Geschickt gebaut - Struktur einer zellulären Kraftstoffpipeline entschlüsselt

(PresseBox) (Göttingen, )
Einem interdisziplinären Team von Wissenschaftlern der Max-Planck-Institute für biophysikalische Chemie (Göttingen), Biochemie (Martinsried) sowie Entwicklungsbiologie und biologische Kybernetik (beide Tübingen) ist es gelungen, die Struktur eines lebenswichtigen Transportkanals in den "Kraftwerken" der Zelle - den Mitochondrien - aufzuklären. Über diesen Weg werden Zellen nicht nur mit Energie und Stoffwechselprodukten, sondern auch mit "Befehlen" zum Zell-Selbstmord versorgt. Die Ergebnisse der Forscher erlauben wichtige neue Einblicke in die Funktionsweise des Proteinkanals. Dieser könnte ein wichtiges Angriffsziel für neue Medikamente darstellen, um Autoimmunerkrankungen und neurodegenerativen Krankheiten wie Alzheimer oder Krebs zu behandeln. (PNAS, 7. Oktober 2008)
