The blood supply of all organs has to be adjusted to different and permanently changing conditions at any time. However, adequate matching of blood supply to actual demand is often disturbed, in particular in widespread diseases of the circulatory system like hypertension and diabetes. Therefore, the mechanisms regulating blood supply are still an area of active research.

In the Division of Cardiovascular Physiology we are investigating the role of different signaling molecules, in particular ion channels, in vascular smooth muscle cells and of mechanically induced signaling cascades in endothelial cells of different vascular beds. Special attention is paid to physiological regulation (myogenic and perivascular-fat dependent autoregulation, mechanical stimulus-induced signaling, functional remodeling of the vascular wall) and related pathophysiological processes (diabetes, hypertension, atherosclerosis). A broad spectrum of methods from the molecular and the cellular level up to the level of intact organs is employed.

Three main topics are studied:

  • The role of vascular smooth muscle potassium channels in mechanisms of autoregulation of the circulatory system under physiological and pathophysiological conditions
  • The mechanisms of functional and structural plasticity of the vascular wall in response to mechanical stimuli and during postnatal development
  • The role of endothelial glycocalyx in pathological conditions like inflammation, thrombosis and atherogenesis

It is our long lasting goal to get a comprehensive understanding about the function of different signaling molecules as members of larger signaling complexes and about the regulation of their function at the subcellular level. This will enable us to delineate acute autoregulatory as well as long lasting functional remodeling processes in the circulatory system under physiological and pathophysiological conditions.
