  • Publication number: 20210221875
    Abstract: The present invention provides a polypeptide comprising an antigen binding domain which binds to an antigen present in cartilage tissue, and also provides use of the polypeptide. The polypeptide of the invention is useful for penetrating and/or retaining a desired substance in the cartilage tissue for a long period. The present invention further relates to a polypeptide comprising (i) an antigen binding domain which binds to a molecule in a cartilage tissue, and (ii) a carrying moiety having an inhibiting domain that inhibits the antigen binding activity of the antigen binding domain, and having a longer half-life than that of the antigen binding domain existing alone, and a pharmaceutical composition comprising the polypeptide. The present invention further relates to methods for producing and screening for the polypeptide.

  • Patent number: 9745378
    Abstract: The present inventors obtained, from a phage library of human antibodies, an anti-mouse NR 10 neutralizing antibody-expressing BM095 clone that shows a strong proliferation-suppressing activity in an IL-31-dependent Ba/F3 cell proliferation assay system. When this anti-mouse NR 10 neutralizing antibody was administered to NC/Nga mice, a model of atopic dermatitis which is a mouse model of chronic dermatitis that arises as a result of repeated applications of picryl chloride, a mouse model of rheumatoid arthritis, and a mouse model of osteoarthritis, a significant effect of symptom suppression was observed. This revealed that the anti-NR 10 neutralizing antibody is indeed effective as a therapeutic agent for inflammatory diseases. In addition, the present inventors successfully obtained an anti-human NR 10 neutralizing antibody, providing extremely useful therapeutic agents with practical clinical applications.
