Participation of 5-HT1-Like Receptors and 5-HT2 Receptors in Serotonin-Induced Contraction of Human Isolated Coronary Arteries 5-HT1-Like Receptors Resemble Cloned 5-HT1Dp Receptors
Background Serotonin may contract human large coronary arteries through two 5-hydroxtryptamine (5-HT) receptors, 5-HT1-like and 5 -HT2. These 5-HT1-like receptors resemble both cloned 5-HT1D receptor subtypes, 5-HT'1D, and 5 -HT1Ds. Although these subtypes have similar pharmacology, 5-HT1Dg receptors appear to have lower affinity for ketanserin than 5-HT1Di receptors. We assessed the relative p...
متن کاملEffects of Acute MDMA Intoxication on Mood and Impulsivity: Role of the 5-HT2 and 5-HT1 Receptors
UNLABELLED MDMA induces positive mood and increases impulse control during intoxication, but only a few studies on the neuropharmacological mechanisms underlying these processes have been conducted. It was hypothesized that pretreatment with 5-HT(1) and 5-HT(2) receptor blockers would prevent MDMA effects on mood and impulsivity. Subjects (N = 17) participated in a double-blind, placebo control...

متن کاملVariable participation of 5-HT1-like receptors and 5-HT2 receptors in serotonin-induced contraction of human isolated coronary arteries. 5-HT1-like receptors resemble cloned 5-HT1D beta receptors.
BACKGROUND Serotonin may contract human large coronary arteries through two 5-hydroxytryptamine (5-HT) receptors, 5-HT1-like and 5-HT2. These 5-HT1-like receptors resemble both cloned 5-HT1D receptor subtypes, 5-HT1D alpha and 5-HT 1D beta. Although these subtypes have similar pharmacology, 5-HT1D beta receptors appear to have lower affinity for ketanserin than 5-HT1D alpha receptors. We assess...
متن کاملBlock of 5-HT2 Receptors Enhances Hippocampal Long-Term Potentiation
The effect of endogenous serotonin on long-term potentiation (LTP) in region CAI was studied by blocking 5-HT2 receptors with ketanserin in rat hippocampal slices. Such a block significantly en-hanced long-term potentiation of the CAI population spike induced by high frequency stimulation of the schaffer collateral/ commissural pathway. This implies that serotonin acts on 5-HT2 receptors in CAI...
