    摘要： An objective of the present invention is to facilitate the acquisition of antibody-producing cells that are infiltrating virus-infected cells, cancer cells, abnormal cells forming a benign hyperplasia, and the like, and to improve the efficiency of the production of antibodies as well as nucleic acids encoding them from the antibody-producing cells.The present inventors discovered that, when cancer tissues comprising infiltrating lymphocytes are transplanted into highly immunodeficient animals that do not have T cells, B cells, and NK cells and further exhibit a low IFN production ability, the differentiation and proliferation of infiltrating lymphocytes are unexpectedly promoted, and the number of plasma cells that produce antibodies recognizing cancer tissues increases dramatically, plasma cells can be separated easily, and antibodies or nucleic acids encoding them can be easily prepared from the plasma cells.

    摘要： The present invention discloses reshaped antibody to human medulloblastoma cells comprising: (A) an L chain comprising: (1) a human L chain C region, and (2) an L chain V region comprising human L chain FRs and L chain CDRs of mouse monoclonal antibody ONS-M21 to human medulloblastoma cells; and, (B) an H chain containing: (1) a human H chain C region, and (2) an H chain V region comprising human H chain FRs and H chain CDRs of mouse monoclonal antibody ONS-M21 to human medulloblastoma cells. Since the majority of this reshaped human antibody is derived from a human antibody and mouse CDRs have a low level of antigenicity, the reshaped human antibody of the present invention has a low level of antigenicity in humans, and is therefore expected to be useful as a therapeutic agent and diagnostic tool for brain tumors such as medulloblastoma which strongly express antigen that is recognized by this antibody.

    摘要： The present inventors used antibody engineering techniques to prepare functional antibodies that correspond to individual mutations in causative genes of diseases, and discovered that such antibodies enable the treatment of the diseases. Specifically, the inventors succeeded in preparing ligands, particularly minibodies, which have agonistic activity to receptors that have almost completely lost responsiveness to their natural ligands because of gene mutations (for example, a thrombopoietin (TPO) receptor whose reactivity to TPO has been markedly impaired), and which can transduce signals by interacting with these mutant receptors at levels comparable to normal.
