    Abstract: The present invention relates, in general, to attenuated negative-strand RNA viruses having an impaired ability to antagonize the cellular interferon (IFN) response, and the use of such attenuated viruses in vaccine and pharmaceutical formulations. The invention also relates to the development and use of IFN-deficient systems for selection of such attenuated viruses. In particular, the invention relates to attenuated influenza viruses having modifications to the NS1 gene that diminish or eliminate the ability of the NS1 gene product to antagonize the cellular IFN response. The mutant viruses replicate in vivo but demonstrate reduced pathogenicity, and therefore are well suited for live virus vaccines, and pharmaceutical formulations.

  • Publication number: 20090155308
    Abstract: The present invention relates to an adjuvant comprising a lipopeptide and poly I:C. When the adjuvant of the present invention is used, the level of antigen specific antibody induction is synergistically increased and Th1 type immune response is also induced. Therefore, the adjuvant of the present invention can be very effectively used as an adjuvant in the formulation of preventive and therapeutic vaccines for viral or parasitic infection and cancer.

  • Publication number: 20090130144
    Abstract: The present invention provides methods for eliciting an effective immune response against a weakly immunogenic disease or for priming T cells to become memory T cells against a weakly immunogenic disease by directly vaccinating into the bone marrow of the patient an antigen associated with the weakly immunogenic disease. Also included in the present invention is an isolated population of human memory CD8+ T cells from the bone marrow which is in a heightened activation state with a unique effector phenotype.

  • Patent number: 7534596
    Abstract: A method of making a vaccine using animal derived component free (ADCF) cell culture technology, including the steps of attaching ADCF-adapted cells to a microcarrier including an attachment mechanism for attaching filipodia of the cells, the microcarrier being in a culture, growing the cells in ADCF maintenance media, infecting the cells with vaccine media, producing virus within the cells, and harvesting the virus. A vaccine produced by the above method in a pharmaceutically acceptable carrier. A vaccine production structure of ADCF-adapted cells removably attached to microcarrier beads including an attachment mechanism for attaching filipodia of the cells.

  • Publication number: 20090123367
    Abstract: The invention relates to the discovery of novel soluble neutral active Hyaluronidase Glycoproteins (sHASEGPs), methods of manufacture, and their use to facilitate administration of other molecules or to alleviate glycosaminoglycan associated pathologies. Minimally active polypeptide domains of the soluble, neutral active sHASEGP domains are described that include asparagine-linked sugar moieties required for a functional neutral active hyaluronidase domain. Included are modified amino-terminal leader peptides that enhance secretion of sHASEGP. The invention further comprises sialated and pegylated forms of a recombinant sHASEGP to enhance stability and serum pharmacokinetics over naturally occurring slaughterhouse enzymes. Further described are suitable formulations of a substantially purified recombinant sHASEGP glycoprotein derived from a eukaryotic cell that generate the proper glycosylation required for its optimal activity.
