Although adult neurogenesis can also be modulated by neuronal activity before synaptogenesis, how distinct exercises contribute to the neurological reorganization of the injured cerebral cortex remains unclear. In the present study, we aimed to elucidate the effects of different exercise therapies on motor recovery and neuronal reorganization after photochemically induced focal cerebral infarction.\nMethods: Here, we examined the effects of three different exercises-(a) forced lower-intensity and (b) higher-intensity treadmill exercises, and (c) voluntary exercise with wheel running-on motor recovery and adult neurogenesis in a rat model of focal cerebral infarction. Photochemically induced thrombosis (PIT) was used to generate focal infarction in rats that was mostly confined to their motor cortices.\nResults: Beam walking tests showed that recovery after PIT-induced cortical infarction differed in acute and chronic stages and was influenced by the type of exercise. Furthermore, forced low-intensity training had more positive effects on functional recovery than other exercises or control. To evaluate the production of newly generated cells including de novo neurogenesis, we performed lineage analysis with BrdU labeling and immunofluorescence experiments. Lower-intensity treadmill exercise increased the number of BrdU/NeuN colabeled cells, but not total BrdU-retaining or BrdU/Sox2-colabeled cells, in the peri-infarct region of the ipsilateral cortex. In contrast, high-intensity treadmill or voluntary exercises had the opposite effects.\nConclusions: These results suggest that neuronal maturation can be differently modulated by distinct exercises and that low-intensity treadmill exercise could result in more potent generation of mature neurons. This also suggests the possibility that the generation of neural stem/progenitor cells and differentiation might be modulated by rehabilitation-mediated neural plasticity.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_5_dissertation_number_18":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第824号"}]},"item_5_publisher_6":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"John Wiley & Sons","subitem_publisher_language":"en"}]},"item_5_relation_26":{"attribute_name":"PubMed番号","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"31989796","subitem_relation_type_select":"PMID"}}]},"item_5_relation_28":{"attribute_name":"出版社DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1002/brb3.1535 ","subitem_relation_type_select":"DOI"}}]},"item_5_source_id_20":{"attribute_name":"EISSN","attribute_value_mlt":[{"subitem_source_identifier":"2162-3279","subitem_source_identifier_type":"EISSN"}]},"item_5_version_type_32":{"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_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":"森下, 紗帆","creatorNameLang":"ja"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-04-30"}],"displaytype":"detail","filename":"DT_824ronbun.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"論文本文","objectType":"fulltext","url":"https://hama-med.repo.nii.ac.jp/record/3591/files/DT_824ronbun.pdf"},"version_id":"969c7f69-db4c-44a0-a458-bdbc76250b72"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"cerebral infarction","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"differentiation/maturation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"exercise","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"neurogenesis.","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"Different exercises can modulate the differentiation/maturation of neural stem/progenitor cells after photochemically induced focal cerebral infarction","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Different exercises can modulate the differentiation/maturation of neural stem/progenitor cells after photochemically induced focal cerebral infarction","subitem_title_language":"en"}]},"item_type_id":"5","owner":"4","path":["17"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2020-04-30"},"publish_date":"2020-04-30","publish_status":"0","recid":"3591","relation_version_is_last":true,"title":["Different exercises can modulate the differentiation/maturation of neural stem/progenitor cells after photochemically induced focal cerebral infarction"],"weko_creator_id":"4","weko_shared_id":-1},"updated":"2023-10-17T03:04:57.630475+00:00"}
