Moreover TM also bounds PAMPs(Pathogen Associated Molecular Patterns) ;lipopolysaccaride(LPS), a representative PAMPs, onto the lectin-like domain of the molecule and neutralizes their cytopathic activities, including proinflammatory and procoagulant activities. HMGB1 bound to TM, degraded by thrombin/TM complex and generated the N-terminus deleted HMGB1, named as des-HMGB1. Des-HMGB1 bound onto the receptors RAGE and TLR2-2, -4. However the binding affinity was weak compared to intact HMGB1, suggesting des-form of the molecule may configure a negative feedback loop among HMGB1 and its receptors regulating the diverse activities of HMGB1. Based on the findings, assay of des-HMGB1.may provide significant information in such morbid states including Disseminated Intravascular Coagulation(DIC), sepsis, systemic inflammatory response sybdrome(SIRS) and so on. Therefore we tried to establish specific assay method of des-HMGB1. We got specific monoclonal antibodies to react with the des-HMGB1. Using the monoclonal antibody, we established specific enzyme linked immune sorbent assay(ELISA). The ELISA successfully detected des-HMGB1 with 10% contamination of intact form. Des-HMGB1 was increased the serum from DIC, especially treated with recombinant TM. However the increased des-HMGB1 was decreased rapidly suggesting the rapid turn-over of the des-form. Moreover some patients showed no increased in des-HMGB1 even with recombinant TM treatment, suggesting of the presence or non-responder cases. Thus assessment of des-HMGB1 may be expected to provide a novel information in the DIC, SIRS, sepsis and so on with or without treatment.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_8_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"鹿児島大学","subitem_publisher_language":"ja"},{"subitem_publisher":"Kagoshima University","subitem_publisher_language":"en"}]},"item_8_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"494.27","subitem_subject_scheme":"NDC"}]},"item_8_text_41":{"attribute_name":"科研費番号 ","attribute_value_mlt":[{"subitem_text_value":"24659798"}]},"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":"丸山, 征郎","creatorNameLang":"ja"},{"creatorName":"MARUYAMA, Ikuro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"6517","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000020082282","nameIdentifierScheme":"NRID","nameIdentifierURI":" "}]},{"creatorNames":[{"creatorName":"伊藤, 隆史","creatorNameLang":"ja"},{"creatorName":"ITO, Takashi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"6518","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000020381171","nameIdentifierScheme":"NRID","nameIdentifierURI":" "}]},{"creatorNames":[{"creatorName":"橋口, 照人","creatorNameLang":"ja"},{"creatorName":"HASHIGUCHI, Teruto","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"6519","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000070250917","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":"2016-10-27"}],"displaytype":"detail","filename":"24659798.pdf","filesize":[{"value":"180.7 kB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"24659798.pdf","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/1029/files/24659798.pdf"},"version_id":"5eb9e38d-a8ec-4a56-845f-7b5329783c14"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"PAMPs","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"DAMPs","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"トロンボモジュリン","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"プロテインC","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"HMGB1","subitem_subject_language":"en","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":"Pamps-DAMPsの包括的制御システムとしてのTM-PC/EPCR装置","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Pamps-DAMPsの包括的制御システムとしてのTM-PC/EPCR装置","subitem_title_language":"ja"},{"subitem_title":"Comprehensive regulatory system of PAMPs/DAMPs by TM-PC/EPCR system","subitem_title_language":"en"}]},"item_type_id":"8","owner":"18","path":["80"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2013-10-01"},"publish_date":"2013-10-01","publish_status":"0","recid":"1029","relation_version_is_last":true,"title":["Pamps-DAMPsの包括的制御システムとしてのTM-PC/EPCR装置"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-05-24T00:24:10.631768+00:00"}
