The method comprises introducing a first nucleic acid and a second nucleic acid into the plant, or portion of the plant. The first nucleic acid comprises a first regulatory region active in the plant and operatively linked to a nucleotide sequence encoding a structural virus protein. The second nucleic acid comprises a second regulatory region active in the plant and operatively linked to a nucleotide sequence encoding a channel protein, for example but not limited to a proton channel protein. The plant or portion of the plant is incubated under conditions that permit the expression of the nucleic acids, thereby producing the VLP.Type: ApplicationFiled: September 28, 2012Publication date: April 16, 2015Inventors: Marc-Andre D'Aoust, Manon Couture, Louis-Philippe Vezina

Publication number: 20150104477Abstract: A method of inducing a specific immune response in a mammal, comprising: providing a first composition comprising isolated ubiquitinylated proteins in solution in the absence of membrane bound organelles, the isolated ubiquitinylated proteins comprising one or more specific antigens, and further comprising a threshold quantity of polyubiquitinylated short-lived proteins and polyubiquitinylated defective ribosomal products. The isolated ubiquitinylated proteins are affinity-purified from tumor-derived cells grown in culture, the tumor-derived cells being inhibited from degrading ubiquitinylated proteins via the proteasome while being grown in culture. In this way, highly immunogenic short-lived proteins and defective ribosomal products may be loaded onto dendritic cells for cross-presentation and priming of antigen-specific T cells restricted by either classical or non-classical MHC.Type: ApplicationFiled: October 10, 2014Publication date: April 16, 2015Inventors: Christopher Twitty, Erik LeShane, Bernard Fox, Hong-Ming Hu, Guangjie Yu

Publication number: 20150104830Abstract: The invention provides a process for generating an avian cell line of duck origin by a process comprising: —cultivating embryonic avian cells in cell culture medium, preferably comprising fetal calf serum (FBS) for more than 40 passages while reducing the concentration of FBS to 1-2% vol/vol FBS, —transferring passaged cells into cell culture medium having 0% FBS, —resulting in the generation of a non-embryonic avian cell line suitable for non-adherent growth, i.e. for growth in suspended culture.Type: ApplicationFiled: May 2, 2013Publication date: April 16, 2015Inventors: Manfred Wirth, Lijing Sun, Zhiguo Su, Roland Riebe, Jaeger Volker, Nadine Konisch

Patent number: 8999347Abstract: The present invention relates to a novel lipoprotein particle, methods for preparing and purifying the same, its use in medicine, particularly in the prevention of malarial infections, compositions/vaccines containing the particle or antibodies against the protein particle such as monoclonal or polyclonal antibodies and use of the same, particularly in therapy. Furthermore, particles with the specific ratio can be prepared by employing yeast, Saccharomyces cerevisiae or Pichia pastoris. In particular it relates to an immunogenic protein particle comprising the following monomers: a. a fusion protein comprising sequences derived from a CS protein of P. vivax and the S antigen of Hepatitis B (CSV-S), and b. S antigen derived from Hepatitis B virus, and characterized in that the ratio of S to CSV-S is in the range 0.1 to 1. Suitably, the ratio of S to CSV-S is in the range 0.19 to 0.30 or 0.68 to 0.80.Type: GrantFiled: December 22, 2008Date of Patent: April 7, 2015Assignee: GlaxoSmithKline Biologicals, SAInventors: Joseph D Cohen, Martine Marchand
