The medial prefrontal cortex plays a key role in higher order cognitive functions like decision making and social cognition. These complex behaviors emerge from the coordinated firing of prefrontal neurons. Fast-spiking interneurons (FSIs) control the timing of excitatory neuron firing via somatic inhibition and generate gamma (30-100 Hz) oscillations. Therefore, factors that regulate how FSIs ...
Olanzapine, 2-methyl-4-(4-methyl-1-piperazinyl)-10H-thieno[2,3-b][1,5]benzodiazepine, is an atypical antipsychotic drug with a high affinity for serotonin (5HT2A/2C), dopamine (D1-4), muscarinic (M1-5), histamine H1, and α1-adrenergic receptors (1). Olanzapine is indicated for the treatment of patients with schizophrenia and psychosis of a schizoaffective nature. Olanzapine is well absorbed fol...
The serotonin receptor gene (5-HT2A) has been reported to be a susceptible factor in behavioral and psychological symptoms of dementia (BPSD) in Alzheimer's disease (AD). However, previous results were conflicting. We aim to investigate the association of 5-HT2A T102C with BPSD in AD using a meta-analysis. Studies were collected using PubMed, Web of Science, the Cochrane Library databases, Chin...
AIM The role of the Serotonin receptor 5HT2A and Serotonin transporter 5HTTLPR polymorphisms was suggested in the pathogenesis of depression and the therapeutic response to serotonergic drugs. The aim of this study was to find a possible association between polymorphisms of ins/del in the 5-HTT gene and T102C in the 5HTR2A gene and drug response for escitalopram and nortriptyline in depressed p...
BACKGROUND Position emission tomography (PET) imaging using [18F]-setoperone to quantify cortical 5-HT2A receptors has the potential to inform pharmacological treatments for geriatric depression and dementia. Prior reports indicate a significant normal aging effect on serotonin 5HT2A receptor (5HT2AR) binding potential. The purpose of this study was to assess the test-retest variability of [18F...
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...
We conducted a meta-analysis on the available data from studies investigating SERTs in ecstasy users and polydrug using controls. From 7 studies we compared data from 157 ecstasy users and 148 controls across 14 brain regions. The main effect suggested ecstasy/MDMA related SERT reductions (SMD=0.52, 95% CIs [0.40, 0.65]; Z=8.36, p<.01, I(2)=89%). A significant effect of subgroups (X(2)=37.41, d...
The pathogenesis of bipolar disorder may involve, at least in part, aberrations in serotonergic neurotransmission. Hence, serotonergic genes are attractive targets for association studies of bipolar disorder. We have reviewed the literature in this field. It is difficult to synthesize results as only one polymorphism per gene was typically investigated in relatively small samples. Nevertheless,...
Bipolar disorder is a mental illness with a lifetime prevalence of 2% and has a dramatic impact on quality of life. Mania is a distinct period of abnormal and sustained elevated, expansive, or irritable mood and increase in goal-directed activity or energy that lasts at least 1 week and is present for most of each day. Quetiapine is an atypical antipsychotic approved for the treatment of bipola...
