  • Patent number: 11927024
    Abstract: A binding machine includes: a wire feeding unit configured to feed a wire; a curl forming unit configured to form a feeding path of the wire along which the wire fed in a first direction by the wire feeding unit is wound around an object; and a binding unit configured to twist the wire fed in first direction by the wire feeding unit and wound on the object. The wire feeding unit includes a pair of feeding members configured to sandwich the wire and to feed the wire by a rotating operation, and a feeding motor configured to drive the feeding members. The binding machine further includes a control unit configured to control the wire feeding unit. The control unit is configured to control the wire feeding unit to enable the wire sandwiched by the feeding members to be discharged from the feeding members.

  • Patent number: 11612149
    Abstract: The present invention provides genetically modified non-human animals which are deficient in at least one or more types of CD3 genes selected from the group consisting of endogenous CD3?, CD3?, and CD3? in its genome and functionally express at least one or more types of human CD3 genes selected from the group consisting of human CD3?, CD3?, and CD3?. In the genetically modified non-human animals of the present invention, mature T cell differentiation and production can take place, and immunocompetent cells including T cells can exert their functions. The genetically modified non-human animals of the present invention enable efficient evaluation and screening in the development of therapeutic agents and therapeutic methods that use human CD3-mediated targeted drugs.

  • Patent number: 11505605
    Abstract: It was discovered that antigen-binding molecules comprising (i) a domain that binds to a molecule expressed on the surface of cells having immune response-suppressing functions, and (ii) a T cell receptor complex-binding domain exhibit more superior antitumor effects than conventional antigen-binding molecules by crosslinking T cells with cells having immune response-suppressing functions, and damaging the cells having immune response-suppressing functions.

  • Publication number: 20220348658
    Abstract: The present disclosure provides combination therapies with an anti-T cell antigen-binding molecule and a cytokine inhibitor. Antibodies that recruit T cells as effector cells into tumor tissues are called T cell redirecting antibodies, and are known as means for treating tumors. On the other hand, when systemic cytokine production is stimulated by binding of antibodies to T cells, it is feared that this systemic action will lead to aberrations such as CRS. The present disclosure provides means for alleviating systemic cytokine production, and will enable safer use of anti-T cell antigen-binding molecules in tumor treatment.
