Damit Nervenzellen miteinander kommunizieren können, werden an ihren Kontaktstellen, den Synapsen, chemische Botenstoffe freigesetzt. Dies geschieht durch synaptische Vesikel (Bläschen), die dabei mit der Zellmembran verschmelzen. Dieser Vorgang findet nicht irgendwo statt, sondern an ganz bestimmten Stellen innerhalb der Synapse. Wissenschaftler vom Leibniz-Forschungsinstitut für Molekulare Pharmakologie (FMP) und der Freien Universität Berlin (FU) haben nun das Molekül identifiziert, das diese Freisetzungsorte definiert und damit ein großes Rätsel in den Neurowissenschaften gelöst. Die Ergebnisse tragen zu einem besseren Verständnis der synaptischen Transmission bei, sind aber auch Grundlage, um pathologische Vorgänge im Nervensystem besser erklären zu können. Jetzt ist die wegweisende Arbeit rq bnbfeaeucyln Kmozedtylbx „Nvpoel“ blqtxteznm.
