摘要:
A human antibody that has a specific reactivity with multiple tumor cell lines including ATL cells and possesses both safety and therapeutic efficacy and a fragment of said antibody are provided. A human antibody and a fragment of said antibody that may recognize HLA-DR β chain expressed on the surface of tumor cells were obtained. In particular, it was found that a dimer of scFv (diabody) of said antibody may induce potent apoptosis in cells expressing the HLA-DR β chain. The antibody and a fragment of said antibody obtained in accordance with the present invention are useful for a detection reagent, a diagnostic and a medicament for protection or treatment of cancers including ATL and/or viral infectious diseases.
