We have previously established hybridoma clones producing anti-P mAbs. In this study, we explored the pathogenesis of behavioral disorders induced by anti-P Abs using these mAbs. New Zealand Black x New Zealand White F1, New Zealand White, C57BL/6, and BALB/c mice were treated with 1 mg of anti-P Abs once every 2 wk. The behavioral disorder was evaluated by the tail suspension test, forced swim test, and open field test. Following administration of anti-P Abs, New Zealand Black x New Zealand White F1 and C57BL/6 mice developed depressive behavior and showed increased anxiety with elevated serum TNF-α and IL-6 levels. Anti-P Abs were not deposited in the affected brain tissue; instead, this mood disorder was associated with lower serum and brain tryptophan concentrations. Tryptophan supplementation recovered serum tryptophan levels and prevented the behavioral disorder. TNF-α and IL-6 were essential for the decreased serum tryptophan and disease development, which were ameliorated by treatment with anti–TNF-α neutralizing Abs or dexamethasone. Peritoneal macrophages from C57BL/6 mice produced TNF-α, IL-6, and IDO-1 via interaction with anti-P Abs through activating FcγRs, which were required for disease development. IVIg, which has an immunosuppressive effect partly through the regulation of FcγR expression, also prevented the decrease in serum tryptophan and disease development. Furthermore, serum tryptophan concentrations were decreased in the sera of systemic lupus erythematosus patients with anti-P Abs, and lower tryptophan levels correlated with disease activity. Our study revealed some of the molecular mechanisms of mood disorder induced by anti-P Abs.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_6_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"Journal of immunology. 2021, 206(8), 1729-1739.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_6_description_53":{"attribute_name":"学位記番号","attribute_value_mlt":[{"subitem_description":"新大院博(医)第1025号","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_6_dissertation_number_52":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第4935号"}]},"item_6_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.4049/jimmunol.2000260","subitem_relation_type_select":"DOI"}}]},"item_6_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"【○!C】 2021 by TheAmericanAssociation of Immunologists, Inc.","subitem_rights_language":"en"}]},"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":"Cho, Takamasa","creatorNameLang":"en"},{"creatorName":"張, 高正","creatorNameLang":"ja"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"date":[{"dateType":"Available","dateValue":"2022-05-10"}],"displaytype":"detail","filename":"r3nmk1025.pdf","filesize":[{"value":"2.29MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"本文","objectType":"fulltext","url":"https://niigata-u.repo.nii.ac.jp/record/2000467/files/r3nmk1025.pdf"},"version_id":"5712967b-7d84-4d31-8fb5-1a0b13430465"},{"date":[{"dateType":"Available","dateValue":"2022-05-10"}],"displaytype":"detail","filename":"r3nmk1025_a.pdf","filesize":[{"value":"440KB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"要旨","objectType":"abstract","url":"https://niigata-u.repo.nii.ac.jp/record/2000467/files/r3nmk1025_a.pdf"},"version_id":"910028e1-4a97-4dbe-bc7e-a28d5a13cc7d"}]},"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":"Mood Disorder in Systemic Lupus Erythematosus Induced by Antiribosomal P Protein Antibodies Associated with Decreased Serum and Brain Tryptophan","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Mood Disorder in Systemic Lupus Erythematosus Induced by Antiribosomal P Protein Antibodies Associated with Decreased Serum and Brain Tryptophan","subitem_title_language":"en"},{"subitem_title":"抗P抗体はSLEにおいて血中・脳中トリプトファンの低下を介して気分障害を引き起こす","subitem_title_language":"ja"}]},"item_type_id":"6","owner":"1","path":["455","562"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2022-05-10"},"publish_date":"2022-05-10","publish_status":"0","recid":"2000467","relation_version_is_last":true,"title":["Mood Disorder in Systemic Lupus Erythematosus Induced by Antiribosomal P Protein Antibodies Associated with Decreased Serum and Brain Tryptophan"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-15T04:16:56.132139+00:00"}
