Summary
The receptor which mediates the contraction elicited by 5-hydroxytryptamine (5-HT, serotonin) in human pial arterioles has been characterized. The overall rank order of agonist potency was 5-carboxamidotryptamine (5-CT) > 5-HT > RU 24969 = α-CH3-5-HT = methysergide ≫ MDL 72832 = 2-CH3-5-HT ≫ 8-OH-DPAT, with maximal contractile responses being comparable for most agonists. An excellent correlation was obtained for the vascular potencies of agonists and their published affinities for rat cortical 5-HT1B (r = 0.86; p < 0.01) and human caudate 5-HT1D (r = 0.98; p < 0.005) binding sites. The 5-HT-induced contraction was not blocked by 5-HT 1B (propranolol), 5-HT1C (mesulergine, mianserin), 5-HT2 (ketanserin, mianserin, MDL 72832) or 5-HT3 (MDL 72222) antagonists. In contrast, methiothepin (non-selective 5-HT1-like/5-HT2) and metergoline (non-selective 5-HT1D) were potent inhibitors of this vasomotor effect with respective pA2 values on the order of 8.51 and 7.06. A correlation analysis between the overall agonist/antagonist vascular potencies and their reported potencies for 5-HT-mediated second messenger effects; i.e. adenylate cyclase activity (5-HT1A, 5-HT1B or 5-HT1D-coupled effect) or inositol phosphate metabolism (5HT1C-mediated response), showed a positive correlation for 5-HT1B (r = 0.89; p < 0.001) and 5-HT1D (r = 0.90; p < 0.001) functional receptors. Our study suggests that a 5-HT1-like receptor, most likely of the 5-HT1D subtype, mediates the vasoconstriction to 5-HT in human brain vessels.
