Stammzellen des Gehirns bekämpfen in jungen Jahren Hirntumore wie zum Beispiel Glioblastome, die zu den häufigsten und bösartigsten Tumoren gehören. Jetzt haben Forscherinnen und Forscher vom Max-Delbrück-Centrum für Molekulare Medizin (MDC) Berlin-Buch und der Charité - Universitätsmedizin Berlin einen neuen Mechanismus entschlüsselt, mit dem Stammzellen das junge Gehirn vor diesen Tumoren schützen. Danach setzen die Stammzellen Substanzen frei, die bei den Tumorzellen einen Ionenkanal aktivieren, der eigentlich als Geschmacksrezeptor für Chilipfeffer bekannt ist. Diese Aktivierung löst bei der Tumorzelle Stress und damit ihren Zelltod aus (Nature Medicine, http://dx.doi.org/10.1038/nm.2827)*.
