--- abstract: "Normal and 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine(MPTP)-treated cats were used to examine changes in N-methyl-D-aspartate (NMDA) receptor function. In vivo microdialysis studies showed that NMDA-stimulated dopamine (DA) release was similar in the normal dorso-lateral and ventro-medial caudate nucleus. In symptomatic animals, NMDA-stimulated DA release was significantly decreased in both striatal regions. In symptomatic animals, NMDA-stimulated dopamine release was significantly decreased in both striatal regions. In recovered animals, the dorsal striatum and ventral striatum demonstrated an upregulation in NMDA-stimulated dopamine release compared to symptomatic animals. Receptor autoradiography showed no significant differences in NMDA receptor binding between normal, symptomatic, and recovered animals in the dorso-lateral caudate. NMDA receptor binding was, however, upregulated in the ventro-medial caudate of recovered animals. With Western analysis, NR1 and NR2A subunit levels in the dorso-lateral caudate were shown to decrease significantly in symptomatic animals compared to normal and then increase in recovered animals compared to symptomatic animals. In the ventro-medial caudate, NR1 and NR2A levels in the symptomatic group were significantly increased compared to normal and recovered groups. These data suggest that there may be recovery-induced changes in the functional regulation of the NMDA receptors in the striatum contributing to the behavioral recovery seen in this model.\n" altloc: [] chapter: ~ commentary: ~ commref: ~ confdates: ~ conference: ~ confloc: ~ contact_email: ~ creators_id: [] creators_name: - family: Desai given: Anup honourific: Dr. lineage: '' - family: Rothblat given: David honourific: Dr. lineage: '' - family: Schneider given: Jay honourific: Dr. lineage: '' date: 2001 date_type: published datestamp: 2006-08-01 department: ~ dir: disk0/00/00/50/06 edit_lock_since: ~ edit_lock_until: ~ edit_lock_user: ~ editors_id: [] editors_name: [] eprint_status: archive eprintid: 5006 fileinfo: /style/images/fileicons/application_pdf.png;/5006/1/NMDA_MPTPcat.pdf full_text_status: public importid: ~ institution: ~ isbn: ~ ispublished: unpub issn: ~ item_issues_comment: [] item_issues_count: 0 item_issues_description: [] item_issues_id: [] item_issues_reported_by: [] item_issues_resolved_by: [] item_issues_status: [] item_issues_timestamp: [] item_issues_type: [] keywords: NMDA receptor; NR1; NR2A; cat; autoradiography; protein; striatum; microdialysis; dopamine lastmod: 2011-03-11 08:56:32 latitude: ~ longitude: ~ metadata_visibility: show note: ~ number: ~ pagerange: ~ pubdom: TRUE publication: none publisher: ~ refereed: FALSE referencetext: ~ relation_type: [] relation_uri: [] reportno: ~ rev_number: 12 series: ~ source: ~ status_changed: 2007-09-12 17:06:09 subjects: - neuro-chem succeeds: ~ suggestions: 'If this is unpublished, why am I required to enter a journal name?' sword_depositor: ~ sword_slug: ~ thesistype: ~ title: Changes in Striatal N-methyl-D-aspartate (NMDA) Stimulation of Dopamine Release and Receptor Subunit Expression During Expression of and Recovery from MPTP-Induced Parkinsonism type: other userid: 6562 volume: ~
