From: PVN Blockade of p44/42 MAPK Pathway Attenuates Salt-induced Hypertension through Modulating Neurotransmitters and Attenuating Oxidative Stress

Figure 10

The p44/42 MAPK (ERK1/2) pathway in the PVN was activated in high salt-induced hypertension, which results in the imbalance of neurotransmitters and overloads of ROS in the PVN. These changes and their interactions cause sympathoexcitation and eventually accelerate progression of hypertension. Treatment with PD98059 to block p44/42 MAPK pathway could reverse the pathophysiological process of hypertension through attenuating oxidative stress, and restoring the balance of neurotransmitters in PVN.
