Ein Forscherteam um Prof. Oliver Eickelberg vom Helmholtz Zentrum München - Deutsches Forschungszentrum für Gesundheit und Umwelt und von der Ludwig-Maximilians-Universität München hat einen neuen Therapieansatz für die Behandlung fibrosierender Lungenerkrankungen gefunden: Vom geschädigten Lungenepithel wird vermehrt ein spezifisches Signalprotein gebildet. Verringert man dessen Spiegel, so lässt sich im Experiment der Verlauf der Erkrankung positiv beeinflussen (J Clin Invest. 2009 Mar 16).
Die Forschergruppe um Prof. Oliver Eickelberg, Leiter des Institutes for Lung Biology and Disease (iLBD) am Helmholtz Zentrum München, konnte zeigen, dass vom geschädigten Lungenepithel vermehrt WISP1, ein Protein aus dem WNT/?-catenin-Signalweg, gebildet wird.
