The auther examined microfilaments, intermediate filaments and microtubules by immunofluorescence technique and electron microscopic observation. Furthermore, distribution of microfilaments using heavy meromyosin (HMM) decoration method was observed. The results obtained were as follows 1 In response to secretory stimulation with isoproterenol (IPR) or carbachol (CCH), parotid acini revealed exocytotic secretion that lumen was dilated and the number of secretory granules had markedly decreased. 2 Immunohistochemistry showed that actin was localized in the granular pattern of staining with the cytoplasm. Microfilament stained with rhodamine-phalloidin, which binds selectively to polymerised actin filaments. Most of the microfilaments were localized beneath the apicalplasma membrane. Upon stimulation with isoproterenol (IPR), the number of individed rhodamme phalloidm positive small granules increased dramatically, indicating that the secretory granules was surounded by microfilaments after the fusion with luminal membrane. 3 Intermediate filaments were stained by immunofluorescent techique using antibodies against cytokeratin, while microtubles were stained with anti β-tubulm In acinar cells, the intermediate filaments exhibited a reticular distribution in the cytoplasm. The microtubules exhibited aradial distribution in cytoplasm of longitudially from the apical resion to the basal resion. At secretory phase, the distribution of intermediate filaments and microtubules in the acinar cells were almost the same as the resting phase. 4 Ultrastructurally, microfilaments were not detectable around the secretory granules which stored in the cytoplasm, but were observed around them whose membranes were continuous with th luminal plasma membrane during exocytosis. These results indicate that microfilaments are localized mainly underneath the luminal plasma membrane at the resting phase and act as blockade to exocytosis. At the secretory phase, microfilaments allow exocytosis by encerclmg the discharged secretory granule membranes, provide forces for the extrusion of the secretory products through the action of actm-myosin contractile system.","subitem_description_type":"Other"}]},"item_2_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN0008135X","subitem_source_identifier_type":"NCID"}]},"item_2_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"1st Department of Oral and Maxillofacial Surgery, School of Dentistry, HEALTH SCIENCES TINTVERSTTY OE HOKKAIDO"}]},"item_2_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_language":"ja","subitem_text_value":"北海道医療大学歯学部"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1996-12-31"}],"displaytype":"detail","filename":"KJ00000095488.pdf","filesize":[{"value":"3.0 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"<原著>ラット耳下腺腺房細胞の開口分泌過程における細胞骨格の形態学的研究","objectType":"fulltext","url":"https://hsuh.repo.nii.ac.jp/record/8218/files/KJ00000095488.pdf"},"version_id":"7c5de554-fa6b-468d-b850-4dbc618fdba7"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"microfilaments","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"exocytosis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"cytoskeleton","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"parotid acmar cells","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"<原著>ラット耳下腺腺房細胞の開口分泌過程における細胞骨格の形態学的研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"<原著>ラット耳下腺腺房細胞の開口分泌過程における細胞骨格の形態学的研究","subitem_title_language":"ja"},{"subitem_title":"<ORIGINAL ARTICLE>Morphological study on cytoskeleton in the exocytosis of the rat parotid acinar cells in vitro","subitem_title_language":"en"}]},"item_type_id":"2","owner":"17","path":["575"],"pubdate":{"attribute_name":"PubDate","attribute_value":"1996-12-31"},"publish_date":"1996-12-31","publish_status":"0","recid":"8218","relation_version_is_last":true,"title":["<原著>ラット耳下腺腺房細胞の開口分泌過程における細胞骨格の形態学的研究"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2024-02-08T07:35:25.385113+00:00"}
