Endothelial cells modulate the vasoinhibitory effect of NKY-722, a Ca2+ channel antagonist, in canine mesenteric arteries
Abstract
Modulation of the vasoinhibitory effect of NKY-722 by vascular endothelial cells was studied in canine mesenteric arteries. A high concentration of NKY-722 accumulated in the endothelium-intact arteries and its accumulation in endothelium-removed arteries was significantly less. The vasoinhibitory effect of NKY-722 in endothelium-intact arteries was significantly weaker than that in endothelium-removed arteries. These results suggest that endothelial cells can attenuate the vasoinhibitory effect of NKY-722.
