Dopamine (DA) is a neurotransmitter and chemical mediator, and DA receptors (particularly DRD1) are present on the majority of immune cells. The aim of this study was to investigate the effects of DA on lipopolysaccharide (LPS)-stimulated inflammatory responses in RAW264.7 A large body of evidence suggests that dietary n-3 polyunsaturated fatty acids (PUFAs), including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), contribute to a reduced inflammatory tone thereby lowering the risk for several chronic and degenerative diseases. Different mechanisms
Recent studies suggest that not only is constipation a clinical marker of premotor phase in Parkinson's Disease (PD), but is also correlated with the duration and severity. Some reports indicated that inflammatory from gut dysbiosis might be involved in the pathogenesis of PD, but the BACKGROUND
Endothelial barrier dysfunction severely compromises organ function after reperfusion. Because dopamine pretreatment improves hypothermia mediated barrier dysfunction, we tested the hypothesis that dopamine treatment of lung allografts positively affects tissue damage associated with
Depressed individuals suffer from effort-related motivational symptoms such as anergia and fatigue, which are resistant to treatment with many common antidepressants. While drugs that block dopamine transport (DAT) reportedly have positive motivational effects, DAT inhibitors such as cocaine and
A high-fat diet (HFD) can induce obesity and metabolic disorders that are closely associated with cognitive impairments, and the progression of several psychiatric disorders such as anxiety. We have previously demonstrated the anxiolytic-like effect of Gamma oryzanol (GORZ) in chronic OBJECTIVE
To observe the effect of repeated electroacupuncture (EA) on the expression of cannabinoid receptor-1 (CB 1) mrRNA and dopamine 1 receptor (D 1) mRNA in Nucleus Accumbens (NAC)-Caudate Nucleus (CN) region in inflammatory-pain rats, so as to study its underlying mechanism in
Inflammatory bowel diseases (IBD) are associated with altered neuronal regulation of the gastrointestinal (GI) tract and release of norepinephrine (NE). As sympathetic innervation of the GI tract modulates motility, blood flow, and immune function, changes in NE signaling may alter the risk of
Maternal inflammation during critical stages of gestation is thought to underlie the link between prenatal infection and several neurodevelopmental psychiatric disorders in the offspring, including schizophrenia. Increased activity of mesolimbic dopamine (DA) neurons, a hallmark of psychosis, is
The lateral hypothalamus (LH) plays a complicated role in the modulation of inflammatory pain. There are a number of connections between the LH and the hippocampus. This study evaluated the pain modulatory role of intra-CA1 dopamine receptors in LH chemical stimulation-induced antinociception in the
Pergolide, a dopamine agonist effective in the treatment of Parkinson's disease, has been shown to have anti-inflammatory activity in the carrageenan paw edema assay in rats at p.o. doses greater than or equal to 0.3 mg/kg. Studies were done to investigate the mechanism of action and to determine
In the present study, we synthesized and evaluated the anti-inflammatory effects of dopamine and alpha-lipoic acid (ALA) hybrid compounds, ALA-dopamine (HBU-199) and its acetylated derivative, ALA-acetyl dopamine (HBU-200), in BV2 microglia and RAW264.7 macrophage cells. HBU-199 and HBU-200 both
Activated neutrophil (PMN) adherence to vascular endothelium comprises a key step for both transendothelial migration and initiation of potentially deleterious release of PMN products. The biogenic amine, dopamine (DA), has been used for several decades in patients to maintain hemodynamic stability.
Parkinson's disease is a chronic neurodegenerative disease characterized by a significant loss of dopaminergic neurons within the substantia nigra pars compacta region and a subsequent loss of dopamine within the striatum. A promising avenue of research has been the administration of growth factors
Activation of peripheral P2X3 and P2X2/3 receptors by endogenous ATP is essential to the development of inflammatory hyperalgesia. We have previously demonstrated that this essential role of P2X3 and P2X2/3 receptors in the development of mechanical hyperalgesia induced by the inflammatory agent
