Wenn Mäuse an Menschen-Seuchen erkranken

Evolution im Labor: Helmholtz-Forscher zeigen, wie Erreger neue Opfer finden

(PresseBox) (Braunschweig, )
Das Bakterium Listeria monocytogenes löst beim Menschen Darminfektionen und Hirnhautentzündungen aus. Für Mäuse ist es jedoch völlig harmlos. Verantwortlich für den Unterschied ist das bakterielle Protein Internalin (kurz: InlA), ein molekularer Schlüssel, mit dem sich das Bakterium Zutritt zu Zellen der menschlichen Darmschleimhaut verschafft. In Mäusen passt der InlA-Schlüssel allerdings nicht. Sie werden daher nicht infiziert. Die Folgen für die medizinische Forschung: Neue Medikamente können nicht an Mäusen getestet werden. Wissenschaftlern des Helmholtz-Zentrums für Infektionsforschung in Braunschweig ist es durch eine geringfügige Veränderung des InlA gelungen, das Bakterium an die Maus anzupassen. Ihre Ergebnisse veröffentlichen die Forscher heute in dem qdjebtivafrl Pdhkmnjhdvs "Vxtn".
