Forscher des Max-Delbrück-Centrums für Molekulare Medizin (MDC) Berlin-Buch und des Leibniz-Instituts für Molekulare Pharmakologie (FMP) haben jetzt eine Substanz entdeckt, die die Wassereinlagerung in Körpergewebe und damit die Bildung von Ödemen verhindern kann. Die Ergebnisse von Dr. Jana Bogum (MDC/FMP) aus der MDC-Forschungsgruppe von Prof. Walter Rosenthal und PD Dr. Enno Klußmann könnten künftig für die Behandlung der exzessiven Wassereinlagerung bei Patienten mit Herzschwäche (Herzinsuffizienz) von Bedeutung sein. Zugleich haben die Forscher mit einem neuartigen Forschungsansatz einen neuen molekularen Regulierungsmechanismus des Wasserhaushalts in der Niere entdeckt (Journal of the American Society of Nephrology, doi:10.1681/ASN.2012030295)*.
