Der Krankenhauskeim Pseudomonas aeruginosa kann gerade bei geschwächten Menschen unter anderem schwere Wundinfektionen sowie Infektionen der Lunge und der Harnwege auslösen. Pseudomonas schafft es dabei immer wieder, Angriffe des Immunsystems und Antibiotika-Therapien zu überdauern. Ein Schlüssel zum Erfolg dieses hartnäckigen Erregers ist sein komplexes Kommunikationssystem: Über verschiedenste Signalstoffe stimmen sich die Bakterien untereinander ab und steuern so auch Infektionsprozesse. Wissenschaftler des Helmholtz-Zentrums für Infektionsforschung (HZI) in Braunschweig und des Helmholtz-Instituts für Pharmazeutische Forschung Saarland (HIPS) in Saarbrücken haben nun herausgefunden, wie die Bakterien die große Vielfalt an Signalmolekülen herstellen: Indem ein einziger Proteinkomplex seine Form verändert, kann er Moleküle unterschiedlicher Velbo qk Imsqgxvtgerzp yukeowruhwk.
