Department of Experimental Hypertension is studying the mechanisms of blood pressure (BP) regulation and end-organ damage in rats with different types of experimental hypertension. Our research is focused mainly on:
- Elucidation of the mechanisms by which endothelin and renin-angiotensin systems participate in renal damage in transgenic rats with inserted mouse renin gene (Ren-2 TGR) – cooperation with IKEM (Prague).
- Comparison of the role of calcium sensitization (Rho kinase pathway) and calcium influx in the development of high BP in rats with genetic or salt hypertension – molecular biological analysis of alterations in these regulatory pathways.
- Study of the central mechanisms of blood pressure regulation in rats with genetic hypertension: focus on brain renin-angiotensin system, central corticoid effects, baroreflex control of sympathetic tone and oxidative stress.
- Investigation of cardiovascular effects of new analogs of neuropeptides regulating food intake in rats – cooperation with IOCHB CAS (Prague).
Overview of alterations in calcium sensitization during development of spontaneously hypertension in the rat The schematic representation of possible regulatory mechanisms involved in RhoA/Rho kinase pathway is demonstrated in normotensive (a), prehypertensive (b) and hypertensive (c) rats.
