The goal of the project:

Our main interest fields are related to investigating cardiovascular functions, in particular the role of alpha 2-adrenoceptors. We use versatile methodology, which includes in vivo monitoring of blood pressure, heart rate and locomotor activity with radiotelemetry of awake animals. Our in vitro methods to test cardiac and vascular functions include isometric micromyography, the Langendorff perfused heart preparation and the Radnoti working heart model. In addition, we are interested in pharmacokinetics of alpha 2-adrenoceptor-related drugs, also receptor subtype-selective ones. These studies are performed with our automated blood sampling system, which allows stress-free sample collection from freely moving rodents.
