  • Patent number: 8481298
    Abstract: The present invention relates to a method of preparing a separation matrix comprising at least one insoluble carrier to which sulphate ligands have been attached via extenders, which method comprises coupling, in a first step, of the sulphate ligands to the extenders and, in a subsequent step, attaching the extenders to an insoluble carrier. The invention also relates to a separation matrix comprised of at least one insoluble carrier to which sulphate ligands have been attached via extenders. Advantageously, no sulphate ligands are directly attached to the insoluble carrier. The extenders may be natural polymers, such as dextran, and the insoluble carrier may be made from natural polymers, such as agarose, or synthetic polymers. The invention also relates to a method of purifying virus, such as influenza virus, using a separation matrix according to the invention.

  • Patent number: 8460933
    Abstract: The invention provides a method for enhancing expression of a transgene in a host cell, which includes the steps of inserting a capsid promoter element (Pcap), or a sequence comprising the reverse complement of the capsid promoter element (PcapR), into a mammalian expression cassette upstream (5?) of a cytomegalovirus immediate/early enhancer/promoter region (Pcmv); inserting the transgene into the expression cassette downstream (3?) of the cytomegalovirus immediate/early enhancer/promoter region; inserting a vector containing the expression cassette into the host organism; and causing expression of the transgene. The capsid promoter element (Pcap) is typically from a circovirus, parvovirus or anellovirus. The transgene is typically expressed at a higher level than when expressed by a vector containing the expression cassette without the transcriptional control element. An expression cassette, vector, DNA vaccine, pharmaceutical composition and method of treatment are also claimed.

  • Patent number: 8460674
    Abstract: The invention provides HSV antigens and epitopes that are useful for the prevention and treatment of HSV infection. T-cells having specificity for antigens of the invention have demonstrated cytotoxic activity against cells loaded with virally-encoded peptide epitopes, and in many cases, against cells infected with HSV. The identification of immunogenic antigens responsible for T-cell specificity provides improved anti-viral therapeutic and prophylactic strategies. Compositions containing antigens or polynucleotides encoding antigens of the invention provide effectively targeted vaccines for prevention and treatment of HSV infection.

  • Patent number: 8454974
    Abstract: The present inventors developed three 4a/2a intergenotypic recombinants in which the JFH1 structural genes (Core, E1 and E2), p7 and all of or part of NS2 were replaced by the corresponding genes of the genotype 4a reference strain ED43. The 4a/2a junction in NS2 was placed after the first transmembrane domain (?), in the cytoplasmic part (?) or at the NS2/NS3 cleavage site (y). Following transfection of Huh7.5 cells with RNA transcripts, infectious viruses were produced in the ED43/JFH1-? and -y cultures only. Compared to the 2a control virus, production of infectious viruses was significantly delayed. However, in subsequent passages efficient spread of infection and high HCV RNA titers were obtained. Infectivity titers were approximately 10-fold lower than for the 2a control virus. Sequence analysis of recovered 4a/2a recombinants from 3 serial passages and subsequent reverse genetic studies revealed a vital dependence on a mutation in the NS2 4a part. ED43/JFH1-? further depended on a second NS2 mutation.

  • Patent number: 8440202
    Abstract: The invention relates to methods for the induction of an immune response to dengue virus. The method of inducing an immune response against dengue virus comprises administration of a non-replicating immunogen followed by a boost with a tetravalent live attenuated viral vaccine. Another aspect of the inventive subject matter is a method of inducing an immune response against dengue virus using a heterologous prime-boost regimen with the priming immunogen comprising a DNA expression system, an adenovirus expression vector or a Venezuelan equine encephalitis virus replicon system and the boosting immunogen comprising the same without the DNA expression system. Each expression system contains DNA sequences encoding dengue viral proteins.

  • Patent number: 8426125
    Abstract: The present invention provides a method of pretreating a specimen, which allows measurement according to an immunoassay to be carried out on a specimen from nasal secretion while preventing non-specific reactions. According to this method, the specimen from nasal secretion is treated with a protease beforehand and then an immunoassay is performed. As the protease, it is preferable to use semi-alkaline protease (EC 3.4.21.63). Furthermore, it is preferable that a substance to be pretreated by the pretreatment method according to the present invention is an influenza virus contained in the specimen from nasal secretion. The immunoassay preferably is an immunoagglutination assay. Examples of the immunoagglutination assay include a turbidimetric immunoassay, a latex turbidimetric immunoassay, and a latex agglutination assay that is performed on a slide glass.
