-alpha-2-glycoprotein.
