Classical BD in adult rats is in large part due to immunopathogenic damage to the nervous system by blood-borne inflammatory cells. However, newborn rats inoculated with mouse-adapted BDV variant (CRNP5) develop severe neurological disease without encephalitis. Thus, it is suggested that rats infected with CRNP5 develop BD without immune response, and CRNP5 is directly and/or indirectly due to damage to the central nervous system. In order to gain a better understanding of immune responses contributions to BD outcomes, we studied the neuropathogenesis of BDV in athymic nude rats (rnu/rnu), naturally deficient in the T-lymphocyte system. Four-week old female nude rats were either inoculated intracranially with 2×10^3 FFU of rat-adapted prototype variant (CRP3) (n=7) or CRNP5 (n=7) or an equal volume of uninfected mouse brain material (n=7). All CRNP5-infected nude rats developed fatal neurological disease although all CRP3-infected rats survived to 7 week post inoculation without obvious neurological signs of disease. No evidence of inflammatory cell infiltration was observed in rats infected with CRP3 or CRNP5, but an intensive gliosis was present. The brains of CRNP5-infected rats showed severe neuronal degeneration in pyramidal neurons in hippocampus. These results suggest that the cellular immune response to virus infection contributes to BD outcome in CRP3-infected rats but CRNP5-infected rats.","subitem_description_type":"Other"}]},"item_12_description_2":{"attribute_name":"ページ属性","attribute_value_mlt":[{"subitem_description":"P(論文)","subitem_description_type":"Other"}]},"item_12_description_3":{"attribute_name":"記事種別","attribute_value_mlt":[{"subitem_description":"特集","subitem_description_type":"Other"}]},"item_12_description_34":{"attribute_name":"format","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_12_description_4":{"attribute_name":"Type","attribute_value_mlt":[{"subitem_description":"FEATURE ARTICLES","subitem_description_type":"Other"}]},"item_12_publisher_19":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"麻布大学"}]},"item_12_publisher_20":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"Azabu University"}]},"item_12_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1346-5880","subitem_source_identifier_type":"ISSN"}]},"item_12_source_id_23":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11561468","subitem_source_identifier_type":"NCID"}]},"item_12_text_10":{"attribute_name":"Author ID","attribute_value_mlt":[{"subitem_text_value":"-"},{"subitem_text_value":"000283"},{"subitem_text_value":"-"}]},"item_12_text_11":{"attribute_name":"所属機関","attribute_value_mlt":[{"subitem_text_value":"麻布大学獣医学部獣医学科獣医免疫学研究室"},{"subitem_text_value":"麻布大学獣医学部獣医学科栄養学研究室"},{"subitem_text_value":"麻布大学獣医学部獣医学科附属動物病院教員研究室"}]},"item_12_text_12":{"attribute_name":"Institution or Company","attribute_value_mlt":[{"subitem_text_value":"Laboratory of Veterinary Immunology, Azabu University School of Veterinary Medicine"},{"subitem_text_value":"Laboratory of Nutrition, Azabu University School of Veterinary Medicine"},{"subitem_text_value":"Laboratory of Veterinary Teaching Hospital, Azabu University School of Veterinary Medicine"}]},"item_12_text_9":{"attribute_name":"著者ID","attribute_value_mlt":[{"subitem_text_value":"-"},{"subitem_text_value":"000283"},{"subitem_text_value":"-"}]},"item_12_version_type_29":{"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_12_version_type_30":{"attribute_name":"text version","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"西野, 佳以"},{"creatorName":"ニシノ, ヨシイ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"斑目, 広郎"},{"creatorName":"マダラマ, ヒロオ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"舟場, 正幸"},{"creatorName":"フナバ, マサユキ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nishino, Yoshii","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Madarame, Hiroo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Funaba, Masayuki","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2006-01-01"}],"displaytype":"detail","filename":"bull_jau_vol13-14-218.pdf","filesize":[{"value":"371.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"bull_jau_vol13-14-218.pdf","url":"https://az.repo.nii.ac.jp/record/5149/files/bull_jau_vol13-14-218.pdf"},"version_id":"b41b92c4-efc2-4a80-bf57-6b660cd40fa2"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"ウイルス性神経障害における発症関連因子の研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ウイルス性神経障害における発症関連因子の研究"},{"subitem_title":"Study of factors associated with development of neurological disease on virus-induced central nervous system damage","subitem_title_language":"en"}]},"item_type_id":"12","owner":"4","path":["290","511"],"pubdate":{"attribute_name":"公開日","attribute_value":"2006-01-01"},"publish_date":"2006-01-01","publish_status":"0","recid":"5149","relation_version_is_last":true,"title":["ウイルス性神経障害における発症関連因子の研究"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-06-19T07:50:23.312531+00:00"}
