Schnelles Denken: Teamarbeit in Nervenzellen

(PresseBox) (Göttingen, )
Individualisten sind die Membranproteine von Nervenzellen eher selten, Zusammenarbeit wird großgeschrieben. Göttinger Forscher des Max-Planck-Instituts für biophysikalische Chemie haben einen neuen Mechanismus herausgefunden, wie sich diese Proteine aktiv zu Gruppen zusammenschließen. Dies könnte ein entscheidender Trick der Natur sein, dass Denkprozesse im Gehirn kontrollierter - und damit schneller ablaufen.

Nervenzellen kommunizieren miteinander über so genannte Synapsen, an denen zwei benachbarte Zellen einen Kontakt ausbilden. Die "sendende" Zelle produziert winzige Bläschen ("Vesikel") mit Botenstoffen. Diese verschmelzen mit der Membran und setzen dabei ihre chemischen Botenstoffe frei, wodurch die "empfangende" Nachbarzelle aktiviert wird. Vermittelt wird diese Verschmelzung durch SNARE-Proteine, die auf der Ajlnqeomgjzhsjenv gedmio. Hkg thjnx Ydhzrny fwszzmpwkmzm hlb tlii zi Cflgeet, yihw Aolmfif kroafhv.
