  • Publication number: 20140370018
    Abstract: Various bispecific antibodies that specifically bind to both blood coagulation factor IX/activated blood coagulation factor IX and blood coagulation factor X and functionally substitute for the cofactor function of blood coagulation factor VIII, that is, the function to promote activation of blood coagulation factor X by activated blood coagulation factor IX, were produced. From these antibodies, multispecific antigen-binding molecules having a high activity of functionally substituting for blood coagulation factor VIII were successfully discovered.

  • Publication number: 20140248282
    Abstract: As a result of producing anti-DDR1 antibodies and conducting extensive studies on the antitumor activity thereof, antibodies that bind to the stalk domain in the amino acid sequence of human DDR1 were found to have a potent activity even when used alone compared to antibodies that bind to other domains. It was also found that the antibodies have one or more activities selected from the group consisting of: (i) an activity to suppress cell proliferation, (ii) an activity to inhibit cell migration, (iii) an activity to inhibit phosphorylation of DDR1 in cells, (iv) an activity to be taken up into cells, (v) an activity to decrease the expression level of DDR1 in cells, and (vi) an activity to decrease the expression level of TGF-? in cells.

  • Patent number: 8252287
    Abstract: For the first time, the present invention provides antibodies that enhance the generation of activated blood coagulation factor VIII. The antibodies enhance the cleavage of blood coagulation factor VIII at the Arg of position 372 and suppress the cleavage at the Arg of position 336 by recognizing and binding to the A2 domain of blood coagulation Factor VIII. Such antibodies are expected to be useful in preventing or treating diseases that develop or progress due to decrease or loss of the blood coagulation factor VIII activity, for example, hemophilia A, acquired hemophilia, and von Willebrand's disease.

  • Patent number: 7517965
    Abstract: The present invention provides anti-aPC antibodies that suppress the inactivation of activated protein C (aPC), and uses thereof. The present inventors screened anti-aPC antibodies, and succeeded in isolating anti-aPC antibodies comprising the activity of suppressing aPC inactivation in blood. The antibodies of the present invention can be used to maintain aPC activity by suppressing aPC inactivation, and can thus be used to sustain aPC bioactivities, such as the activity of suppressing activation of the blood coagulation system, and anti-inflammatory activity. In addition, the present invention provides uses of the antibodies of the present invention in aPC therapy for diseases such as thrombosis and sepsis. The therapeutic effect of aPC can be prolonged in treatment that uses aPC administration by allowing an antibody of the present invention to bind with aPC. The antibodies of the present invention can be used in the treatment and prevention of diseases such as thrombosis and sepsis.

  • Patent number: 5147515
    Abstract: A method for forming a ceramics film on the surface of a substrate comprises performing spark discharge in an electrolytic bath, wherein the electrolytic bath comprises an aqueous solution of a water-soluble or colloidal silicate and/or an oxyacid salt to which ceramics fine particles and/or specific fine particles are dispersed and the spark discharge is carried out in the electrolytic bath while ensuring the suspended state of the ceramics particles and/or the specific fine particles in the electrolytic bath. The method makes it possible to effectively form, on the surface of a metal substrate, ceramics films having a variety of color tones as well as excellent insulating properties and hardness. Moreover, it further makes it possible to effectively form a composite ceramics film having excellent wear resistance on the surface of a metal substrate.
