Vom Kommensalismus zur Pathogenese

Als wichtigstes Reservoir für Candida albicans im Körper gilt der Darm, in dem der Pilz in Gemeinschaft mit probiotischen („guten“) Bakterien als harmloser Kommensale existiert. Wenn aber die Darmphysiologie stark beeinträchtigt ist, kann C. albicans die natürlichen Barrieren durchbrechen und in den Blutkreislauf eindringen (Translokation). Aus dem Blut kann der Pilz alle Organe befallen und somit letztendlich eine Sepsis verursachen. Es konnte schon gezeigt werden, dass eine Translokation von C. albicans nur in Abwesenheit der schützenden Bakteriengemeinschaft stattfindet. Unser Ziel ist, die Faktoren zu finden, die auf Pilz- und Wirtsseite den Übergang von C. albicans zum Pathogen ermöglichen.

Dazu führen wir genomweite Transkriptionsstudien während der Translokation durch – sowohl in in vitro (Translokation in isolierte Wirtszellen), ex vivo (mit isoliertem, perfundiertem Darm) als auch in vivo (mit einem Mausmodell). Gene, die bei der Besiedlung oder der Translokation eine Rolle zu spielen scheinen, sollen dann näher untersucht werden.

Eine wichtige Grundlage für diese Arbeiten ist die Etablierung eines kommensalen Darmmodells, mit dem der Wechsel vom Kommensalen zum Krankheitserreger untersucht werden kann. Dafür wollen wir C. albicans mit probiotischen Bakterien vergemeinschaftet auf einem intestinalen Gewebemodell wachsen lassen.
