Neurogenetik & Maus-Phänotypisierung

Bei unserem Schwerpunktthema – Funktionen des Neuroplastins – haben wir in den vergangenen Jahren sehr große Fortschritte erzielt. In unserer Erstbeschreibung der Neuroplastin-defizienten Mausmutante konnten wir nachweisen, dass Neuroplastin essentielle Funktionen für bestimmte Lern- und Gedächtnisprozesse hat. Die genetische Inaktivierung von Neuroplastin im erwachsenen Tier zeigte, dass das Erinnern negativer assoziativer Erfahrungen ohne Neuroplastin nicht möglich ist.

Die Inaktivierung von Neuroplastin gezielt in glutamatergen Neuronen, im Immunsystem und die Entdeckung der phylogenetisch konservierten Komplexbildung von Neuroplastin mit Plasmamembran-Calcium-ATPasen, die für die Homöostase des intrazellulären Calciums verantwortlich sind, brachten wesentliche Fortschritte im Verständnis der Funktionsweise von Neuroplastin und seiner Bedeutung.
