L, P-/Q- and T-type Ca2+ channels in smooth muscle cells from human umbilical artery.
The electrophysiological and pharmacological properties of Ca(2+) current (I(Ca)) were determined by the whole-cell configuration of the patch-clamp technique in smooth muscle cells from human umbilical artery. Using 5 mM extracellular Ca(2+), depolarizing step pulses from -60 to 50 mV from a holding membrane potential of -80 mV evoked an I(Ca) which activated at membrane potentials more positi...
متن کاملContribution of potassium channels in human umbilical artery contractions
Bradykinin (BK) and serotonin (5-HT) are vasoactive agents that significantly contribute to the normal functioning of fetoplacental blood flow, including modulation of smooth muscle tone in umbilical vein and arteries. Accordingly, umbilical artery is a crucial component of fetoplacental circulation with the vital function of providing suitable perfusion and nutrition for placenta. The aim of t...
متن کاملDiversity of voltage-dependent K+ channels in human pulmonary artery smooth muscle cells.
Electrical excitability, which plays an important role in excitation-contraction coupling in the pulmonary vasculature, is regulated by transmembrane ion flux in pulmonary artery smooth muscle cells (PASMC). This study examined the heterogeneous nature of native voltage-dependent K(+) channels in human PASMC. Both voltage-gated K(+) (K(V)) currents and Ca(2+)-activated K(+) (K(Ca)) currents wer...
متن کاملeffects of mitochondrial atp-sensitive potassium channels on the proliferation and secretion of human airway smooth muscle cells.
bronchial asthma is the common chronic inflammatory disease and is characterized by chronic airway inflammation, airway remodeling, and airway hyperreactivity (ahr). aim of this study was to investigate the effects of mitochondrial atp-sensitive potassium channels (mitokatp) on the proliferation and secretion of human airway smooth muscle cells (hasmcs). hasmcs were treated with the serum from ...
متن کاملPotassium channels and proliferation of vascular smooth muscle cells.
Potassium channels play a major role in the immediate and long term regulation of vascular smooth muscle function.1 The activity of these ion channels determines and regulates cell membrane potential, which, in turn, regulates the open state probability of voltage-gated Ca channels, Ca influx, and intracellular Ca . The concentration of intracellular Ca not only regulates the immediate contract...
