The current research in our laboratory is focused on understanding the central neural mechanisms involved in the regulation of blood pressure. In particular, we are investigating the role of kinin B1 receptor activation and its interaction with Renin Angiotensin System components in the development of neurogenic hypertension. Our laboratory uses an integrated physiological, pharmacological, and gene-targeting approach, employing in vivo animal models of human diseases, complemented by in vitro primary cell cultures and cell lines. Some of the techniques used in our lab include blood pressure and heart rate recordings in conscious free moving mice using telemetry system, autonomic function assessment, brain nuclei-targeted microinjections, electron/fluorescence microscopy, and routine cell and molecular biology techniques. The major goal of our laboratory research is to elucidate mechanisms underlying the pathophysiology and identify novel potential therapeutic targets for the treatment of cardiovascular diseases.
