  • Patent number: 8906384
    Abstract: A member of the bovine type III IFN family, boIFN-?3, was identified and characterized. We expressed boIFN-?3 using a recombinant replication defective human adenovirus type 5 (Ad5) and demonstrated antiviral activity against foot-and-mouth disease virus (FMDV) and vesicular stomatitis virus (VSV) in bovine cells in vitro. Cattle were inoculated with Ad5-boIFN-?3 followed by intradermolingual or aerosol FMDV challenge. Results demonstrated that the type III IFN family is conserved in bovines and that treatment of cattle with boIFN-?3 alone or in combination with IFN-? is able to confer delayed and reduced severity of FMD. Furthermore inoculation with Ad5-boIFN-?3 alone conferred full protection against aerosol challenge for at least 7 days after administration suggesting that type III IFN used in combination with FMD vaccines could fill one of the current gaps in emergency vaccination against FMDV.

  • Patent number: 7888475
    Abstract: Herein is described a system to combat poxvirus infection wherein antagonists are developed that bind the soluble cytokine receptor but have no significant biological activity in the host, effectively blocking the virus-mediated suppressor of interferon function, thereby permitting the host's own cytokines to stimulate an antiviral response. Alternatively, interferon molecules can be developed that retain biological activity on their native receptors but fail to bind the viral cytokine binding protein, thereby circumventing this virus immune modulation mechanism.

  • Patent number: 7884264
    Abstract: Methods for altering the N-glycosylation pattern of proteins in higher plants are provided. In some embodiments, the methods comprise introducing into a duckweed plant a recombinant RNAi construct that provides for the inhibition of expression of ?1,3-fucosyltransferase (FucT) and ?1,2-xylosyltransferase (XylT). Use of these RNAi constructs to inhibit or suppress expression of both of these enzymes, and isoforms thereof, advantageously provides for the production of endogenous and heterologous proteins having a “humanized” N-glycosylation pattern without impacting plant growth and development. Stably transformed higher plants, including duckweed plants, having this protein N-glycosylation pattern are provided. Glycoprotein compositions, including monoclonal antibody compositions, having substantially homogeneous glycosylation profiles, and which are substantially homogeneous for the G0 glycoform, are also provided.

  • Patent number: 7879326
    Abstract: A panel of IgG1 human monoclonal antibodies (HMAbs) identified by hemagglutination inhibition (HI) assay has been produced from peripheral B cells of an individual immunized with prototype H5N1 vaccine. Sequence analysis of antibody clones showed three clusters of different HMAbs as represented by HMAbs designated as BF1-1, BF1-19 and BF1-10. BF1-1 and BF1-10 have distinct CDR 1, 2 and 3 regions of both heavy and light chains. BF1-19 has the same heavy chain as BF1-1 but the light chain of BF1-10. Antibody binding affinity, KD, studies showed all three HMAbs ranging from at least about 10?8 to at least about 10?9. In vivo protection studies showed that these antibodies afforded significant protection against infection. These findings demonstrate that the antibodies of the invention are cross-neutralizing and therapeutic.

  • Patent number: 7867482
    Abstract: This application relates to recombinant human interferon-like proteins. In one embodiment a recombinant protein created by gene shuffling technology is described having enhanced anti-viral and anti-proliferative activities in comparison to naturally occurring human interferon alpha 2b (HuIFN-?2b). The invention encompasses a polynucleotide encoding the protein and recombinant vectors and host cells comprising the polynucleotide. Preferably the polynucleotide is selected from the group of polynucleotides each having a sequence at least 93% identical to SEQ ID: No. 1 and the protein is selected from the group of proteins each having an amino acid sequence at least 85% identical to SEQ ID No: 2. The proteins and compositions comprising the proteins can be used for treatment of conditions responsive to interferon therapy, such as viral diseases and cancer.
