New trends in the neurobiology and pharmacology of affective disorders.
Journal Title: Pharmacological Reports - Year 2013, Vol 65, Issue 6
Abstract
Although depression is a common disorder that is often resistant to pharmacotherapy, its pathophysiology has remained elusive. Since the early 1950s, when the first antidepressants were introduced, i.e., the non-selective MAO inhibitors and tricyclic drugs, a number of hypotheses describing ethiopathogenesis of depression and antidepressant drug action have been formulated. The Institute of Pharmacology, the Polish Academy of Sciences has performed experimental and clinical research focused on the pathophysiology of depression and the mechanisms of action of antidepressant drugs for over 40 years. Our results from this period have significantly contributed to understanding the complex mechanisms of antidepressant drug actions and new pathways that underpin the pathophysiology of depression. Most of these theories are based on the finding that the chronic administration of antidepressants leads to adaptive changes in pre- and post-synaptic monoaminergic and glutamatergic neurotransmission as well as to alterations in gene transcription and immune-inflammatory and neurotrophic factors, resulting in neuroplastic changes in the brain. Taking into account the functional interdependence of the neuronal, hormonal and immunologic systems, we propose neurodevelopmental and neuroimmune theories for affective disorders. Moreover, commonalities have been documented for the pathomechanisms of depression and neurodegenerative and metabolic disorders as well as drug dependence. The aim of this special issue is to briefly present the major research contributions and the new research directions of the Institute of Pharmacology, the Polish Academy of Sciences with respect to the neurobiology of affective disorders and the mechanisms of action of marketed and new putative antidepressant drugs.

Accelerated thrombus lysis in the blood of plasminogen activator inhibitor deficient mice is inhibited by PAI-1 with a very long half-life.
Patients with defective plasminogen activator inhibitor protein (PAI-1) or with PAI-1 deficiency can experience hemorrhage as a result of a hyperfibrinolysis. In these patients, a normal thrombus forms, but endogenous ly...

Background: Our previous studies in a group of arylpiperazine derivatives of 1,3-dimethyl-3,7-dihydro-purine-2,6-diones, aimed at chemical diversification of the purine-2,6-dione by introduction of hydrophobic substituen...
In vitro effects of serotonin and noradrenaline reuptake inhibitors on human platelet adhesion and coagulation.
Background: Although several studies show that there is an increased risk of bleeding events during antidepressant treatment with selective serotonin reuptake inhibitors (SSRIs), few studies show direct effects in vitro...
Gingko biloba extract diminishes stress-induced memory deficits in rats.
Exposure to chronic restraint stress in rats and psychosocial stress in humans has been shown to alter cognitive functions such as learning and memory and has been linked to the pathophysiology of mood and anxiety disord...
Involvement of adenosine receptors in dizocilpine-induced motor activity in mice.
The effect of adenosine receptor ligands on dizocilpine-induced locomotion was studied in mice. Dizocilpine-induced hyperactivity (0.1 mg/kg ip) in mice was antagonized by all adenosine receptor agonists: CPA - A(1) rece...
