  • Patent number: 8506750
    Abstract: A composite structure comprising two polytetrafluoroethylene porous layers and a framework structural member having a plurality of gaps or openings, the framework structural member being disposed between the two polytetrafluoroethylene porous layers, wherein the composite structure is structured such that the polytetrafluoroethylene porous layers are united together by being adhered with each other through the gaps or openings of the framework structural member and such that the respective polytetrafluoroethylene porous layers (A1) and (A2) are united with the framework structural member closely along the surfaces of the respective constituent elements of the framework structural member in such a manner as to wrap the respective elements. The method of manufacturing the composite structure is characterized in that it includes a step of applying pressure through a mass of fine particles.

  • Patent number: 6777540
    Abstract: Novel humanized immunoglobulins and active fragments thereof which are specifically reactive to Fas ligand are provided, and a site on Fas ligand which is important to inhibit apoptosis induced by the Fas-Fas ligand interaction against Fas-expressing cells is demonstrated. The novel humanized immunoglobulins and active fragments thereof which are specifically reactive to Fas ligand are prepared from hybridomas which produce monoclonal antibodies specifically reactive to Fas ligand, via recombinant DNA techniques. The humanized immunoglobulins can inhibit the physiological reactions between Fas ligand and Fas such as apoptosis. Further, identification of the site which is on Fas ligand and responsible for apoptosis induction allows creation of recombinant proteins or peptides which are specifically reactive to the amino acids within the site so as to inhibit apoptosis, and to find new therapeutic or diagnostic agents.

  • Patent number: 6426403
    Abstract: This invention relates to a TRAF family molecule, a polynucleotide encoding the molecules, an antibody against the molecules, and an antisense polynucleotide of the molecule. Employing an oligo-DNA primer capable of amplifying the most highly conserved region of a known TRAF family molecule, PCR was performed with the aid of cDNA derived from various cell strains and tissues as a template. Thus, the base sequence of the gene of an unknown TRAF family molecule and the amino acid sequence of the TRAF family molecule encoded by the gene were elucidated. An antibody against the molecule was also prepared. By utilizing the TRAF family molecules, genes thereof, and antibodies against the molecules, there are provided methods for elucidating the functions of the proteins and methods for elucidating the signal transduction system of the TNF-R family involving the molecules, as well as probes for research and diagosis, which suggest applications in therapeutic agents.
