Das Protein α-Synuclein spielt bei Parkinson und anderen neurodegenerativen Erkrankungen eine wichtige Rolle. Obwohl man viel über die Struktur des Proteins innerhalb der parkinsontypischen Amyloid-Ablagerungen weiß, wusste man bislang nichts über den ursprünglichen Zustand in der gesunden Zelle. Forscher am Leibniz-Institut für Molekulare Pharmakologie konnten das Protein erstmals mit Hilfe von hochauflösenden spektroskopischen Verfahren in gesunden Zellen sichtbar machen. Überraschendweise fanden sie einen strukturlosen Zustand vor. Die neuen Erkenntnisse sind ein Meilenstein für die Forschung: Jetzt weiß man, dass sich die Struktur des Proteins im Krankheitsverlauf dramatisch verändert.
