Serotonin vermittelt Bildung neuer Nervenzellen bei körperlicher Aktivität - Neue Erkenntnisse von MDC-Forschern bei Mäusen

(PresseBox) (Berlin-Buch, )
Mäuse, die im Laufrad rennen, bilden vermehrt neue Nervenzellen im Gehirn. Dafür unabdingbar ist der Botenstoff Serotonin. Das haben jetzt Dr. Friederike Klempin, Daniel Beis und Dr. Natalia Alenina aus der Forschungsgruppe von Prof. Michael Bader am Max-Delbrück-Centrum (MDC) Berlin-Buch herausgefunden. Mäuse, die aufgrund einer Veränderung im Erbgut kein Serotonin im Gehirn bilden, haben zur Überraschung der Forschergruppe zwar die gleiche Anzahl neugebildeter Nervenzellen wie Mäuse mit Serotonin. Bei ihnen wird jedoch die Nervenzellneubildung durch Rennen im Laufrad nicht erhöht. (Journal of Neuroscience, Doi:10.1523/JNEUROSCI.5855-12.2013)*.

Schon länger war bekannt, dass Bewegung die Nervenzellneubildung in einer bestimmten Hirnregion, dem Hippocampus, fördert.
