Here, we examined this effect. Transendothelial electrical resistance (TEER) of in vitro BBB model, was significantly dose dependently decreased by CNP. CNP treatment reduced both the messenger RNA and protein expressions of zonula occludens-1  (Z0-1). The effects on TEER, mRNA, and protein expressions of ZO-1 were mimicked by cyclic GMP (cGMP) analog 8-bromo-cGMP and reversed by protein kinase G (PKG) inhibitor Rp-8-CPT-cGMPS, thus implying the role of PKG and cGMP signaling in BBB function. In vivo study of mouse brain by fluorimetric analysis with intravenous administration of sodium fluorescein also showed a significant increase in BBB permeability by CNP. These findings suggest that CNP modulates the BBB permeability by altering ZO-1.", "subitem_description_type": "Other"}]}, "item_8_full_name_2": {"attribute_name": "著者よみ", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "117943", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "ナガヤマ, テツヤ"}]}]}, "item_8_full_name_3": {"attribute_name": "別言語の著者", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "117944", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "NAGAYAMA, Tetsuya"}]}]}, "item_8_publisher_23": {"attribute_name": "公開者・出版者", "attribute_value_mlt": [{"subitem_publisher": "鹿児島大学"}]}, "item_8_subject_15": {"attribute_name": "NDC", "attribute_value_mlt": [{"subitem_subject": "493", "subitem_subject_scheme": "NDC"}]}, "item_8_text_24": {"attribute_name": "公開者よみ", "attribute_value_mlt": [{"subitem_text_value": "カゴシマ ダイガク"}]}, "item_8_text_25": {"attribute_name": "公開者別名", "attribute_value_mlt": [{"subitem_text_value": "Kagoshima University"}]}, "item_8_text_30": {"attribute_name": "NIIタイプ", "attribute_value_mlt": [{"subitem_text_value": "Research Paper"}]}, "item_8_text_41": {"attribute_name": "科研費番号 ", "attribute_value_mlt": [{"subitem_text_value": "23592100"}]}, "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": "永山, 哲也"}], "nameIdentifiers": [{"nameIdentifier": "29271", "nameIdentifierScheme": "WEKO"}, {"nameIdentifier": "1000040336334", "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": "2016-10-28"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "23592100_永山哲也.pdf", "filesize": [{"value": "349.8 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 349800.0, "url": {"label": "23592100_永山哲也.pdf", "url": "https://ir.kagoshima-u.ac.jp/record/6008/files/23592100_永山哲也.pdf"}, "version_id": "7112c763-d074-4606-94bc-f5d9835dec59"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "血液脳関門", "subitem_subject_scheme": "Other"}, {"subitem_subject": "C型ナトリウム利尿ペプチド", "subitem_subject_scheme": "Other"}, {"subitem_subject": "zonula occludens-1", "subitem_subject_scheme": "Other"}, {"subitem_subject": "JunD", "subitem_subject_scheme": "Other"}, {"subitem_subject": "ドラッグデリバリーシステム", "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": "脳卒中におけるCNPの病態生理学的意義の解明", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "脳卒中におけるCNPの病態生理学的意義の解明"}]}, "item_type_id": "8", "owner": "3", "path": ["80"], "permalink_uri": "http://hdl.handle.net/10232/24141", "pubdate": {"attribute_name": "公開日", "attribute_value": "2015-05-22"}, "publish_date": "2015-05-22", "publish_status": "0", "recid": "6008", "relation": {}, "relation_version_is_last": true, "title": ["脳卒中におけるCNPの病態生理学的意義の解明"], "weko_shared_id": 3}
