Heterogeneity of presynaptic serotonin receptors on sympathetic neurones in blood vessels.
Presynaptic serotonin (5-HT) receptors on the postganglionic sympathetic nerves, which mediate inhibition of noradrenaline release in blood vessels of various species and which interact with the presynaptic alpha 2-autoreceptors, are heterogeneous. In the rat vena cava, they are of the 5-HT1B subtype, in the pig coronary artery they belong to a novel, so far unknown class of 5-HT receptors, and in the human saphenous vein they could be classified as 5-HT1D. These results point to marked species differences and the need to carry out experiments in human vascular preparations. Presynaptic 5-HT receptors may be involved in the mechanism of action of the new antimigraine drug sumatriptan.
