  • Publication number: 20150104466
    Abstract: The present invention relates to methods and compositions for inhibiting the entry of viruses, such as herpesviruses into a host cell. A conserved viral integrin-binding gB disintegrin-like domain has been identified that engages integrins and facilitates viral internalization into the host cell. Therefore, methods and compositions, such as antiviral agents encompassing the conserved gB disintegrin-like domain and antibodies thereto are described. These active agents interfere with the interaction between virions and cellular integrins, thereby inhibiting viral infection of a host cell.

    Abstract: The present invention is a test kit for rapidly diagnosing influenza according to the principles of immunochromatography, and the purpose thereof is to provide a test kit for the influenza A virus in which the sensitivity in detecting the influenza A virus is greater than in conventional test kits, and a determination of “positive” is obtained stably and with high precision at an earlier time during the onset of influenza symptoms. The present invention pertains to a kit for detecting influenza A virus, in which an antibody that is in solid phase in the chromatographic medium enters into an antigen-antibody reaction with native nuclear proteins of the influenza A virus, but in Western blots the antibody does not enter into antigen-antibody reactions with full-length nuclear proteins of the influenza A virus that have been separated using SDS-polyacrylamide gel electrophoresis.

  • Patent number: 8658354
    Abstract: A method of immunoassay of H5 subtype influenza A virus by which the virus can be accurately assayed even in cases where a certain level of mutation has occurred in the H5 subtype influenza A virus, and a kit therefor, and a novel anti-H5 subtype influenza A virus monoclonal antibody which can be used for the immunoassay are disclosed. The antibody or an antigen-binding fragment thereof of the present invention undergoes antigen-antibody reaction with hemagglutinin of H5 subtype influenza A virus, and the corresponding epitope of the antibody or an antigen-binding fragment thereof is located in a region other than the receptor subdomain (excluding C-terminal region thereof consisting of 11 amino acids), which antibody or an antigen-binding fragment thereof does not have neutralizing activity against the influenza A virus.

  • Patent number: 8648176
    Abstract: The present invention features, inter alia, compositions and methods for the treatment of cancer and infectious disease. The compositions include engineered proteins that specifically bind a metal chelate and may be bispecific. For example, the engineered proteins may bind (a) a target (e.g., a cellular protein) on a cancerous cell or a pathogen and (b) a metal chelate comprising DOTA, or an active variant thereof, and a metal ion such as a radionuclide. By virtue of the multiple binding sites, the engineered protein effectively delivers a metal chelate to a cell one wishes to destroy.

  • Patent number: 8647818
    Abstract: Methods and compositions are provided which employ chimeric polypeptides having at least one heterologous epitope for a human immunodeficiency virus type 1 (HIV-1) neutralizing antibody. These chimeric polypeptides behave as molecular scaffolds which are capable of presenting the various heterologous HIV-1 epitopes. The invention demonstrates that a heterologous epitope recognized by the HIV-1 neutralizing antibody can be more fully exposed to neutralizing antibodies when presented within the backbone of the chimeric polypeptide than when the epitope is presented within the context of an HIV-1 backbone. Polynucleotides encoding these chimeric polypeptides are also provided. Immunogenic compositions are provided which comprise a chimeric polypeptide having at least one heterologous epitope that interacts with an HIV-1 neutralizing antibody. Immuno genie compositions comprising chimeric polynucleotides encoding the chimeric polypeptides of the invention are also provided.

  • Patent number: 8637234
    Abstract: Methods and compositions are provided for the use of an envelope polypeptide or a functional variant thereof from a lentivirus that is not HIV-1 as a molecular scaffold for HIV-1 epitopes. The HIV-1 epitopes can be recognized by HIV-1 binding antibodies, HIV-1 neutralizing antibodies and/or CD4-induced antibodies. Thus, methods are provided for detecting HIV-1 binding antibodies in a subject infected with HTV-1. Further provided are methods to determine an epitope for an HIV-1 binding antibody; methods to assay for an HIV-1 binding antibody; methods to identify a soluble CD4 mimic; methods to neutralize an non-HIV-1 virus; diagnostic assays to monitor HIV disease in a subject or to monitor the subject's response to immunization by a HIV vaccine; and methods to alter the neutralization potential of an HIV-1 derived CD4-induced antibody. Chimeric polypeptides, chimeric polynucleotides, kits, cells and viruses are also provided.
