In this study, we analyzed roles of B cell-intrinsic TLR7 signaling on humoral immune responses against retrovirus infection. We found that primary B cell responses to retroviral infection required B cell-intrinsic TLR7 signaling, whereas preexisting virus-specific memory Th cells elicited the B cell responses without TLR7 signaling. Moreover, we showed that in the presence of virus-specific memory Th cells, the lack of TLR7 signaling in B cells facilitated anti-virus antibody responses and led to delayed progression of virus-induced leukemia.","subitem_description_type":"Abstract"}]},"item_8_description_36":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究種目:基盤研究(C); 研究期間:2013~2015; 課題番号:25460507; 研究分野:感染制御; 科研費の分科・細目:","subitem_description_type":"Other"}]},"item_8_description_37":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Research Paper","subitem_description_type":"Other"}]},"item_8_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_8_publisher_14":{"attribute_name":"出版者 名前","attribute_value_mlt":[{"subitem_publisher":"近畿大学"}]},"item_8_relation_11":{"attribute_name":"著者 外部リンク","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-25460507/"}]}]},"item_8_text_10":{"attribute_name":"著者 役割","attribute_value_mlt":[{"subitem_text_value":"研究代表者"},{"subitem_text_value":"研究分担者"},{"subitem_text_value":"研究分担者"}]},"item_8_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"KAWAHARA, Sachiyo"},{"subitem_text_language":"en","subitem_text_value":"MIYAZAWA, Masaaki"},{"subitem_text_language":"en","subitem_text_value":"TAKAMURA, Shiki"}]},"item_8_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学医学部; 講師"},{"subitem_text_value":"近畿大学医学部; 教授"},{"subitem_text_value":"近畿大学医学部; 講師"}]},"item_8_text_9":{"attribute_name":"著者所属(翻訳)","attribute_value_mlt":[{"subitem_text_value":"Kindai University"}]},"item_8_version_type_12":{"attribute_name":"版","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_be7fb7dd8ff6fe43","subitem_version_type":"NA"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"河原, 佐智代"},{"creatorName":"カワハラ, サチヨ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"宮澤, 正顯"},{"creatorName":"ミヤザワ, マサアキ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"高村, 史記"},{"creatorName":"タカムラ, シキ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-14"}],"displaytype":"detail","filename":"25460507seika.pdf","filesize":[{"value":"171.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"25460507seika.pdf","url":"https://kindai.repo.nii.ac.jp/record/18113/files/25460507seika.pdf"},"version_id":"fe2ab65b-7bdc-4d4e-8b57-cbb4586b32a3"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"レトロウイルス","subitem_subject_scheme":"Other"},{"subitem_subject":"TLR7","subitem_subject_scheme":"Other"},{"subitem_subject":"B細胞","subitem_subject_scheme":"Other"},{"subitem_subject":"免疫回避","subitem_subject_scheme":"Other"},{"subitem_subject":"ウイルス中和抗体","subitem_subject_scheme":"Other"},{"subitem_subject":"白血病","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":"レトロウイルスのToll様受容体を利用した免疫回避機構の解明","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"レトロウイルスのToll様受容体を利用した免疫回避機構の解明"},{"subitem_title":"Retroviral immune evasion","subitem_title_language":"en"}]},"item_type_id":"8","owner":"29","path":["4296"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-10-14"},"publish_date":"2016-10-14","publish_status":"0","recid":"18113","relation_version_is_last":true,"title":["レトロウイルスのToll様受容体を利用した免疫回避機構の解明"],"weko_creator_id":"29","weko_shared_id":-1},"updated":"2023-06-20T22:08:07.728757+00:00"}
