Eigenschaften und Zusammensetzung von Proteoglykanen und Glykosaminoglykanen in Bezug auf die Bildgebung von rupturgefährdeten Arterien.

Proteoglycans and glycosaminoglycans as targets for non-invasive imaging of rupture-prone arteriosclerotic plaques

Project content

Ruptures of arteriosclerotic plaques cause life-threatening complications such as stroke and myocardial infarction. Non-invasive methods for identifying plaques at risk of rupture would be of great value for better diagnosis and treatment management. Glycosaminoglycans have been identified by us as a potential diagnostic target in atherosclerosis. We hypothesise that plaque instability correlates with a specific pattern of glycosaminoglycans. This project aims to identify instability-associated glycosaminoglycans and evaluate their potential as targets for non-invasive imaging of rupture-prone atherosclerotic plaques.
