  • Patent number: 8776927
    Abstract: A vehicle battery pack housing structure includes a vehicle body panel and first, second and third panel components that define an outward-opening battery housing space. The first panel component is rigidly attached to the vehicle body panel and includes a first side wall and a base wall. The second panel component is rigidly attached to the first panel component and includes a second side wall and a first periphery wall portion. The third panel component is rigidly attached to the second panel component. The third panel component includes a second periphery wall portion that cooperates with the first periphery wall portion to form a periphery wall portion when the third panel component is rigidly attached to the second panel component.

  • Publication number: 20140046034
    Abstract: An object of the present invention is to provide an antibody inhibiting infection with hepatitis C virus (HCV). The present invention provides an anti-hepatitis C virus antibody that recognizes a whole or a part of the conformation of a hepatitis C virus particle as an epitope and binds thereto, so as to be able to inhibit the binding of hepatitis C virus to the surface of a host cell and to inhibit HCV infection, a humanized antibody thereof, and an inhibitory agent for infection with hepatitis C virus.

  • Patent number: 8604179
    Abstract: This invention provides infectious chimeric HCV particles that can be used for vaccines. This invention further provides a nucleic acid comprising a chimeric gene derived from the hepatitis C virus comprising regions each encoding Core protein, E1 protein, E2 protein and p7 protein derived from a hepatitis C virus strain other than JFH-1 strain; NS2 protein derived from JFH-1 strain or a hepatitis C virus strain other than JFH-1 strain, or a chimeric NS2 protein of NS2 protein derived from JFH-1 strain and NS2 protein derived from a hepatitis C virus strain other than JFH-1 strain; and NS3 protein, NS4A protein, NS4B protein, NS5A protein, and NS5B protein derived from JFH-1 strain in that order in 5? to 3? direction, wherein the 328th proline residue from the amino acid residue at N-terminus of the Core protein is substituted with an amino acid residue other than proline. This invention further provides chimeric HCV particles comprising such nucleic acid, and use of such HCV particles for vaccines.

  • Publication number: 20120251572
    Abstract: A combination of an HCV antigen for inducing an antibody having the activity of inhibiting HCV infection and an optimum adjuvant is discovered, so as to provide an effective HCV vaccine composition. The hepatitis C virus vaccine composition comprises: inactivated viral particles obtained by inactivating infectious hepatitis C virus particles prepared from hepatitis C virus genome that contains sequences encoding NS3 protein, NS4A protein, NS4B protein, NS5A protein and NS5B protein derived from hepatitis C virus JFH1 strain; an oligonucleotide containing unmethylated CpG, according to SEQ ID NO: 5 in the sequence listing; and aluminium hydroxide.
