Unter physiologischen Bedingungen haben diese Radikalspezies (wie z.B. das Superoxidradikalanion) eine wichtige Funktion bei der Abwehr von Krankheitserregern. Während akuter oder chronischer Entzündungsvorgänge kann es allerdings zu einer überhöhten Produktion dieser hochreaktiven Radikale kommen, die durch zelluläre Systeme nicht mehr entgiftet werden können. Dies führt zu einer groben Beeinträchtigung der zellulären Funktionen und kann im Tod der betroffenen Zellen resultieren. Dieses Szenario einer überhöhten Radikalproduktion scheint (wie bei vielen anderen Erkrankungen, darunter auch Atherosklerose) auch bei neurodegenerativen Erkrankungen (wie z.B. Morbus Alzheimer oder der amyelotrophen lateralen Sklerose) Gültigkeit zu haben. Durch die cerebrale Produktion von freien Radikalen können Neuronen geschädigt werden und somit die Gehirnfunktionen beeinträchtigen. Offenbar nimmt bei diesen Vorgängen eine ausreichende Versorgung des Gehirns mit alpha-Tocopherol (alpha-TocH), dem biologisch aktivstem Vertreter der VitaminE Familie, eine ganz zentrale Stellung ein. Eine Unterversorgung des Gehirns mit alpha-TocH führt zu charakteristischen und schweren neurologischen Störungen, die denen der Friedreich's Ataxie nahezu ident sind. Diese Befunde beweisen eindeutig, daß eine ausreichende Versorgung des Gehirns mit alpha-TocH für normale neurologische Funktionen von fundamentaler Bedeutung ist. Unabhängig davon ist es allerdings nicht klar, welche Mechanismen die Versorgung des Gehirns mit alpha-TocH über die Blut-Hirnschranke gewährleisten und ob alpha-TocH im Gehirn nur eine antioxidative (d.h. Entgiftung der oben angeführten Radikalspezies) oder andere, noch unbekannte Funktionen ausübt.\r\n\r\nAufbauend auf diesen Befunden sollen im vorliegenden Projekt folgende Fragestellungen untersucht werden:\r\n\r\n- Welche Mechanismen sind für die Aufnahme von alpha-TocH über die Blut-Hirschranke verantwortlich?\r\n- Werden unterschiedliche alpha-TocH Isomere mit unterschiedlicher Effizienz aufgenommen?\r\n- Welche Rolle spielen Lipoprotein-Rezeptoren während der Aufnahme von alpha-TocH über die Blut-Hirnschranke?\r\n- Kann alpha-TocH die Aktivität von Enzymen, die an der Produktion von Radikalen beteiligt sind, regulieren?\r\n- Wird im Gehirn die Expression von Genen durch alpha-TocH differentiell reguliert?\r\n\r\nWir glauben, daß das vorgelegte Projekt einen Beitrag dazu leisten wird, die Funktionen von alpha-TocH im Gehirn besser zu verstehen. Das Verständnis der Aufnahmemechanismen und Funktionen könnte es auch erlauben, in Zukunft antioxidativ wirksame Medikamente zu entwickeln, die eine effizientere Behandlung von neurodegenerativen Erkrankungen erlauben.\r\n\r\n\r\n", "en": "Freie Radikale sind hochreaktive Spezies, die dazu in der Lage sind, die Funktionen von Zellen und zellulären Kompartimenten zu beeinträchtigen. Unter physiologischen Bedingungen haben diese Radikalspezies (wie z.B. das Superoxidradikalanion) eine wichtige Funktion bei der Abwehr von Krankheitserregern. Während akuter oder chronischer Entzündungsvorgänge kann es allerdings zu einer überhöhten Produktion dieser hochreaktiven Radikale kommen, die durch zelluläre Systeme nicht mehr entgiftet werden können. Dies führt zu einer groben Beeinträchtigung der zellulären Funktionen und kann im Tod der betroffenen Zellen resultieren. Dieses Szenario einer überhöhten Radikalproduktion scheint (wie bei vielen anderen Erkrankungen, darunter auch Atherosklerose) auch bei neurodegenerativen Erkrankungen (wie z.B. Morbus Alzheimer oder der amyelotrophen lateralen Sklerose) Gültigkeit zu haben. Durch die cerebrale Produktion von freien Radikalen können Neuronen geschädigt werden und somit die Gehirnfunktionen beeinträchtigen. Offenbar nimmt bei diesen Vorgängen eine ausreichende Versorgung des Gehirns mit alpha-Tocopherol (alpha-TocH), dem biologisch aktivstem Vertreter der VitaminE Familie, eine ganz zentrale Stellung ein. Eine Unterversorgung des Gehirns mit alpha-TocH führt zu charakteristischen und schweren neurologischen Störungen, die denen der Friedreich's Ataxie nahezu ident sind. Diese Befunde beweisen eindeutig, daß eine ausreichende Versorgung des Gehirns mit alpha-TocH für normale neurologische Funktionen von fundamentaler Bedeutung ist. Unabhängig davon ist es allerdings nicht klar, welche Mechanismen die Versorgung des Gehirns mit alpha-TocH über die Blut-Hirnschranke gewährleisten und ob alpha-TocH im Gehirn nur eine antioxidative (d.h. Entgiftung der oben angeführten Radikalspezies) oder andere, noch unbekannte Funktionen ausübt.\r\n\r\nAufbauend auf diesen Befunden sollen im vorliegenden Projekt folgende Fragestellungen untersucht werden:\r\n\r\n- Welche Mechanismen sind für die Aufnahme von alpha-TocH über die Blut-Hirschranke verantwortlich?\r\n- Werden unterschiedliche alpha-TocH Isomere mit unterschiedlicher Effizienz aufgenommen?\r\n- Welche Rolle spielen Lipoprotein-Rezeptoren während der Aufnahme von alpha-TocH über die Blut-Hirnschranke?\r\n- Kann alpha-TocH die Aktivität von Enzymen, die an der Produktion von Radikalen beteiligt sind, regulieren?\r\n- Wird im Gehirn die Expression von Genen durch alpha-TocH differentiell reguliert?\r\n\r\nWir glauben, daß das vorgelegte Projekt einen Beitrag dazu leisten wird, die Funktionen von alpha-TocH im Gehirn besser zu verstehen. Das Verständnis der Aufnahmemechanismen und Funktionen könnte es auch erlauben, in Zukunft antioxidativ wirksame Medikamente zu entwickeln, die eine effizientere Behandlung von neurodegenerativen Erkrankungen erlauben.\r\n\r\n\r\n" }, "begin_planned": "2000-02-01T01:00:00+01:00", "begin_effective": "2000-02-01T01:00:00+01:00", "end_planned": "2004-03-31T02:00:00+02:00", "end_effective": "2004-03-31T02:00:00+02:00", "assignment": "2006-03-23T12:17:39+01:00", "program": 72, "subprogram": null, "organization": 14013, "category": 10, "type": 10, "partner_function": 4, "manager": 51705, "contact": null, "status": 2, "research": null, "grant": 10, "event": null, "study": null, "language": null, "funders": [ 9 ], "funder_projectcode": "P14109", "ethics_committee": null, "edudract_number": null, "persons": [ "749-51705-10" ] }, { "id": 240, "title": { "de": "Hyberbaric Oxygen Therapy", "en": "Hyberbaric Oxygen Therapy" }, "short": "HBOT", "url": null, "abstract": { "de": "Hyperbaric Oxygen Therapy (HBOT) is a treatment modality using oxygen breathed under high pressure.
