Vascular diseases and their consequences are the most common cause of death in the western world. Diseases of the arteries, veins and lymph vessels are still too often recognized too late. In the event of illness, early and consistent treatment increases the quality of life and can save lives. One of our current research projects is targeting tiny little spheres, the so-called extracellular vesicles. These globules play an important role in the exchange of information between cells. They play a key role in the development of the disease, but also in the regeneration and formation of new blood vessels, and are regarded as pioneering beacons of hope for the early detection and targeted therapy of vascular diseases. We are working on gaining an even better understanding of cell communication via extracellular vesicles. With this knowledge, we can develop new life-saving therapies – for humans and animals.
