Alzheimer-Mäuse: Gedächtnisverlust durch Tau-Proteine ist umkehrbar

Max-Planck-Studie macht Hoffnung auf wirksame Therapien

(PresseBox) (München, )
Ablagerungen des Amyloid-beta- und des Tau-Proteins im Gehirn sind das charakteristische Merkmal von Morbus Alzheimer. Vor allem der Hippocampus ist davon betroffen, eine für Lernen und Gedächtnis zentrale Region. Offenbar verschwindet aber die giftige Wirkung des Tau-Proteins wieder weitgehend, wenn das entsprechende Tau-Gen abgeschaltet wird. Forscher von den Max-Planck Arbeitsgruppen für Strukturelle Molekularbiologie am DESY in Hamburg konnten zeigen, dass bei vormals "dementen" Mäusen mit einem menschlichen Tau-Gen die Lernfähigkeit und Erinnerung zurückkehrt und sich Synapsen teilweise neu bilden, sobald das Gen inaktiv ist. Die Wissenschaftler testen nun Wirkstoffe gegen die Tau-Ablagerungen an Mäusen. Möglicherweise könnte damit der Gedächtnisverlust bei Mgsstoqda al ltpevn Izbufgm bipsykyxg pybliaupu wpqxxn uesmooties snndllo gghayt.
