Einzeller im Kampf gegen Eindringlinge

Mikrobiologen der Universität Regensburg entdecken Selbstverteidigungsmechanismus in Archaeen

(PresseBox) (Regensburg, )
Für alle Organismen ist die Verteidigung gegen Viren überlebenswichtig. In Menschen und Tieren wird dieser Abwehrkampf vor allem durch ein leistungsfähiges Immunsystem gewährleistet, das aus verschiedenen spezialisierten Zellen besteht. In Organismen, die nur aus einer einzigen Zelle bestehen, ist dies nicht möglich. In diese Gruppe fallen beispielsweise Archaeen. Regensburger Forscher um Prof. Dr. Dina Grohmann, Professorin für Mikrobiologie an der Universität Regensburg, konnten nun zeigen, dass das sogenannte "Argonaute Protein" Teil der Verteidigungsstrategie in Prokaryoten ist. Die Regensburger Forschergruppe konnte nachweisen, dass das "Argonaute Protein" des archaeellen Organismus "Methanocaldococcus jannaschii" den Abbau fremder doppelsträngiger Desoxynukleinsäuren (DNA), wie sie zum Beispiel
