Many studies have defined phenotypes of reactive microglia, the brain-resident macrophages, with different antigenic markers to identify those potentially causing inflammatory damage. We took an alternative approach with the goal of characterizing the distribution of purinergic receptor P2RY12-positive microglia, a marker previously defined as identifying homeostatic or non-activated microglia. We examined the expression of P2RY12 by dual-color light and fluorescence immunohistochemistry using sections of middle temporal gyrus from AD, high plaque and low plaque non-demented cases in relation to amyloid beta (Aβ) plaques and phosphorylated tau, markers of pathology, and HLA-DR, IBA-1, CD68, and progranulin, microglial phenotype markers. In low plaque cases, P2RY12-positive microglia mostly had non-activated morphologies, while the morphologies of P2RY12-positive microglia in AD brains were highly variable, suggesting its expression could encompass a wider range of phenotypes than originally hypothesized. P2RY12 expression by microglia differed depending on the types of plaques or tangles they were associated with. Areas of inflammation characterized by lack of P2RY12-positive microglia around mature plaques could be observed, but many diffuse plaques showed colocalization with P2RY12-positive microglia. Based on these results, P2RY12 expression by microglia should not be considered solely a marker of resting microglia as P2RY12 immunoreactivity was identifying microglia positive for CD68, progranulin and to a limited extent HLA-DR, markers of activation.","subitem_description_type":"Abstract"}]},"item_4_description_42":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Journal Article","subitem_description_type":"Other"}]},"item_4_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"MDPI AG"}]},"item_4_relation_10":{"attribute_name":"PubMed番号","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"31968618","subitem_relation_type_select":"PMID"}}]},"item_4_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.3390/ijms21020678"}],"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.3390/ijms21020678","subitem_relation_type_select":"DOI"}}]},"item_4_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"2020 by the authors."},{"subitem_rights":"This article is an open access article distributed under the terms and conditions of the Creative Commons Attribution (CC BY) license (http://creativecommons.org/licenses/by/4.0/)."}]},"item_4_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1422-0067","subitem_source_identifier_type":"ISSN"}]},"item_4_version_type_15":{"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":"WALKER, Douglas Gordon"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"TANG, Tiffany M"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MENDSAIKHAN, Anarmaa"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TOOYAMA, Ikuo"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"SERRANO, Geidy E"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SUE, Lucia I"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"BEARCH, Thomas G"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"LUE, Lih-Fen"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-02-05"}],"displaytype":"detail","filename":"ijms21020678.pdf","filesize":[{"value":"5.3 MB"}],"format":"application/pdf","license_note":"© 2020 by the authors.
