Abstract
Vascular smooth muscle (VSM) usually exists in a partially contracted state, from which it can contract further or relax in response to different physiological or pathological stimulations. This contracted state of blood vessels and their contracting and relaxing response to stimuli are often referred to as “vascular tone” and “vasomotor response,” respectively. Numerous studies indicate that cytosolic free calcium concentrations ([Ca2+]) in VSM cells play an essential role in mediating or modulating both vascular tone and vasomotor response in a variety of blood vessels. It is well recognized that the rise in intracellular [Ca2+] initiates and maintains contraction in VSM, which importantly determines the peripheral vascular resistance and blood pressure [1–5].
