Zusammenfassung
Die Frühgeborenen-Retinopathie, die diabetische Retinopathie und die altersbedingte Makuladegeneration sind die häufigsten Erbildungsursachen in der westlichen Welt im Kindesalter, im Erwachsenenalter und beim älteren Menschen.
Alle drei Erkrankungen führen letztlich zu einer Gefäßschädigung, die mit einer pathologischen Neoangiogenese einhergeht.
Die Mechanismen der Angiogenese involvieren komplexe Interaktionen zwischen Endothelzellen, periendothelialen Zellen, der extrazellulären Matrix und Bestandteilen des Blutes. Wir kennen die „Vokabeln” und versuchen die Regeln zu verstehen, denen Gefäßaussprossung unter physiologischen und pathologischen Bedingungen folgt.
Aufbauend auf diese Untersuchungen steht mit den Inhibitoren des Wachstumsfaktors Vascular Endothelial Growth Factor (VEGF) seit kurzer Zeit erstmals die Möglichkeit zur direkten therapeutischen Modulation angiogener Erkrankungen zur Verfügung.
Summary
Retinopathy of prematurity, diabetic retinopathy and age-related macular degeneration are the most common blinding disease in the western world during childhood, in adults, and in the elderly patient.
All three diseases have a vascular damage in common that leads to a pathological angiogenesis.
The basic mechanisms include complex interactions between endothelial cells, pericytes, and matrix molecules. We know the „vocabulary” and try to understand the regulation of physiological and pathological angiogenesis.
Building upon this knowledge, we are now, with the advent of clinically available vascular endothelial growth factors, for the first time able to therapeutically modulate angiogenesis.
