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.

  • Patent number: 8513397
    Abstract: Plant viral vectors have great potential in rapid production of proteins, but no simple. Here a geminivirus-based system for high-yield and rapid production of oligomeric protein complexes, including virus-like particle (VLP) vaccines and monoclonal antibodies (mAbs) is described. In particular, a single vector that contains two non-competing replicons for transient expression in Nicotiana benthamiana leaves is described. The correct assembly of these subunit proteins into functional oligomeric structures (VLPs or full-size mAb) is also described. This system advances plant transient expression technology by eliminating the need for non-competing viruses, and thus, enhances the realistic commercial application of this technology for producing multiple-subunit protein complexes.

  • Publication number: 20130210150
    Abstract: The present invention provides Sendai virus vectors in which genes that encode reprograming factors for inducing pluripotent stem cells are incorporated in a specific order, compositions comprising these vectors for gene delivery to be used in the induction of pluripotent stem cells, and uses thereof. Incorporation of the KLF gene, OCT gene, and SOX gene in a specific order into a single Sendai virus vector successfully and significantly increased the efficiency of pluripotent stem cell induction. Loading multiple reprogramming factors into a single vector can further increase the induction efficiency of pluripotent stem cells while reducing the number of necessary vectors.

  • Publication number: 20130209395
    Abstract: Provided herein are nucleic acid sequences encoding hepatitis B virus (HBV) core proteins, surface antigen proteins, fragments and combinations thereof as well as genetic constructs/vectors and vaccines that express said protein sequences. These vaccines are able to induce an immune response peripherally and in the liver by recruiting both cellular and humoral agents. Also provided are methods for prophylactically and/or therapeutically immunizing individuals against HBV. The combination vaccine can also be used for particular design vaccines for particular levels of immune responses to HBV challenge.

  • Publication number: 20130195915
    Abstract: A novel influenza C virus with only low homology to any influenza C virus previously characterized. Challenge studies show that the virus can infect pigs and be transmitted between pigs. Additionally, influenza C is commonly thought of as a human pathogen and serological studies have been performed, looking at the incidence of antibodies against this virus in both pigs and humans. Approximately 10% of pigs and 30% of humans have antibodies to this virus. Additional experimental data show that the virus can infect and transmit in ferrets (a surrogate for human infection studies). In a third aspect, the present invention is the partial genome of this novel influenza C virus. In another aspect, the present invention is a method of detection in animals of this novel influenza C virus.
