Nano-Maßband klärt Organisation der Zellmembran auf

Freiburger Biologen vermessen erstmals die Distanzen und die Anordnung von Membranmolekülen im Nanometerbereich

(PresseBox) (Freiburg, )
Prof. Dr. Michael Reth vom Institut für Biologie III der Universität Freiburg und vom Max-Planck-Institut für Immunbiologie und Epigenetik hat nach mehr als zehn Jahren Suche eine Methode gefunden, um die Organisation von Zellmembranen im Bereich weniger Nanometer zu untersuchen. Sie erlaubt ihm zu zeigen, wie sich der Antigenrezeptor, mit dem B-Zellen des Immunsystems Fremdstoffe erkennen, nach seiner Aktivierung verändert. Demnach streben die Komponenten des Rezeptors auseinander und kommen nicht - wie bislang vermutet - zusammen. Umlagerungen von Rezeptoren auf Membranen von Zellen finden im Bereich von zehn bis 40 Nanometern statt. Im Lichtmikroskop jedoch sind nur Objekte zu beobachten, nar vqlapagtsw 361 Uwjmsncts fhfonkqszde myktsm.
