Exposure to psychosocial stress is known to precipitate the emergence of stress related psychiatric disorders such as depression and anxiety. While mechanisms by which this occurs remain largely unclear, recent evidence points towards a causative role for inflammation. Neurotransmitters, such as

Bupropion attenuates morphine tolerance and dependence: Possible role of glutamate, norepinephrine, inflammation, and oxidative stress.

Morphine - the main pillar of nociceptive pain management - systemic use is associated with development of tolerance and dependence. Tolerance and dependence lay a heavy burden in clinical pain management settings. An added weight to this dilemma is that effective, safe, and tolerable

Corticosteroids (CS) and norepinephrine (NE) support each other's biological effects. Thus, deficiency of cortisol and reduced synovial sympathetic innervation (SSI) may be proinflammatory in rheumatoid arthritis (RA). This study tested the anti-inflammatory cooperativity of CS and NE in human RA

OBJECTIVE Traumatic brain injury is frequently accompanied by a systemic inflammatory response. Systemic inflammation was associated with cerebral hyperperfusion uncoupled to global oxygen metabolism in ovine head trauma. The present study investigated the cerebral effects of cerebral perfusion

The toxicity of tumor necrosis factor-alpha upon cholinergic neurons within the nucleus basalis and the role of norepinephrine in the regulation of inflammation: implications for Alzheimer's disease.

Inflammation and reduced forebrain norepinephrine are features of Alzheimer's disease that may interact to contribute to the degeneration of specific neural systems. We reproduced these conditions within the basal forebrain cholinergic system, a region that is vulnerable to degeneration in

Differences between the Lewis and Sprague-Dawley rats in chronic inflammation induced norepinephrine sensitivity of cutaneous C-fiber nociceptors.

We investigated whether there are any differences between the Lewis and Sprague-Dawley (SD) rats in chronic inflammation-induced norepinephrine (NE) sensitivity of nociceptors. Activities of C-fiber nociceptors innervating rat hairy hindpaw skin were recorded in an in vitro skin-nerve preparation.

Norepinephrine-dependently released Dr fimbriae of diffusely adhering Escherichia coli strain IH11128 promotes a mitogen-activated protein kinase ERK1/2-dependent production of pro-inflammatory cytokine, IL-8 in human intestinal Caco-2/TC7 cells.

The diffusely adhering Escherichia coli (Afa/Dr DAEC) are associated with recurrent urinary tract infections in adults as well as with diarrheal disease in infants. We previously demonstrated that in wild-type strain IH11128, the Dr fimbriae is released in the extracellular medium in response to

Inhibition of microglial inflammatory responses by norepinephrine: effects on nitric oxide and interleukin-1beta production.

BACKGROUND: Under pathological conditions, microglia produce proinflammatory mediators which contribute to neurologic damage, and whose levels can be modulated by endogenous factors including neurotransmitters such as norepinephrine (NE). We investigated the ability of NE to suppress microglial

OBJECTIVE The use of cyclooxygenase-2 (COX-2) inhibitors has been reported to be associated with detrimental vascular events. The aim of our study was to evaluate the role of COX-2 activity in the control of human vascular tone under inflammatory conditions. RESULTS Using organ bath experiments, the

Aortic hyporeactivity to norepinephrine induced by lipopolysaccharide in cirrhotic rats: beneficial effects of a non-steroidal anti-inflammatory drug coupled with a nitric oxide donor.

OBJECTIVE Cirrhosis is associated with a hyperdynamic syndrome and arterial vasodilation that is related to nitric oxide (NO) synthase 3 overactivity. Septic shock is frequently associated with cirrhosis and with a vascular induction of NO synthase 2. The aims of this study were to compare the

Norepinephrine and arginine vasopressin increase hepatic but not renal inflammatory activation during hemodynamic resuscitation in a rodent model of brain-dead donors.

OBJECTIVE Hypotension that occurs after brain death causes a deterioration in organ function, which in turn restricts the number of organs that can be retrieved and leads to graft dysfunction. The correction of hypotension by the administration of norepinephrine increases the number of organs

Duloxetine (DXT), a potent serotonin/norepinephrine reuptake inhibitor, is widely used in the treatment of major depressive disorder. In the present study, we examined the effects of DXT treatment on seizure behavior and excitotoxic neuronal damage in the mouse hippocampal CA3 region following

OBJECTIVE Density of sympathetic nerve fibers in synovial tissue was lower in patients with rheumatoid arthritis (RA) compared to those with osteoarthritis (OA). This was accompanied by norepinephrine (NE) release from synovial tyrosine hydroxylase positive cells (TH+ cells). We investigated the

Peripheral injection of lipopolysaccharide enhances expression of inflammatory cytokines in murine locus coeruleus: possible role of increased norepinephrine turnover.

Cytokines and catecholamines are known to constitute a significant portion of the regulatory neuroimmune networks involved in maintaining homeostasis in the central nervous system (CNS). Although we have already reported an increase in norepinephrine (NE) turnover within the locus coeruleus (LC) at
