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).
