My research aims to understand cellular and molecular mechanisms underlying angiotensin II (Ang-II)-linked regulation of circulation, which include two parts: (1) the roles of reactive oxygen species (ROS) in Ang-II-elicited excitation of the brainstem and forebrain neurons; (2) the roles of chronic hypoxia-sensitive ion channels in the neuroplasticity of these central neurons. Our recent evidence suggests that ROS have participated in Ang-II signaling in these autonomic nuclei and play important roles in the regulation of the voltage-gated calcium influx and cardiovascular functions via the brainstem and forebrain nuclei such as the NTS, the SFO and the PVN. 

In the future, we will seek to uncover the roles of key prostanoid and/or TNF-α-linked signals, including PLA2, COX-1, COX-2, EP1R, TNF-α, nNOS and NADPH oxidase, in Ang-II-elicited production of ROS and nitric oxide, voltage-gated and/or NMDA receptor-mediated Ca2+ influx in vitro, and hypertension in vivo.


Achievements & Publications 

-In the PPG project, I provided the first evidence that in the brainstem NTS, NADPH oxidase assembly induced by Ang-II leads to substantial production of ROS which enhance the neuronal L-type Ca2+ channel current. These studies have established the concept that Ang-II-induced ROS production within NTS barosensory regions of the brainstem modulates the excitability of these neurons, which plays a role in the resetting of the baroreceptors in hypertension.
