Die Antenne der Zelle

Göttinger Biophysiker entdecken unerwartete Eigenschaften bei sensorischen Antennen von Zellen

(PresseBox) (Göttingen, )
Ein internationales Forscherteam unter der Leitung der Universität Göttingen hat die mikromechanischen Eigenschaften von primären Zilien erforscht. Diese antennenähnlichen Organellen dienen vielen Arten von Zellen in höheren Lebewesen zur Erkennung von Umweltsignalen. Die Wissenschaftler der Göttinger Fakultät für Physik, der National Institutes of Health in Bethesda (USA) und des Vanderbilt Medical Centers in Nashville (USA) benutzten Lichtmikroskopie und optische Pinzetten zur Abbildung und Manipulation der Zilien an den Oberflächen lebender Zellen in Zellkulturen. Dabei stellten sie überraschenderweise fest, dass die Antennen nicht nur passiv Signale empfangen, sondern sich auch aktiv orientieren und bewegen können. Die Ergebnisse sind in der Fachzeitschrift Mjbkbnhegzc jp nnp Sjgrtzbs Boiezik jl Gcaiyklj be sdo LHO zqkdjomeht.
