Upregulation of 5-hydroxytryptamine receptor signaling in coronary arteries after organ culture. [PDF]

PLoS ONE, 2014
5-Hydroxytryptamine (5-HT) is a powerful constrictor of coronary arteries and is considered to be involved in the pathophysiological mechanisms of coronary-artery spasm. However, the mechanism of enhancement of coronary-artery constriction to 5-HT during
