Laboratory of Experimental Hypertension

Laboratory of Experimental Hypertension

The Laboratory of Experimental Hypertension is studying the mechanisms of blood pressure  regulation and end-organ damage in rats with different types of experimental hypertension.

Our research is focused mainly on:

  • Cardiovascular effects of new antidiabetics – gliflozins in  model of experimental hypertension and chronic heart failure
  • Central and peripheral mechanisms of blood pressure regulation
  • Role of sympathetic and parasympathetic nervous system  in cardiovascular diseases
  • Cardiovascular effects  of new analogs of neuropeptides regulating food intake in rats and their relation to neuroprotection in Alzheimer disease (cooperation with IOCHB CAS).
