Anxiolytic effects of 5-HT₁A receptors and anxiogenic effects of 5-HT₂C receptors in the amygdala of mice.
The aim of the present study is to test a hypothesis that 5-HT(1A) and 5-HT(2C) receptors in the amygdala play an important role in the regulation of anxiety behaviors. We examined alterations in anxiety-like behaviors after manipulation of the expression of 5-HT(1A) and 5-HT(2C) receptors in the amygdala using recombinant adenovirus approaches. Recombinant adenoviruses containing a 5-HT(1A) pr...
متن کاملConservation of 5-HT1A receptor-mediated autoinhibition of serotonin (5-HT) neurons in mice with altered 5-HT homeostasis
Firing activity of serotonin (5-HT) neurons in the dorsal raphe nucleus (DRN) is controlled by inhibitory somatodendritic 5-HT1A autoreceptors. This autoinhibitory mechanism is implicated in the etiology of disorders of emotion regulation, such as anxiety disorders and depression, as well as in the mechanism of antidepressant action. Here, we investigated how persistent alterations in brain 5-H...
متن کاملTitle The 5 - HT 1 A receptor and 5 - HT transporter in temporal lobeepilepsy
Objective: To study 5-HT transport and 5-HT1A receptors in temporal lobe epilepsy (TLE) and depression. Methods: Thirteen patients had PET with [11C]DASB for 5-HTT and [18F]FCWAY for 5-HT1A receptor binding, MRI, and psychiatric assessment. Sixteen healthy volunteers had [11C]DASB, 19 had [18F] FCWAY, and 6 had both PET studies. We used a reference tissue model to estimate [11C]DASB binding. [1...
متن کاملContribution of the 5-HT(1B) receptor to hypoxia-induced pulmonary hypertension: converging evidence using 5-HT(1B)-receptor knockout mice and the 5-HT(1B/1D)-receptor antagonist GR127935.
5-Hydroxytryptamine (5-HT)(1B) receptors mediate contraction in human pulmonary arteries, and 5-HT(1B) receptor-mediated contraction is enhanced in pulmonary arteries from hypoxic rats. Here we further examine the role of this receptor in the development of pulmonary hypertension (PHT) by examining (1) the effects of a 5-HT(1B/1D)-receptor antagonist (GR127935) on hypoxia-induced PHT (CHPHT) in...
متن کاملDopamine release induced by atypical antipsychotics in prefrontal cortex requires 5-HT(1A) receptors but not 5-HT(2A) receptors.
Atypical antipsychotic drugs (APDs) increase dopamine (DA) release in prefrontal cortex (PFC), an effect probably mediated by the direct or indirect activation of the 5-HT(1A) receptor (5-HT(1A)R). Given the very low in-vitro affinity of most APDs for 5-HT(1A)Rs and the large co-expression of 5-HT(1A)Rs and 5-HT(2A) receptors (5-HT(2A)Rs) in the PFC, this effect might result from the imbalance ...
