Immunogold particles for these subunits<br />were accumulated over clusters of intramembrane particles(IMP) on the protoplasmic<br />face(P-face) of the plasma membrane, indicating that many IMP clusters of a certain<br />size represent GABAergic synapses.<br />The sizes of labelled synapses were not different on the somata and the main apical<br />dendritic trunks.However,the synaptic areas on AISs were significantly smaller than<br />those on the soma and apical dendrites. Axon initial segments were identified by<br />immunogold Labelling for the Nav1.6 subunit of sodium channels. The synaptic<br />receptor labelling densities for GABA-A receptor subunits were not significantly<br />different on the tested areas of the cells. A high proportion of receptor labelling was on<br />the extrasynaptic membrane of the pyramidal cell soma and dendrites. To examine the<br />co-localization of different GABA-A receptor subunits in single synapses on the soma,<br />double labelling was performed with antibodies raised in different species. These<br />experiments showed that the majority of synapses contains alpha1,alpha2,and beta2/3<br />subunits. Future experiments aim at testing whether distinct synapese populations<br />differing in the relative proportions of different subunits can be detected with freeze<br />fracture replica immunogold labelling.","subitem_description_type":"Other"}]},"item_1_description_18":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_1_description_7":{"attribute_name":"学位記番号","attribute_value_mlt":[{"subitem_description":"総研大甲第963号","subitem_description_type":"Other"}]},"item_1_select_14":{"attribute_name":"所蔵","attribute_value_mlt":[{"subitem_select_item":"有"}]},"item_1_select_8":{"attribute_name":"研究科","attribute_value_mlt":[{"subitem_select_item":"生命科学研究科"}]},"item_1_select_9":{"attribute_name":"専攻","attribute_value_mlt":[{"subitem_select_item":"20 生理科学専攻"}]},"item_1_text_10":{"attribute_name":"学位授与年度","attribute_value_mlt":[{"subitem_text_value":"2005"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"KASUGAI, Yu","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":"2016-02-17"}],"displaytype":"simple","filename":"甲963_要旨.pdf","filesize":[{"value":"168.8 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"要旨・審査要旨","url":"https://ir.soken.ac.jp/record/1165/files/甲963_要旨.pdf"},"version_id":"7c8354d3-9558-4422-8af2-05bc4f91b1d5"},{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-17"}],"displaytype":"simple","filename":"甲963_本文.pdf","filesize":[{"value":"18.0 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"本文","url":"https://ir.soken.ac.jp/record/1165/files/甲963_本文.pdf"},"version_id":"73188eb8-28c8-4fb0-b625-0f1fd2e284d0"}]},"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":"thesis","resourceuri":"http://purl.org/coar/resource_type/c_46ec"}]},"item_title":"Quantitative localization of GABAA receptor subunits on hippocampal pyramidal cells by SDS-digested freeze  fracture replica labeling(SDS-FRL)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Quantitative localization of GABAA receptor subunits on hippocampal pyramidal cells by SDS-digested freeze  fracture replica labeling(SDS-FRL)"},{"subitem_title":"Quantitative localization of GABAA receptor subunits on hippocampal pyramidal cells by SDS-digested freeze  fracture replica labeling(SDS-FRL)","subitem_title_language":"en"}]},"item_type_id":"1","owner":"1","path":["22"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-02-22"},"publish_date":"2010-02-22","publish_status":"0","recid":"1165","relation_version_is_last":true,"title":["Quantitative localization of GABAA receptor subunits on hippocampal pyramidal cells by SDS-digested freeze  fracture replica labeling(SDS-FRL)"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T16:07:47.559333+00:00"}
