In postmortem brains of patients with major depression, the expression of corticotrophin-releasing factor (CRF) is enhanced and that of brain-derived neurotrophic factor (BDNF) decreased. In mice over-expressing neuronal CRF (an animal model for depression) the expression of urocortin 1 (Ucn1) in the non-preganglionic Edinger-Westphal nucleus (npEW) is(More)
Glial cell line-derived neurotrophic factor (GNDF) plays an important role in the development and synaptic plasticity of dopaminergic neurons, thus it could be an important therapeutic factor in Parkinson's disease. Results from candidate gene studies of GDNF in psychiatric disorders are contradictory. Moreover, the possible association between GDNF(More)
BACKGROUND Nefazodone is a 5-HT2-receptor antagonist and serotonin (5-HT) selective reuptake inhibitor. This study evaluates the safety and efficacy of nefazodone in patients with major depressive disorder (MDD) in comparison to imipramine and placebo treatments. It also compares two dose ranges of nefazodone to investigate its optimal dose range. METHOD(More)
BACKGROUND There is evidence indicating that serotonin uptake and density of 5-HT2A receptors are altered in brain regions of depressed suicide victims and in platelets of depressed suicidal subjects. The present investigation tested the hypothesis that these changes in the serotonergic system in depressed suicide victims are trait rather than state markers(More)
BACKGROUND Epigenetic mechanisms may be involved in the reprogramming of gene expression in response to stressful stimuli. This investigation determined whether epigenetic phenomena might similarly be associated with suicide/depression. METHODS The expression of DNA methyltransferase (DNMT) mRNA was assessed in several brain regions of individuals who had(More)
Clinical, epidemiological, neuroimaging and postmortem data all suggest schizophrenia is a neurodevelopmental disorder, and that synaptic disturbances might play a critical role in developing the disease. In 1982, Feinberg proposed that the schizophrenia might arise as a result of abnormal synaptic pruning. His hypothesis has survived 40years of accumulated(More)
The aim of this study was to investigate whether the previously observed adaptive changes in the monoaminergic receptors in post-mortem brains of depressed suicide victims are associated with alteration in some functional proteins involved in serotonergic neuronal signalling, namely PKC and GAP-43. Selected regions from ten brains of antidepressant-free(More)
UNLABELLED The clinical symptoms of major depression are paralleled by typical neurocognitive deficits. Our aim was to investigate the gender differences in neurocognitive impairment in patients with major depressive disorder. METHODS 96 patients with acute major depressive disorder meeting DSM-IV criteria participated in our study. Depression was(More)
Inter-relationships ordinarily exist between mRNA expression of GABA(A) subunits in the frontopolar cortex (FPC) of individuals that had died suddenly from causes other than suicide. However, these correlations were largely absent in persons that had died by suicide. In the present investigation, these findings were extended by examining GABA(A) receptor(More)
An intriguing novel pathophysiological insight into mood disorders is the notion that one's metabolic status influences mood. In rodents, cocaine- and amphetamine-regulated transcript (CART) and nesfatin-1/NUCB2 have not only been implicated in metabolism, but in the pathobiology of anxiety and depressive-like behaviour, however they have not previously(More)
