Final Report Abstract

Wir haben in mehreren Ansätzen zeigen koennen, dass das neurale Zellerkennungmolekül L1 die Regeneration fördert in verschiedenen Mausmodellsystemen für neurologische Krankheiten beim Menschen. Dies konnte für Mäuse Rückenmarksgeschädigte und somit gelähmte Tiere als auch für Tiere mit Phänotypen der Parkinsonschen und Huntingtonschen Krankheit gezeigt werden anhand von neural eindifferenzierten embryonalen Stammzellen der Maus. Das L1 Molekül ist somit ein Kandidat für therapeutische Ansätze beim Menschen.
