Depression is a complex disorder related to chronic inflammatory processes, chronic stress changes and a hippocampal response. There is a increasing knowledge about the role of glial cells in nutrient supply to neurons, maintenance of synaptic contacts and tissue homeostasis within the CNS. Glial cells, viewed in the past as passive elements with a limited(More)
A diversity of high-affinity oligosaccharide ligands are identified for NKR-P1, a membrane protein on natural killer (NK) cells which contains an extracellular Ca(2+)-dependent lectin domain. Interactions of such oligosaccharides on the target cell surface with NKR-P1 on the killer cell surface are crucial both for target cell recognition and for delivery(More)
CNS, endocrine and immune systems share the same molecules: neurotransmitters, cytokines and hormones to communicate within and among each other. Depression is associated with abnormalities in the noradrenergic, serotonergic and dopaminergic neurotransmitter systems and reductions in the level of their precursors and metabolic turnover. Most of these(More)
OBJECTIVE Gonadotropin-releasing hormone (GnRH) antagonist combined with the human chorionic gonadotropin hormone (hCG) is commonly used in assisted reproduction techniques (ARTs) to induce controlled ovarian hyperstimulation (COH) and to synchronize oocyte maturation. While hCG is known to have immunomodulatory properties, we aimed to assess its effect on(More)
Agroclavine is a natural, clavine type of ergot alkaloid with D1 dopamine and a-adrenoceptor agonistic properties. We showed previously that in vitro agroclavine enhances natural killer (NK) cell activity, increases interleukin-2 and interferon-gamma production and prolongs the survival time of tumor-bearing mice. The aim of this study was 1) to test the(More)
BACKGROUND Our research compared whole pelvic (WP) and prostate-only (PO) 3-dimensional conformal radiotherapy (3DCRT) techniques in terms of the incidence and evolution of acute and late toxicity of the rectum and urinary bladder, and identified the PTV-parameters influencing these damages and changes in antitumor immune response. METHODS We analyzed 197(More)
The involvement of catecholamine receptors (alpha-adrenergic, D2-dopamine (DA)) was investigated in restraint stress influenced immune responses with concomitant changes of G-protein signal transduction. Impairment of the spleen morphology, TH1/TH2 cytokine network and natural killer (NK) cell function was observed. In vivo administration of specific(More)
OBJECTIVE Neurochemical approaches to antidepressant effects and depressive disorder are also focusing on G-protein coupled receptors (GPCR) and subsequent signalling. Trimeric G-proteins play a crucial role in transmembrane signalling, its amplification and processing. It is evident that immune system participates in antidepressant mode of action by(More)
OBJECTIVES Neurochemical studies on the etiopathogenesis of depression are also focusing on the transduction system beyond receptors. Trimeric G-proteins play a crucial role in the transmembrane signalling, signal amplification and intracellular processing. Abnormalities of G-protein levels are observed in subjects with depression, G-protein modulation is(More)
