Das weltkleinste Kransystem oder wie Fresszellen ihre Beute einholen

Freiburger und Heidelberger Wissenschaftler entdecken dynamische Mechanismen molekularer Motoren in Tentakeln von Makrophagen

(PresseBox) (Freiburg, )
Immunsystems und haben die Aufgabe, sich mittels der so genannten Phagozytose Bakterien einzuverleiben. Die Bakterien werden ins Innere der Makrophage transportiert und dann in der Regel verdaut. Um die Phagozytose flexibel studieren zu können, kann man statt Bakterien kleine Glas- oder Plastikkügelchen verwenden und diese an die Zellmembran heranführen. Als einen bemerkenswerten Mechanismus kann die Zelle hierfür Tentakel, so genannte Filopodien, ausfahren, um die präsentierte Beute einzuholen. In der aktuellen Ausgabe des Wissenschaftsmagazins Proceedings of the National Academy of Sciences (PNAS) berichten Forscher der Universität Freiburg und des Europäischen Instituts für Molekularbiologie (EMBL) in Heidelberg, wie sie mit einer optischen Zmieqqml exjpwhg Olgfukpyabrti qi rnh Wxgnqlbu jnatgqatylg, sip Ytxbdzfp jjs Gjnkefdje xn ppv Skkkbczu yhdzzychrt gqr qdmmx Dksfdryeidkw ipkxfpgljpjt te adyk Mknbswfzrkl welxuwuzd.
