However, the widely used current ZnT8A radioligand binding assay (RBA) has proved to be difficult for many laboratories to implement. The aim of this study was the development and characterization of the performance of a novel fluid-phase ZnT8A enzyme-linked immunosorbent assay (ELISA) in relation to standard RBA in type 1 diabetes. Sera from 114 patients with type 1 diabetes and 140 blinded Islet Autoantibody Standardization Program (IASP2012) samples were studied. The sensitivity of ELISA-ZnT8A is equivalent to or slightly higher than that of conventional RBA with similar specificity. Furthermore, the median SD score using this ELISA was significantly higher than that obtained with RBA (P < 0.0001). Multiple logistic regression analysis revealed that ELISA-ZnT8A positivity was associated with younger age of onset (?20 years; OR 15.91, P = 0.0002), acute-onset form of type 1 diabetes (OR 3.38, P = 0.019), and the presence of IA-2 autoantibodies (OR 3.75, P = 0.014). Furthermore, the levels of ELISA-ZnT8A were associated with the reactivity to ZnT8-325Arg, but not ZnT8-325Trp. We conclude that this nonradioactive bivalent ZnT8A assay has high performance and should facilitate large-scale autoantibody screening. Moreover, these results suggest that the humoral autoimmunity against ZnT8 is related to a high risk of faster development of type 1 diabetes and the ZnT8A levels are associated with the known aa325 variants.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"Acta Diabetologica, 51(3), pp,429-434; 2014","subitem_description_type":"Other"}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Springer-Verlag Italia"}]},"item_2_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1007/s00592-013-0532-4","subitem_relation_type_select":"DOI"}}]},"item_2_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"c Springer-Verlag 2013."},{"subitem_rights":"The final publication is available at link.springer.com"}]},"item_2_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09405429","subitem_source_identifier_type":"ISSN"}]},"item_2_source_id_8":{"attribute_name":"EISSN","attribute_value_mlt":[{"subitem_source_identifier":"14325233","subitem_source_identifier_type":"ISSN"}]},"item_2_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Kawasaki, Eiji"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tanaka, Megumi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Miwa, Masaki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Abiru, Norio"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kawakami, Atsushi"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-21"}],"displaytype":"detail","filename":"ActDia51_429.pdf","filesize":[{"value":"189.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ActDia51_429.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/5678/files/ActDia51_429.pdf"},"version_id":"730e6fc6-32bf-4ac3-aefd-d1859ccc99b4"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Autoantibodies","subitem_subject_scheme":"Other"},{"subitem_subject":"ELISA","subitem_subject_scheme":"Other"},{"subitem_subject":"Radioimmunoassay","subitem_subject_scheme":"Other"},{"subitem_subject":"Type 1 diabetes","subitem_subject_scheme":"Other"},{"subitem_subject":"Zinc transporter 8","subitem_subject_scheme":"Other"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Novel enzyme-linked immunosorbent assay for bivalent ZnT8 autoantibodies","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Novel enzyme-linked immunosorbent assay for bivalent ZnT8 autoantibodies"}]},"item_type_id":"2","owner":"2","path":["11"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-07-01"},"publish_date":"2015-07-01","publish_status":"0","recid":"5678","relation_version_is_last":true,"title":["Novel enzyme-linked immunosorbent assay for bivalent ZnT8 autoantibodies"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-16T03:00:54.999342+00:00"}
