  • Publication number: 20210054061
    Abstract: Provided is a substance capable of effectively suppressing cancer metastasis or a pharmaceutical composition that effectively acts on an inflammatory disease. The pharmaceutical composition is a pharmaceutical composition containing, as an active ingredient, an antibody or an antibody fragment thereof having antigen-binding activity for an S100A8/A9 heterodimer, and blocks interaction between S100A8/A9 and a group of receptors therefor, to thereby strongly suppress cancer metastasis both in vitro and in vivo, or alleviate inflammation. That is, the anti-S100A8/A9 antibody or the antibody fragment thereof can strongly suppress cancer metastasis or alleviate inflammation, by virtue of its blocking action on the interaction between S100A8/A9 and the group of receptors therefor.

  • Publication number: 20210040478
    Abstract: The present invention provides methods for retaining and expressing physiologically active substances in a target tissue-specific-manner, by administering the physiologically active substances to target submucous tissue. Specifically, the present inventors demonstrated that, when physiologically active substances were directly administered into submucous tissues without using a carrier, the physiologically active substances were effectively and safely retained at the administration sites over long periods without loss and diffusion, and produced the effect acting in a reservoir-like fashion. The physiologically active substances administered as described above were demonstrated to produce the therapeutic effect without having an influence on organs other than the administered organ.
