antidepressants/necrosis

The monoamine theory of depression proposes decreased bioavailability of monoamines, such as norepinephrine (NE), as the underlying cause of depression. Thus, the antidepressant efficacy of NE-reuptake inhibitors such as desipramine is attributed to increases in synaptic concentrations of NE. The

The present study documents a role for brain-derived tumor necrosis factor-alpha (TNF) in the mechanism of action of the antidepressant drug desmethylimipramine (desipramine). To establish this role, field stimulation and superfusion of rat hippocampal slices was employed to investigate the

The pleiotropic cytokine tumor necrosis factor-alpha (TNF) and alpha(2)-adrenergic receptor activation regulate norepinephrine (NE) release from neurons in the central nervous system. The present study substantiates the role of TNF as a neuromodulator and demonstrates a reciprocally permissive

In a wide range of human diseases of inflammatory nature like Crohn's disease, pathology is mediated in part by pro-inflammatory cytokines like tumor necrosis factor-alpha (TNF) or interferon-gamma. We show here that a commonly used generic antidepressant bupropion, in wide use worldwide to treat

Adiponectin, an adipose tissue-specific plasma protein, is involved in insulin sensitization and has anti-atherosclerotic properties, whereas tumor necrosis factor-alpha (TNF-alpha), a pro-inflammatory protein, plays important roles in inflammatory endothelial injury and atherosclerotic changes. It

Proton channels are gated by voltage and pH gradients, and play an important role in the microglial production of pro-inflammatory cytokines, which are known to be suppressed by antidepressants. In the present study we tested the hypothesis that cytokine inhibition by antidepressants is due to an

Tricyclic antidepressants (TCAs) of which imipramine is one, are commonly used in the treatment of depressive disorders and other forms of psychiatric illness. There have been many reports regarding the suppressive effects of TCAs on immune function. However, information is still limited regarding

Tumor necrosis factor-alpha (TNF alpha) and the alpha 2-adrenergic agonist clonidine regulate norepinephrine (NE) release from noradrenergic nerve terminals in the central nervous system (CNS). In the present study, superfusion and electrical field stimulation were applied to a series of rat

Selective Serotonin Reuptake Inhibitor antidepressants, such as fluoxetine (Prozac), have been shown to induce cell death in cancer cells, paving the way for their potential use as cancer therapy. These compounds are able to increase cytosolic calcium concentration ([Ca2+]cyt), but the involved

Presynaptic adrenergic functioning was coupled to cytokine sensitivity in order to further establish the mechanism of action of a tricyclic antidepressant drug. Antidepressant administration of desipramine to rats twice-daily for 2 weeks increased hippocampal TNF levels and transformed the

A growing body of evidence associates activation of immune system with depressive symptoms. Accordingly, pro-inflammatory cytokines, such as tumor necrosis factor-α (TNF-α), have been shown to play a pivotal role in the pathophysiology of depression. The aim of this study was to evaluate the

The olfactory bulbectomized (OB) rat has been developed as an animal model of depression and exhibits several behavioural and neurochemical characteristics that are qualitatively similar to those found in clinically depressed patients. In addition to the behavioural and neurochemical abnormalities

Bangpungtongsung-san (BTS) is a traditional Korean medicine consisting of 18 herbs, some which have antidepressant effects. Here, we used an animal model of reserpine-induced depression and lipopolysaccharide (LPS)-stimulated BV2 microglia to assess the antidepressant and anti-neuroinflammatory
