Ventral tegmental area (VTA) dopamine neurons play an important role in reward mechanisms of food intake, and VTA dopamine receptors exist on the terminal of glutamatergic and GABAergic neurons and regulate GABA and glutamate release. To our knowledge, there is no evidence to show that VTA D1 dopamine receptors play a role in regular chow intake. In this paper, the effect of SKF38393, a D1 rece...
objectives the cause of rheumatoid arthritis (ra) as a chronic inflammatory autoimmune disease is still unknown. it appears that both genetic and environmental factors play a role in its pathogenesis. recent studies reveal that in addition to the cns, immune cells synthesis neurotransmitters so that these catecholamines can regulate immune functions. the aim of this study is to evaluate the dop...
previous studies had reported that extracellular levels of ascorbic acid have modulatory effects on dopamine receptors. both ascorbic acid and dopamine receptor have an important role in learning and memory processes. however, the central interaction between ascorbic acid and dopamine d2 receptor on spatial learning and memory has not yet been elucidated. all experiments were carried out on mal...
introduction: spreading depression (sd) is a propagating wave of depolarization followed by depression of the neuroglial activities and can modulate extracellular dopamine concentrations in the neocortex. it has been shown that the dopaminergic system plays a role in migraine. sd has been suggested as a critical phenomenon in the pathophysiology of migraine. the aim of this study was to investi...
Dopamine is a neuromodulator and neurotransmitter responsible for number of physiological processes. Dysfunctions the dopamine metabolism signalling are associated with neurological psychiatric diseases. Here we report that in primary co-culture neurons astrocytes dopamine-induces calcium signal suppress spontaneous synchronous oscillations (SSCO) neurons. Effect on SSCO was dependent could be ...

Background & Objective: In previous studies, the effects of food restriction on the changes in immune responses and brain dopamine content have been determined. On the other hand, it has been shown that immune cells, in addition to dopamine production, also have dopamine receptors. The purpose of this study was to evaluate the effect of inhibition of D2 dopamine receptors on several functions o...
Introduction: Stimulation or inactivation of the lateral hypothalamus (LH) produces antinociception. Studies showed a role for the ventral tegmental area (VTA) in the antinociception induced by LH chemical stimulation through the orexinergic receptors. In this study, we assessed the role of intra-VTA dopamine D1 and D2 receptors in antinociceptive effects of cholinergic agonist, carbachol, m...
