This study was designed to elucidate the cellular and molecular basis of histone-induced lethality and to assess the protective effects of recombinant thrombomodulin (rTM). rTM has been approved for the treatment of disseminated intravascular coagulation (DIC) in Japan, and is currently undergoing a phase III clinical trial in the United States.\nMethods: Histone H3 levels in plasma of healthy volunteers and patients with sepsis and DIC were measured using enzyme-linked immunosorbent assay. Male C57BL/6 mice were injected intravenously with purified histones, and pathological examinations were performed. The protective effects of rTM against histone toxicity were analyzed both in vitro and in mice.\nResults: Histone H3 was not detectable in plasma of healthy volunteers, but significant levels were observed in patients with sepsis and DIC. These levels were higher in non-survivors than in survivors. Extracellular histones triggered platelet aggregation, leading to thrombotic occlusion of pulmonary capillaries and subsequent right-sided heart failure in mice. These mice displayed symptoms of DIC, including hrombocytopenia, prolonged prothrombin time, decreased fibrinogen, fibrin deposition in capillaries, and bleeding. Platelet depletion protected mice from histone-induced death in the first 30 minutes, suggesting that vessel occlusion by platelet-rich thrombi might be responsible for death during the early phase. Furthermore, rTM bound to extracellular histones, suppressed histoneinduced platelet aggregation, thrombotic occlusion of pulmonary capillaries, and dilatation of the right ventricle, and rescued mice from lethal thromboembolism.\nConclusions: Extracellular histones cause massive thromboembolism associated with consumptive coagulopathy, which is diagnostically indistinguishable from DIC. rTM binds to histones and neutralizes the prothrombotic action of histones. This may contribute to the effectiveness of rTM against DIC.", "subitem_description_type": "Other"}, {"subitem_description": "Mayumi Nakahara, Takashi Ito, Ko-ichi Kawahara, Mika Yamamoto, Tomoka Nagasato, Binita Shrestha, Shingo Yamada, Takahiro Miyauchi, Koji Higuchi, Toshihiro Takenaka, Tomotsugu Yasuda, Akira Matsunaga, Yasuyuki Kakihana, Teruto Hashiguchi, Yuichi Kanmura, Ikuro Maruyama\nRecombinant Thrombomodulin Protects Mice against Histone-Induced Lethal Thromboembolism\nPLoS ONE, 2013, 8(9), e75961\ndoi:10.1371/journal.pone.0075961", "subitem_description_type": "Other"}]}, "item_5_dissertation_number_55": {"attribute_name": "学位授与番号", "attribute_value_mlt": [{"subitem_dissertationnumber": "甲総研第281号"}]}, "item_5_full_name_2": {"attribute_name": "著者よみ", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "118586", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "ナカハラ, マユミ"}]}]}, "item_5_full_name_3": {"attribute_name": "別言語の著者", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "118587", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "NAKAHARA, Mayumi"}]}]}, "item_5_publisher_23": {"attribute_name": "公開者・出版者", "attribute_value_mlt": [{"subitem_publisher": "PLoS ONE"}, {"subitem_publisher": "鹿児島大学"}]}, "item_5_subject_15": {"attribute_name": "NDC", "attribute_value_mlt": [{"subitem_subject": "490", "subitem_subject_scheme": "NDC"}]}, "item_5_text_24": {"attribute_name": "公開者よみ", "attribute_value_mlt": [{"subitem_text_value": "カゴシマ ダイガク"}]}, "item_5_text_25": {"attribute_name": "公開者別名", "attribute_value_mlt": [{"subitem_text_value": "Kagoshima University"}]}, "item_5_text_30": {"attribute_name": "NIIタイプ", "attribute_value_mlt": [{"subitem_text_value": "Thesis or Dissertation"}]}, "item_5_text_44": {"attribute_name": "備考", "attribute_value_mlt": [{"subitem_text_value": "【指導教員:上村裕一】"}]}, "item_5_text_47": {"attribute_name": "date.appl", "attribute_value_mlt": [{"subitem_text_value": "【学位申請日】2014-02-05"}]}, "item_5_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_access_right": {"attribute_name": "アクセス権", "attribute_value_mlt": [{"subitem_access_right": "open access", "subitem_access_right_uri": "http://purl.org/coar/access_right/c_abf2"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "中原, 真由美"}], "nameIdentifiers": [{"nameIdentifier": "124229", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2016-10-31"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "Diss_中原_真由美_ISK281_2014.pdf", "filesize": [{"value": "2.6 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 2600000.0, "url": {"label": "Diss_中原_真由美_ISK281_2014.pdf", "url": "https://ir.kagoshima-u.ac.jp/record/12055/files/Diss_中原_真由美_ISK281_2014.pdf"}, "version_id": "415573eb-b8e6-4914-8e90-4f891b5f9407"}, {"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2016-10-31"}], "displaytype": "detail", "download_preview_message": "", "file_order": 1, "filename": "Abstract_中原_真由美_4509810174_2014.pdf", "filesize": [{"value": "73.9 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 73900.0, "url": {"label": "Abstract_中原_真由美_4509810174_2014.pdf", "url": "https://ir.kagoshima-u.ac.jp/record/12055/files/Abstract_中原_真由美_4509810174_2014.pdf"}, "version_id": "f3551f31-04d1-4894-956f-8fcb5cf2b8d8"}]}, "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": "doctoral thesis", "resourceuri": "http://purl.org/coar/resource_type/c_db06"}]}, "item_title": "Recombinant thrombomodulin protects mice against histone-induced lethal thromboembolism", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Recombinant thrombomodulin protects mice against histone-induced lethal thromboembolism"}]}, "item_type_id": "5", "owner": "3", "path": ["86"], "permalink_uri": "http://hdl.handle.net/10232/25499", "pubdate": {"attribute_name": "公開日", "attribute_value": "2015-10-29"}, "publish_date": "2015-10-29", "publish_status": "0", "recid": "12055", "relation": {}, "relation_version_is_last": true, "title": ["Recombinant thrombomodulin protects mice against histone-induced lethal thromboembolism"], "weko_shared_id": 3}
