However, distant metastasis control is an important issue. Recently, the combination of radiotherapy and immunotherapy has attracted the attention. In immunotherapy, dendritic cells (DCs) play a pivotal role of antitumor immune system. However, the mechanisms underlying the combination therapy of DCs and radiotherapy were unclear. In the present study, we evaluated anti-metastatic effects of this combination therapy focused on the irradiation type and the route of DC administration using a mouse model. C3H/He mice bearing NR-S1 cells were locally treated with CIRT or PBRT using biologically equivalent doses. Subsequently, DCs were administrated intratumorally (IT) or intravenously (IV). IV and IT DC-administrations (IV-DC, IT-DC) combined with CIRT to local tumor, but not alone, significantly suppressed pulmonary metastasis, whereas combination of DCs with PBRT did not suppress metastasis in the examined dose. Additionally, the anti-metastatic effect was greater in IV-DC compared to IT-DC. The expression level of CD40 and IL-12 in DCs were significantly increased after co-culturing with CIRT treated NR-S1 cells. In addition, IV-administration of those co-cultured DCs significantly suppressed pulmonary metastasis. Furthermore, ecto-Calreticulin levels from CIRT treated NR-S1 cells significantly increased compared to those of PBRT treated tumor. Taken together, these results suggest that local CIRT combined with IV-DC augments an immunogenicity of the tumor cells by ecto-Calreticulin expression and the maturation of DCs to stimulate antitumor immunity to decrease lung metastases.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Oxford academic"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1093/jrr/rrx005","subitem_relation_type_select":"DOI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0449-3060","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"安藤, 謙"}],"nameIdentifiers":[{"nameIdentifier":"485612","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"藤田, 英俊"}],"nameIdentifiers":[{"nameIdentifier":"485613","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hosoi, Akihiko"}],"nameIdentifiers":[{"nameIdentifier":"485614","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"馬, 立秋"}],"nameIdentifiers":[{"nameIdentifier":"485615","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"若月, 優"}],"nameIdentifiers":[{"nameIdentifier":"485616","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Seino, Ken-ichiro"}],"nameIdentifiers":[{"nameIdentifier":"485617","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kakimi, Kazuhiro"}],"nameIdentifiers":[{"nameIdentifier":"485618","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"今井, 高志"}],"nameIdentifiers":[{"nameIdentifier":"485619","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"下川, 卓志"}],"nameIdentifiers":[{"nameIdentifier":"485620","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakano, Takashi"}],"nameIdentifiers":[{"nameIdentifier":"485621","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"安藤 謙","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"485622","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"藤田 英俊","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"485623","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"馬 立秋","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"485624","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"若月 優","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"485625","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"今井 高志","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"485626","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"下川 卓志","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"485627","nameIdentifierScheme":"WEKO"}]}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Intravenous dendritic cell-administration enhances suppression of lung metastasis induced by carbon-ion irradiation","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Intravenous dendritic cell-administration enhances suppression of lung metastasis induced by carbon-ion irradiation"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-08-21"},"publish_date":"2017-08-21","publish_status":"0","recid":"48319","relation_version_is_last":true,"title":["Intravenous dendritic cell-administration enhances suppression of lung metastasis induced by carbon-ion irradiation"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:29:28.072206+00:00"}
