However, this therapy development is challenged by incomplete understanding of its action. Here, we sought to label CTLA4 with 64Cu, and to evaluate the in vivo potential of [64Cu]CTLA4 ([64Cu]1) as a novel PET tracer.\nMethod: [64Cu]1 was synthesized by labeling DOTA-CTLA4 with 64Cu. PET scans and biodistribution were performed at 24 h, 48 h after [64Cu]1 injection for immunocompetent C57BL/6 mice bearing B16F10 melanomas.\nResult: PET showed high uptake of radioactivity in the spleen and gut-associated lymphoid tissue at 24 h (3.44 % ID/g, 2.61 % ID/g), 48 h (3.47 % ID/g, 2.49 %ID/g) after [64Cu]1 injection. B16F10 tumors also showed high uptake at 24 h (4.25 % ID/g) and retention at 48 h (3.74 % ID/g) after administration. Biodistribution data supported the PET imaging.  \nConclusion: PET with [64Cu]1 permitted to noninvasively track and quantify in vivo action of anti-CTLA-4 mAb, which would be helpful for facilitating the development of anti-CTLA4 mAb immunotherapy.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"The12th asia Oceania Congress of Nuclear Medicine and Biology","subitem_description_type":"Other"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Jiang, Cuiping"}],"nameIdentifiers":[{"nameIdentifier":"654894","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Xie, Lin"}],"nameIdentifiers":[{"nameIdentifier":"654895","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hanyu, Masayuki"}],"nameIdentifiers":[{"nameIdentifier":"654896","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Zhang, Yiding"}],"nameIdentifiers":[{"nameIdentifier":"654897","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Azuma, Rikako"}],"nameIdentifiers":[{"nameIdentifier":"654898","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Suzuki, Hisashi"}],"nameIdentifiers":[{"nameIdentifier":"654899","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shimokawa, Takashi"}],"nameIdentifiers":[{"nameIdentifier":"654900","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Wakizaka, Hidekatsu"}],"nameIdentifiers":[{"nameIdentifier":"654901","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Zang, Shiming"}],"nameIdentifiers":[{"nameIdentifier":"654902","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Wang, Feng"}],"nameIdentifiers":[{"nameIdentifier":"654903","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Zhang, Ming-Rong"}],"nameIdentifiers":[{"nameIdentifier":"654904","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"謝 琳","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"654905","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"破入 正行","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"654906","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"張 一鼎","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"654907","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"東 梨佳子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"654908","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鈴木 寿","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"654909","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"下川 卓志","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"654910","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"脇坂 秀克","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"654911","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"張 明栄","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"654912","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"A novel PET radiotracer for visualizing in vivo action of immune checkpoint blocker anti-CTLA4 mAb ","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"A novel PET radiotracer for visualizing in vivo action of immune checkpoint blocker anti-CTLA4 mAb "}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-01-10"},"publish_date":"2018-01-10","publish_status":"0","recid":"66580","relation_version_is_last":true,"title":["A novel PET radiotracer for visualizing in vivo action of immune checkpoint blocker anti-CTLA4 mAb "],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:47:20.211614+00:00"}
