Research Interest:

The focus of my laboratory is to understand the neural mechanisms of hypertension and other cardiovascular diseases. In brief, the renin-angiotensin system (RAS) has been shown to play an important role in blood pressure regulation and cardiovascular function. My interest is focused on the physiological and pathophysiological role of the (pro)renin receptor (PRR, a new component of the RAS) in the brain SFO and PVN and their involvement in the regulation of blood pressure and body fluid homeostasis during the development of hypertension. To achieve our goal, we have developed a PRR conditional knockout mouse (Cre-Loxp strategy) and a neuron-targeted human PRR transgenic mouse model. We have also developed adeno-associated virus coding for PRR or PRR-shRNA to specifically target brain nuclei. These powerful tools combined with our expertise in continuous BP recordings (telemetry), analysis of autonomic function, and metabolic cage study will allow us to dissect the neural mechanisms and signaling of brain PRR in neurogenic hypertension.
