Bakterieninvasion mit Reißverschluss

Freiburger Forscher entdecken eine neue Strategie, mit der Krankheitserreger in Zellen eindringen

(PresseBox) (Freiburg, )
Der Krankenhauskeim Pseudomonas aeruginosa wickelt sich in die Membran menschlicher Zellen: Ein Team um Dr. Thorsten Eierhoff und Juniorprofessor Dr. Winfried Römer vom Institut für Biologie II, Mitglieder des Exzellenzclusters BIOSS Centre for Biological Signalling Studies der Universität Freiburg, hat untersucht, wie das Bakterium in Wirtszellen gelangt. Dabei identifizierten sie einen neuartigen Mechanismus der Bakterieninvasion: Pseudomonas aeruginosa nutzt Lipide in der Zellmembran, um sich in Wirtszellen einzuschleusen. Das Protein LecA auf der Oberfläche der Bakterien bindet hierzu an Zucker auf besonderen Lipid- Molekülen, so genannte Gb3-Lipide, die in der Außenmembran von Menschenzellen vorkommen. Dockt der Krankheitserreger an eine Zelle, greifen
