We previously determined that FRb-macrophages in glioma may play a role to promote tumor growth. The present study evaluated the efficacy of targeting of FRb-macrophages by anti-FRb immunotoxin for treating immunotherapy of weakly immunogenic F98 glioma rat models. Fischer rats received an intracerebral  implantation of F98 cells. After 3 days, subcutaneous administration of vaccination (freeze/thaw treated F98) were performed in presence/absence of immunotoxin (intraperitoneal administration). However, no significant differences in survival times were observed. When combined liveing cell F98 and immunotoxin administration enhanced survival times, but significance was not observed. We investigated the presence of anti-immunotoxin antibodies. We further developed newly immunotoxin which showed low immunogenicity and used for long-term administration.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_8_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"鹿児島大学","subitem_publisher_language":"ja"},{"subitem_publisher":"Kagoshima University","subitem_publisher_language":"en"}]},"item_8_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"491","subitem_subject_scheme":"NDC"}]},"item_8_text_41":{"attribute_name":"科研費番号 ","attribute_value_mlt":[{"subitem_text_value":"23592134"}]},"item_8_version_type_14":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"永井, 拓","creatorNameLang":"ja"},{"creatorName":"NAGAI, Taku","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"15492","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000090363647","nameIdentifierScheme":"NRID","nameIdentifierURI":" "}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-27"}],"displaytype":"detail","filename":"23592134_永井拓.pdf","filesize":[{"value":"775.8 kB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"23592134_永井拓.pdf","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/3062/files/23592134_永井拓.pdf"},"version_id":"513807f3-e3e9-4a15-8f05-459f47af7cd5"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"マクロファージ","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"脳腫瘍","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"抗体医薬","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"イムノトキシン","subitem_subject_language":"ja","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"がん免疫回避に関わるマクロファージの機能解明とその制御法の確立","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"がん免疫回避に関わるマクロファージの機能解明とその制御法の確立","subitem_title_language":"ja"},{"subitem_title":"Characterization and targeting Folate receptor-beta expressed tumor associated macrophages in glioblastoma","subitem_title_language":"en"}]},"item_type_id":"8","owner":"18","path":["80"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2015-05-22"},"publish_date":"2015-05-22","publish_status":"0","recid":"3062","relation_version_is_last":true,"title":["がん免疫回避に関わるマクロファージの機能解明とその制御法の確立"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-05-24T00:23:56.266324+00:00"}
