This technology relates to compositions and methods for improving the growth characteristics of cells engineered to produce live viruses such as the Influenza virus. Featured is a method that uses the gene candidate, siat7e, or its expressed or inhibited products in Madin Darby Canine Kidney (MDCK) cells. The gene expression modulates anchorage-dependence of the cell line thereby allowing scale-up on bioreactor platforms without the use of microcarrier beads and reducing production costs.

Japanese encephalitis virus (JEV) is the prototype virus of the Japanese encephalitis (JE) group belonging to the Flavivirus genus of the Flaviviridae family. Other members of the group include Kunjin virus, St. Louis encephalitis virus, and West Nile encephalitis virus (WNV). JEV is widely distributed in South Asia, Southeast Asia, and the Asian Pacific Rim. In recent years, JE epidemics have spread to previously unaffected areas, such as northern Australia, Pakistan, India and Indonesia.

NIH investigators, for the first time, identified specific mutations associated with stuttering. These mutations are located within the genes encoding three enzymes, Glc-NAc phosphotransferase catalytic subunit [GNPTAB], Glc-NAc phosphotransferase recognition subunit [GNPTG], and N-acetylglucosamine-1-phosphodiester alpha-N-acetylglucosaminidase [NAGPA]. Together these constitute the pathway that targets lysosomal enzymes to their proper location.

The technology offered for licensing is foundational in the area of recombinant DNA vaccines. In the last several years, facilitated through a licensing program of the NIH, the technology has been broadly applied in the development and commercialization of several novel human and veterinary vaccines in the areas of infectious disease as well as cancer therapeutics. The NIH wishes to expand its licensing program of the subject technology in a variety of applications that will benefit public health.

The tick-borne encephalitis virus (TBEV) complex is a group of viruses that can cause severe neutrotropic disease and up to thirty percent (30%) mortality. While these viruses can be found in many parts of the world, the largest impact of the disease occurs in Europe and Russia, where approximately fourteen thousand (14,000) hospitalized TBEV cases occur annually. TBEV is in the family Flaviviridae, genus flavivirus and is composed of a positive-sense single stranded RNA genome that contains 5' and 3' non-coding regions and a single open reading frame encoding ten (10) proteins.

Offered for licensing is a recombinant attenuated vaccinia virus, MVA, that expresses the haemagglutinin (HA) and nucleoprotein (NP) of influenza virus A/PR/8/34 (H1N1). The virus has been shown to stimulate protective immunity to influenza virus in mice.

The materials can be used for research purposes and in particular in the area of influenza virus vaccines.

The related publications listed below demonstrate the usefulness of this biological material in influenza virus vaccine research.

Bacillus anthracis is the causative agent of anthrax and is surrounded by a polypeptide capsule of poly-gamma-D-glutamic acid (gammaDPGA). gammaDPGA is poorly immunogenic and has antiphagocytic properties. The bacterial capsule is essential for virulence. Antibodies to the capsule have been shown to enhance phagocytosis and killing of encapsulated bacilli. These antibodies in combination with antibodies that neutralize the toxins of B. anthracis could provide enhanced protection by their dual antibacterial and antitoxic activities.

Offered for licensing is a recombinant attenuated vaccinia virus, MVA, that expresses SIV 239gagpol. The materials can be used for research purposes and in particular in the area of HIV/AIDS vaccines.

The invention offered for licensing is in the field of use of vaccines for malaria. The invention provides gene sequences encoding an erythrocyte binding protein of a malaria pathogen for the expression of the erythrocyte binding protein. The codon composition of the synthetic gene sequences approximates the mammalian codon composition. The synthetic gene sequences are useful for incorporation into DNA vaccine vectors, for the incorporation into various expression vectors for production of malaria proteins, or both.

Moraxella catarrhalis is one of the three leading causative agents of otitis media in children. This is due in part to the current immunizations of children with Streptococcus pneumoniae polysaccharide and conjugate vaccines to prevent otitis media. The proportion of otitis media caused by pneumococcal strains covered by the vaccines have decreased while those caused by Moraxella catarrhalis and nontypeable Haemophilus influenzae have significantly increased.
