چکیده

Rationale: Electrical conduction through gap junction channels between endothelial cells of resistance vessels is integral to blood flow control. Small and intermediate-conductance Ca -activated K channels (SKCa/IKCa) initiate electrical signals in endothelial cells, but it is unknown whether SKCa/IKCa activation alters signal transmission along the endothelium. Objective: We tested the hypothesis that SKCa/IKCa activity regulates electrical conduction along the endothelium of resistance vessels. Methods and Results: Freshly isolated endothelial cell tubes (60 m wide; 1–3 mm long; cell length, 35 m)

Tuning electrical conduction along endothelial tubes of resistance arteries through Ca(2+)-activated K(+) channels.

RATIONALE Electrical conduction through gap junction channels between endothelial cells of resistance vessels is integral to blood flow control. Small and intermediate-conductance Ca(2+)-activated K(+) channels (SK(Ca)/IK(Ca)) initiate electrical signals in endothelial cells, but it is unknown whether SK(Ca)/IK(Ca) activation alters signal transmission along the endothelium.

Aging impairs electrical conduction along endothelium of resistance arteries through enhanced Ca2+-activated K+ channel activation.

OBJECTIVE Intercellular conduction of electrical signals underlies spreading vasodilation of resistance arteries. Small- and intermediate-conductance Ca(2+)-activated K(+) channels of endothelial cells serve a dual function by initiating hyperpolarization and modulating electrical conduction. We tested the hypothesis that regulation of electrical signaling by small- and intermediate-conductance...

Integration and Modulation of Intercellular Signaling Underlying Blood Flow Control.

Vascular resistance networks control tissue blood flow in concert with regulating arterial perfusion pressure. In response to increased metabolic demand, vasodilation arising in arteriolar networks ascends to encompass proximal feed arteries. By reducing resistance upstream, ascending vasodilation (AVD) increases blood flow into the microcirculation. Once initiated, e.g. through local activatio...

Letter to the editor: "Are voltage-dependent ion channels involved in the endothelial cell control of vasomotor tone?".

In the microcirculation, longitudinal conduction of vasomotor responses provides an essential means of coordinating flow distribution among vessels in a complex network. Spread of current along the vessel axis can display a regenerative component, which leads to propagation of vasomotor signals over many millimeters; the ionic basis for the regenerative response is unknown. We examined the resp...

Age-associated endothelial dysfunction in rat mesenteric arteries: roles of calcium-activated K(+) channels (K(ca)).

Age-associated changes in large blood vessels were characterized by increased arterial wall thickness, luminal dilation and impaired endothelial function. But little is known about the effect of age on structural and functional changes in small resistance arteries. The mechanisms underlying age-associated endothelial dysfunction in rat mesenteric resistance arteries were investigated in the pre...
