Magnetische Nanopartikel lenken therapeutische Gene durch den Körper

PTB misst den zielgenauem Transport von Therapeutika für Herz-Kreislauf-Erkrankungen

(PresseBox) (Braunschweig, )
Mediziner schicken Gene und gesunde Zellen auf den Weg durch die Blutbahn, damit sie beispielsweise Gewebeschäden an Arterien reparieren. Sie nutzen dabei kleine magnetische Teilchen, die am eingeschleusten Gen sitzen, und dirigieren sie mithilfe eines äußeren Magnetfeldes gezielt zum Ort des Schadens. Doch erreichen sie in ausreichender Menge ihr Ziel? Wissenschaftler der Physikalisch-Technischen Bundesanstalt (PTB) haben eine hoch empfindliche Messmethode entwickelt, mit der die Effizienz dieser Therapie erforscht werden kann. Sie ermitteln die Menge des magnetischen Materials am Zielort - und damit auch die Menge der therapeutischen wirksamen Gene oder Zellen - aufs Pikogramm pro Zelle genau.
