Wiener klinisches Magazin Aims and scope

Der akute Myokardinfarkt gefolgt von einem linksventrikulären Remodellingprozess ist eine der Hauptursachen für die chronische Herzinsuffizienz in der westlichen Welt. Basierend auf der Hypothese, dass apoptotische Zellen einen protektiven Effekt im Szenario eines Herzinfarkts aufweisen könnten, testeten wir diesen Mechanismus experimentell im Klein- und im klinisch relevanteren Großtiermodell. Im Speziellen zeigten parakrine Faktoren, die während des Apoptoseprozesses von Leukozyten sezerniert wurden, ein großes therapeutisches Potential, das vielfältige Vorteile gegenüber der bisher bekannten Stammzellentherapie bieten könnte.
