  • Publication number: 20220213217
    Abstract: The present inventors produced a variety of bispecific antibodies that specifically bind to both F. IX/F. IXa and F. X, and functionally substitute for F. VIIIa, i.e., have a cofactor function to promote F. X activation via F. IXa. Among these antibodies, the antibody A44/B26 reduced coagulation time by 50 seconds or more as compared to that observed when the antibody was not added. The present inventors produced a commonly shared L chain antibody from this antibody using L chains of A44, and showed that A44L can be used as commonly shared L chains, although the activity of the resulting antibody is reduced compared to the original antibody (A44HL-B26HL). Further, with appropriate CDR shuffling, the present inventors successfully produced highly active multispecific antibodies that functionally substitute for coagulation factor VIII.

  • Patent number: 11056957
    Abstract: A rotary electric machine equipped with a magnetic flux variable mechanism includes a case body, a mover moving upon receipt of centrifugal force, a magnetic flux short circuit member, a cam member, and biasing springs. The cam member includes a cam surface so as to face the mover and make contact with the mover, and the cam member converts a radial movement of the mover received by the cam surface into an axial movement of the magnetic flux short circuit member. The biasing springs give a biasing force to the magnetic flux short circuit member in a direction distanced from an axial end surface of the rotor core, so as to determine a position of the magnetic flux short circuit member along the axial direction in a state where the biasing force is balanced with the centrifugal force applied to the mover via the cam member.
