Previous studies have reported contrasting results regarding the abilities of exosomes circulating in the blood of sepsis mice and patients to either promote or suppress inflammation. Little is known about how the gut epithelial cell-derived exosomes released in the intestinal luminal space during sepsis affect mucosal inflammation. To study this question, we isolated extracellular vesicles (EVs) from intestinal lavage of septic mice. The EVs expressed typical exosomal (CD63 and CD9) and epithelial (EpCAM) markers, which were further increased by sepsis. Moreover, septic-EV injection into inflamed gut induced a significant reduction in the messaging of pro-inflammatory cytokines TNF-a and IL-17A. MicroRNA (miRNA) profiling and reverse transcription and quantitative polymerase chain reaction (RT-qPCR) revealed a sepsis-induced exosomal increase in multiple miRNAs, which putatively target TNF-a and IL-17A. These results imply that intestinal epithelial cell (IEC)-derived luminal EVs carry miRNAs that mitigate pro-inflammatory responses. Taken together, our study proposes a novel mechanism by which IEC EVs released during sepsis transfer regulatory miRNAs to cells, possibly contributing to the amelioration of gut inflammation.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_7_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"本文/Department of Molecular Pathobiology and Cell Adhesion Biology, Mie University Graduate School of Medicine, Tsu, Mie 514-8507, Japan","subitem_description_type":"Other"},{"subitem_description":"44p","subitem_description_type":"Other"}]},"item_7_dissertation_number_60":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲医学第2083号"}]},"item_7_full_name_2":{"attribute_name":"著者（ヨミ）","attribute_value_mlt":[{"names":[{"name":"アピア, マイケル ギャシ","nameLang":"ja"}]}]},"item_7_publisher_30":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"三重大学"}]},"item_7_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.3390/ijms21228445","subitem_relation_type_select":"DOI"}}]},"item_7_text_31":{"attribute_name":"出版者（ヨミ）","attribute_value_mlt":[{"subitem_text_value":"ミエダイガク"}]},"item_7_text_63":{"attribute_name":"ノート","attribute_value_mlt":[{"subitem_text_value":"International Journal of Molecular Sciences, 2020, 21, 8445に掲載"}]},"item_7_text_65":{"attribute_name":"資源タイプ（三重大）","attribute_value_mlt":[{"subitem_text_value":"Doctoral Dissertation / 博士論文"}]},"item_7_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_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":"Appiah, Michael Gyasi","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-01-04"}],"displaytype":"detail","filename":"2021DM0904.pdf","filesize":[{"value":"2.4 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"2021DM0904","objectType":"fulltext","url":"https://mie-u.repo.nii.ac.jp/record/14450/files/2021DM0904.pdf"},"version_id":"b0193c1e-0e12-40fd-ba2e-3a459b0cf883"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"sepsis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"intestinal epithelial cells","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"inflammation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"extracellular vesicles","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"TNF-α","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"IL-17A","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"miRNAs","subitem_subject_language":"en","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":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_title":"Intestinal Epithelium-Derived Luminally Released Extracellular Vesicles in Sepsis Exhibit the Ability to Suppress TNF-α and IL-17A Expression in Mucosal Inflammation","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Intestinal Epithelium-Derived Luminally Released Extracellular Vesicles in Sepsis Exhibit the Ability to Suppress TNF-α and IL-17A Expression in Mucosal Inflammation","subitem_title_language":"en"}]},"item_type_id":"7","owner":"16","path":["1308"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2022-01-04"},"publish_date":"2022-01-04","publish_status":"0","recid":"14450","relation_version_is_last":true,"title":["Intestinal Epithelium-Derived Luminally Released Extracellular Vesicles in Sepsis Exhibit the Ability to Suppress TNF-α and IL-17A Expression in Mucosal Inflammation"],"weko_creator_id":"16","weko_shared_id":-1},"updated":"2023-10-17T02:03:19.183262+00:00"}
