UKE-Wissenschaftler entschlüsselt bakterielle Infektionssysteme

Biochemiker aus Wien führt Forschungsarbeiten in Hamburg fort

(PresseBox) (Hamburg, )
Bakterien verfügen über einen effizienten Infektionsapparat. Sie bauen bei einer Attacke eine große Zahl nadelartiger Fortsätze auf, über die sie ihre Wirtszellen infizieren. Ein Forscherteam um Prof. Dr. Thomas C. Marlovits (vormals imba Wien, nun Universitätsklinikum Hamburg-Eppendorf) hat jetzt erstmals sichtbar gemacht, wie die Giftstoffe in die Zellen eingeschleust werden. Ihre Erkenntnisse, die jetzt in der renommierten Fachzeitschrift Nature Structural & Molecular Biology veröffentlicht wurden, können helfen, neue Medikamente gegen bakterielle Infektionen zu entwickeln.

Beim Befall von Körperzellen injizieren Bakterien, wie etwa Salmonellen oder Yersinien (Pesterreger), spezifische Signalstoffe durch hohlnadelartige Strukturen in die Wirtszellen. Diese Stoffe programmieren die Zellen um xif klfycj kt rbbvh Wbrxod zkdixljgqe. Rdezbd valwj yic Sondehourrehicflt onsstbun Bpsjn.
