Among HNSCCs, oropharynx squamous cell carcinoma (OSCC) has a unique profile and is associated with human papillomavirus infection. Recently, anti-programmed cell death-1 monoclonal antibody has yielded good clinical responses in recurrent and/or metastatic HNSCC patients. Therefore, programmed death-ligand 1 (PD-L1) may be a favorable target molecule for cancer immunotherapy. Although PD-L1-expressing malignant cells could be targeted by PD-L1-specific CD8+ cytotoxic T lymphocytes, it remains unclear whether CD4+ helper T lymphocytes (HTLs) recognize and kill tumor cells in a PD-L1-specific manner.\nMETHODS:\n\\nThe expression levels of PD-L1 and HLA-DR were evaluated using immunohistochemical analyses. MHC class II-binding peptides for PD-L1 were designed based on computer algorithm analyses and added into in vitro culture of HTLs with antigen-presenting cells to evaluate their stimulatory activity.\nRESULTS:\n\\nWe found that seven of 24 cases of OSCC showed positive for both PD-L1 and HLA-DR and that PD-L1241-265 peptide efficiently activates HTLs, which showed not only cytokine production but also cytotoxicity against tumor cells in a PD-L1-dependent manner. Also, an adoptive transfer of the PD-L1-specific HTLs significantly inhibited growth of PD-L1-expressing human tumor cell lines in an immunodeficient mouse model. Importantly, T cell responses specific for the PD-L1241-265 peptide were detected in the HNSCC patients.\nCONCLUSIONS:\n\\nThe cancer immunotherapy targeting PD-L1 as a helper T-cell antigen would be a rational strategy for HNSCC patients.","subitem_description_type":"Abstract"}]},"item_10_description_37":{"attribute_name":"item_10_description_37","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_10_description_41":{"attribute_name":"item_10_description_41","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_10_dissertation_number_29":{"attribute_name":"dissertation_number","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第538号"}]},"item_10_relation_24":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1186/s12967-019-1957-5.","subitem_relation_type_select":"DOI"}}]},"item_10_source_id_22":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"14795876","subitem_source_identifier_type":"PISSN"}]},"item_10_version_type_38":{"attribute_name":"出版タイプ","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":"野﨑, 結","creatorNameLang":"ja"},{"creatorName":"ノザキ, ユイ","creatorNameLang":"ja-Kana"},{"creatorName":"Nozaki, Yui","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"19380","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":"2020-01-07"}],"displaytype":"detail","filename":"7370.pdf","filesize":[{"value":"3.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"7370.pdf","objectType":"fulltext","url":"https://asahikawa-med.repo.nii.ac.jp/record/6175/files/7370.pdf"},"version_id":"48db3364-3749-426c-a17b-0283ef1e72b8"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Cancer immunotherapy","subitem_subject_scheme":"Other"},{"subitem_subject":"Head and neck squamous cell carcinoma","subitem_subject_scheme":"Other"},{"subitem_subject":"Helper T-cells","subitem_subject_scheme":"Other"},{"subitem_subject":"PD-L1","subitem_subject_scheme":"Other"},{"subitem_subject":"Tumor-associated antigen","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"item_resource_type","attribute_value_mlt":[{"resourcetype":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_title":"PD-L1-specific helper T-cells exhibit effective antitumor responses: new strategy of cancer immunotherapy targeting PD-L1 in head and neck squamous cell carcinoma.","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"PD-L1-specific helper T-cells exhibit effective antitumor responses: new strategy of cancer immunotherapy targeting PD-L1 in head and neck squamous cell carcinoma.","subitem_title_language":"en"}]},"item_type_id":"10","owner":"3","path":["41"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2020-01-07"},"publish_date":"2020-01-07","publish_status":"0","recid":"6175","relation_version_is_last":true,"title":["PD-L1-specific helper T-cells exhibit effective antitumor responses: new strategy of cancer immunotherapy targeting PD-L1 in head and neck squamous cell carcinoma."],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2025-01-15T05:47:33.022281+00:00"}
