  • Patent number: 7238356
    Abstract: The current invention relates to HCV envelope proteins or parts thereof which are the product of expression in eukaryotic cells. More particularly said HCV envelope proteins are characterized in that on average up to 80% of their N-glycosylation sites are core-glycosylated. Of these N-glycosylated sites more than 70% are glycosylated with an oligomannose having a structure defined by Man(8 to 10)-GlcNAc(2). Furthermore, the ratio of the oligomannose with structure Man(7)-GlcNAc(2) over the oligomannose with structure Man(8)-GlcNAc(2) is less than or equal to 0.45. Less than 10% of the oligomannoses is terminated with an ?1,3 linked mannose. The HCV envelope proteins of the invention are particularly suited for diagnostic, prophylactic and therapeutic purposes. A suitable eukaryotic cell for production of the HCV envelope proteins of the invention is a Hansenula cell.

  • Patent number: 7196183
    Abstract: The present invention relates to genomic nucleotide sequences and amino acid sequences corresponding to the non-coding and coding region of a new type of HCV. The invention relates to new HCV types and subtypes sequences which are different from the known HCV types and subtypes sequences. Particularly, the present invention relates to said new HCV type sequences; a process for preparing them, and their use for diagnosis, prophylaxis and therapy. More particularly, the present invention provides new type-specific sequences of the 5? NCR, Core, the E1 and the NS5 regions of the new HCV type. These new HCV sequences are useful to diagnose the presence of HCV type genotypes or serotypes in a biological sample. Moreover, the availability of these new type-specific sequences can increase the overall sensitivity of HCV detection and should also prove to be useful for prophylactic and therapeutic purposes.

  • Publication number: 20060275323
    Abstract: The present invention is based on the finding that the envelope proteins of HCV induce a beneficial immune response in chronically HCV-infected chimpanzees. The immunization can preferentially be carried out using HCV envelope proteins in the form of particles which are produced in a detergent-assisted manner. The envelope proteins when presented as such to chronic HCV carriers are highly immunogenic and stimulate both the cellular and humoral immune response.
