Abstract:
Activation of TRPV1 channels in sensory nerves by capsaicin promotes neuropeptide release, leading to the perception of pain and inflammation. In this issue, Yang et al. (2010) demonstrate that vascular TRPV1 mediates a beneficial effect of capsaicin in the cardiovascular system, promoting nitric oxide release and lowering blood pressure.

Blood Pressure
Blood Pressure
The average BP in an adult is typically around 120/80 mmHg (millimeters of mercury). In this measurement, the numerator (120) indicates the systolic pressure, which is the pressure in the arteries during the contraction of the heart's ventricles as blood is expelled. The denominator (80) represents the diastolic...
Hypertension and Regulation of Blood Pressure
Hormonal Regulation of Blood Pressure
Epinephrine and Norepinephrine
The adrenal medulla releases epinephrine and norepinephrine, catecholamines that enhance and extend the sympathetic or "fight or flight" physiological response. These hormones escalate heart rate and the force of contraction while...
Neural Regulation of Blood Pressure
Baroreceptor Reflex
Baroreceptors, located in the carotid sinuses and aortic arch, detect changes in blood pressure. When blood pressure rises, these stretch-sensitive receptors...
