The regulation of dopamine and serotonin synthesis in rat brain striatal synaptosomes has been studied using HPLC methods. Noradrenaline was shown to markedly inhibit both the synthesis of dopamine and serotonin. The response of the synaptosomes to the concentrations of noradrenaline appeared to be biphasic, a very effective inhibition occurring at low concentrations (1-5 µm) and a relativ...

objective: the present study aimed to review the relapse rate in patients with schizophrenia treated with orally taken atypical agents (serotonin dopamine antagonists, sdas) and depot preparation of conventional (typical) antipsychotics. methods: in this historical cohort study, mean relapse per month (mrm) index, duration between initiation of antipsychotic treatment and the first relapse epis...

asthma is a chronic inflammatory disorder of the airways. the stress is a factor for asthma which indicates a disorder in the function of communicational mediators of nervous and  immunological systems  such  as  neurotransmitters.  a  study  indicated  that  blood serotonin concentration increases in asthmatic patients. other study indicates that one kind of the serotonin  receptors, named 5ht...

Abstract Indirect agonism has been invoked as part of the mechanism antipsychotic action at dopamine D 2/3 receptors, and more recently a salient neuropharmacological aspect serotonin 5‐HT 2A drug pimavanserin (Pim). We now comment on an article in this volume showing that Pim treatment attenuates deposition Aβ protein brain transgenic Alzheimer's disease model mice. may interfere with by shift...

Suicide is a complex and multifaceted public health issue that has been intensively studied to identify its contributing factors. Serotonin, neurotransmitter essential for affective regulation mood control, linked suicidal propensity. Understanding the relative contribution of serotonin’s genetic versus non-genetic influences development effective preventive measures, given etiology suicide inv...

Diabetic neuropathic pain, an important micro vascular complication in diabetes mellitus, has been recognized as one of the most difficult types of pain to treat. Lack of understanding of etiology involved, inadequate relief, development of tolerance and potential toxicity of classical anti-nociceptive agents warrants the investigation of newer agents to relieve this pain. The aim of the presen...

Serotonin(1A) receptors are important neurotransmitter receptors and belong to the superfamily of G-protein coupled receptors (GPCRs). Although it is an important drug target, the crystal structure of the serotonin(1A) receptor has not been solved yet. Earlier homology models of the serotonin(1A) receptor were generated using rhodopsin as a template. We have used two recent crystal structures o...

The serotonin 1A receptor is an important member of the G-protein coupled receptor family, and is involved in a variety of cognitive, behavioral, and developmental functions. None of the subtypes of G-protein coupled serotonin receptors have yet been purified to homogeneity from natural sources. We report here, for the first time, the solubilization of human serotonin(1A) receptors stably expre...

Serotonin (5-HT) plays an important role in the modulation of behavior across animal species. The serotonin 1A receptor (Htr1a) is an inhibitory G-protein coupled receptor that is expressed both on serotonin and non-serotonin neurons in mammals. Mice lacking Htr1a show increased anxiety behavior suggesting that its activation by serotonin has an anxiolytic effect. This outcome can be mediated b...
