Cholecystokinin (CCK) is one of the most abundant neuropeptides in the brain. It is found in the highest levels in cortical and limbic structures and also in the basal ganglia. Two subtypes of CCK receptors have been described in the brain and gastrointestinal tissues. CCK(A) (alimentary subtype) receptors are mainly located in the gastrointestinal tract,(More)
Alterations in the immune system may have importance for the pathophysiology of depression. Several studies have linked increased production of pro-inflammatory cytokines to depression and depressive symptoms. There is growing evidence that antidepressive treatment may influence the production of pro-and anti-inflammatory cytokines. In the present study we(More)
The role of the serotonin (5-HT) system in the neurobiology and treatment of panic disorder (PD) remains unproven. Previously we detected lower brain 5-HT transporter (SERT) availability in PD, but the findings were preliminary and mainly limited to female patients. The aim of this study was to assess non-displaceable brain SERT binding potential (BP (ND))(More)
OBJECTIVE In the present investigation we screened a large number of single nucleotide polymorphisms in the genes relevant to the neurobiology of anxiety for their association with panic disorder (PD). METHODS The study sample included 127 patients with PD and 146 healthy control subjects. Using Arrayed Primer Extension technology we genotyped 90(More)
A sample of 855 rural adult inhabitants of Udmurtia was interviewed by means of the Composite International Diagnostic Interview (CIDI) in order to investigate the incidence and prevalence of mood disorders. Depression affected 30.5% of the population according to ICD-10, and 22% according to DSM-III-R over a 12-month period. Depressive disorders were more(More)
Eight patients with panic disorder were administered 20 micrograms of cholecystokinin tetrapeptide (CCK-4) before and after 8 weeks of treatment with the selective serotonin reuptake inhibitor (SSRI) citalopram. All patients responded to treatment by showing a significant general improvement and reaching a panic-free state for 2 weeks. At the rechallenge(More)
Studies so far have provided contradictory results on immune system markers during use of antidepressants. There are no data on changes in immune parameters after treatment augmentation. The present study aimed to clarify whether the addition of bupropion in escitalopram-resistant patients with major depression causes changes in the immune system and(More)
The purpose of this case-control genetic association study was to explore potential relationships between polymorphisms in the limbic system-associated membrane protein (LSAMP) gene and mood and anxiety disorders. A total of 21 single-nucleotide polymorphisms (SNPs) from the LSAMP gene were analyzed in 591 unrelated patients with the diagnoses of major(More)
The effects of cholecystokinin tetrapeptide (CCK-4) on respiratory resistance were studied in 14 healthy volunteers by the registration of slow vital capacity and flow volume loop during forced respiration test. The administration of CCK-4 (50 micrograms) was performed in a double-blind and placebo-controlled design. Injections of CCK-4 induced prominent(More)
There is strong evidence for the importance of the serotonin (5-HT) system in the neurobiology of panic disorder (PD); however, the exact role of this system remains unclear. The 5-HT transporter (5-HTT) is a key element in 5-HT neurotransmission. The current study aimed to investigate the binding of 5-HTT in the brain of patients with PD. We used(More)
