Dopamine D1-like receptors agonist SKF 38393 increases cFOS expression in the paraventricular nucleus of the hypothalamus-...
The present study indicates that activation of dopamine D1-like receptors by administration of SKF 38393 leads to dose-dependent (doses: 5, 10 and 20 mg/kg) increases in the expression of cFos proteins in the rat paraventricular nucleus of the hypothalamus (PVN). This effect was abolished by administration of SCH 23390, a dopamine D1-like receptor antagonist (0.5 and 1 mg/kg, given 30 min before SKF 38393--10 mg/kg), suggesting that the apparent effect is specific for activation of dopamine D1-like receptors. Expression of cFos after SKF 38393 (10 mg/kg) was observed in some, but not all, CRF-immunoreactive neurons, as well as in small portion of oxytocin- but not vasopressin-immunoreactive neurons (double-immunofluorescence experiments). There were also certain populations of nuclei that showed expression of cFos but did not co-localize with the above markers. We also found that both acute and repeated (once daily for 5 consecutive days) exposure to cocaine (25 mg/kg) attenuated the induction of cFos

Localization of dopamine receptor subtypes in systemic arteries | Pubblicazioni Scientifiche Unicam
Dopamine D1-D5 receptor protein immunoreactivity was investigated in different sized pial, renal and mesenteric artery branches using immunohistochemical techniques and anti-dopamine D1-D5 receptor protein antibodies. Faint dopamine D1 receptor protein immunoreactivity was observed in smooth muscle of tunica media of pial, renal and mesenteric artery branches. Dopamine D2 receptor protein immunoreactivity was located in the adventitia and adventitia-media border of pial and renal artery branches and to a lesser extent of mesenteric artery branches. No dopamine D3 receptor protein immunoreactivity was observed in pial and mesenteric arteries. In renal arteries a moderate dopamine D3 receptor immunoreactivity was detectable in the adventitia and adventitia-media border. A strong dopamine D4 receptor protein immunoreactivity displaying the same localization of dopamine D2 receptor protein was observed in pial and mesenteric arteries, but not in renal artery branches. Moderate dopamine D5 receptor ...

Differential effects of a selective dopamine D1-like receptor agonist on motor activity and c-fos expression in the frontal...
Molecular genetic studies suggest the dopamine D1 receptor (D1R) may be implicated in attention-deficit/hyperactivity disorder (ADHD). As little is known about the potential motor role of D1R in ADHD, animal models may provide important insights into this issue. We investigated the effects of a full and selective D1R agonist, SKF-81297 (0.3, 3 and 10 mg/kg), on motor behaviour and expression of the plasticity-associated gene, c-fos, in habituated young adult male Spontaneously Hypertensive Rats (SHR), the most commonly used animal model of ADHD, and Wistar-Kyoto (WKY; the strain from which SHR were derived). SHR rats were more behaviourally active than WKY rats after injection with vehicle. The 0.3 mg/kg dose of SKF-81297 increased motor behaviour (locomotion, sifting, rearing, and sniffing) in both SHR and WKY rats. Total grooming was also stimulated, but only in WKY rats. The same dose increased c-fos mRNA expression in the piriform cortex of both strains. The 3 mg/kg dose increased sifting and

Our initial studies were motivated by our recently reported findings that acutely applied cocaine can act through dopamine transporter blockade to enhance neurotransmitter activation of D2-like dopaminergic receptors and significantly enhance the magnitude of LTP evoked in the CA1 region of hippocampal slices (Thompson et al., 2005). We also noted that Gribkoff and Ashe (1984a, using paired stimuli while recording population spike responses) had previously concluded that exogenously applied dopamine could elicit a long-lasting attenuation of inhibition in the CA1. As outlined in the previous paragraph, we have found strong support for such a disinhibitory mechanism of cocaine actions using whole-cell voltage-clamp recordings of monosynaptic IPSCs evoked following stimulation of the stratum radiatum in the CA1 region. Activation of the D3 subtype of dopamine receptor appeared to mediate this effect because a D3-selective agonist could mimic the actions of cocaine, and pretreatment with a ...
Aberrant D1 and D3 Dopamine Receptor Transregulation in Hypertension | Hypertension
We have reported a physical interaction between D1 and D3 receptors in rat A10 aortic smooth muscle cells.23 In A10 and RPT cells from normotensive rats, D1 receptor stimulation with a D1-like agonist, fenoldopam, increases D1 receptor protein expression.23,25 In contrast, in RPT cells from SHRs, fenoldopam has no effect of D1 receptor expression.25 The current study extends our previous reports and has several novel observations. First, fenoldopam, via D1-like receptors, increases D3 receptor protein expression in RPT cells from WKY rats. Second, in these cells, D1 and D3 receptors co-immunoprecipitate, which is increased by D1-like receptor stimulation. Third, the aforementioned effects of D1-like receptor stimulation on D3 receptor protein and D1/D3 receptor co-immunoprecipitation are impaired in SHRs. Fourth, the D1-like receptor agonist, fenoldopam, increases D1 and D3 receptor protein expressions in human CASMCs. Fifth, activation of either D1 or D3 receptor relaxes the mesenteric artery ...

N2 - Activation of D2-like dopamine receptors in rods with quinpirole stimulates L-type calcium currents (ICa). This result appears inconsistent with studies showing that D2-like dopamine receptor activation diminishes rod signals in second-order retinal neurons. Since small reductions in [Cl-]i can inhibit photoreceptor ICa, we tested the hypothesis that enhancement of ICa, with the D2/D4 receptor agonist, quinpirole, increases calcium-activated chloride currents (ICl(Ca)) causing an efflux of Cl- from rods that would provide a negative feedback inhibition of ICa. In agreement with studies from Xenopus, quinpirole reduced rod input to second-order neurons of tiger salamander retina ...
Rosiglitazone Treatment Restores Renal Dopamine Receptor Function in Obese Zucker Rats | Hypertension
Earlier we have reported that the inhibitory effects of dopamine on NKA and NHE activities in proximal tubules of hyperinsulinemic obese rats were significantly reduced compared with lean rats. We also observed that the reduced inhibition of these transporters was associated with a significant reduction in D1 receptor number in proximal tubular membranes of obese rats. In the present study, we found that if plasma levels of insulin were lowered in obese rats, the ability of dopamine to inhibit the sodium transporters in proximal tubules was restored and membrane D1 receptor numbers were normalized to the level as in lean rats.. Dopamine, endogenously produced or exogenously infused, activates tubular D1 dopamine receptors, leading to the inhibition of sodium transporters, involving multiple second-messenger pathways and subsequently causes an increase in sodium excretion.1 There have been reports suggesting a negative correlation between renal dopaminergic function and plasma insulin ...
Dopamine- and cAMP-regulated phosphoprotein (DARPP-32) and dopamine DA1 agonist-sensitive Na+,K+-ATPase in renal tubule cells. ...
The cellular localization of DARPP-32, a dopamine- and cAMP-regulated phosphoprotein of Mr 32,000 that appears to mediate certain actions of dopamine in the mammalian brain by acting as an inhibitor of protein phosphatase 1, was studied in the kidney of several species. DARPP-32 mRNA and DARPP-32-like immunoreactivity were found in the cytoplasm of cells in the thick ascending limb of the loop of Henle. The specific dopamine DA1 agonist SKF 82526 caused a dose-dependent inhibition of Na+,K+-ATPase activity, which could be blocked by SCH 23390, a specific DA1 antagonist, and by PKI-(5-24) amide, a specific inhibitor of cAMP-dependent protein kinase. The results indicate that DA1 dopamine receptors and DARPP-32, an intracellular third messenger for dopamine, are part of the signal-transduction process for dopamine acting on renal tubule cells. ...

In this report we demonstrate for the first time that activation of the dopamine 1/5 receptors results in increased skeletal muscle cAMP, increased non-atrophying muscle mass and reduced atrophy-induced loss of muscle mass and force production. By using knockout mice to differentiate the effects of activation of the dopamine 1 receptor from that of the dopamine 5 receptor, we demonstrate that both the dopamine 1 and dopamine 5 receptors mediate the anti-atrophy effects of the dopamine 1/5 receptor selective agonist SKF 81297. Genetic removal of the dopamine 1 receptor (with maintenance of the dopamine 5 receptor) results in a complete loss of the SKF 81297 mediated EDL mass/force preservation, data consistent with the idea that the dopamine 1 receptor mediates the effects of SKF 81297. In contrast, genetic removal of the dopamine 5 receptor (with maintenance of the dopamine 1 receptor) resulted in a partial loss of SKF 81297 mediated EDL mass/force preservation, data that is inconsistent with ...

AU - Wiens, Brenda L.. AU - Nelson, Cole S.. AU - Neve, Kim A.. PY - 1998/8. Y1 - 1998/8.

We used rat D(2S) dopamine receptor mutants, each containing a serine-toalanine substitution (S193A, S194A, S197A), to investigate the mechanism through which these residues affect activation of the receptor. Activation of the mutant receptor S194A was abolished in an agonist-dependent manner, such that dopamine no longer inhibited cAMP accumulation in C6 glioma cells or activated G protein-regulated K+ channels in Xenopus laevis oocytes, whereas the efficacy of several other agonists was unaffected. Dihydrexidine did not inhibit cAMP ...
ASSA14-03-08 Gastrin and D1 Dopamine Receptor Interact to Induce Natriuresis and Diuresis | Heart
Result Gastrin infusing WKY rats via renal artery induced natriuresis and diuresis, which was blocked in the presence of CI988, a gastrin receptor blocker. Similarly, effect hereinbefore of fenoldopam, a D1-like receptor agonist, was blocked by D1-like receptor antagonist, SCH23390, indicating gastrin and fenoldopam play natriuretic and diuretic effect through individual receptors. Lower dosages of gastrin or fenoldopam failed to induce natriuresis and diuresis alone, while putting together induced the effects. The above-mentioned effects were lost in SHRs. Natriuresis and diuresis was partially blocked by SCH23390 or CI988, indicating the interaction between gastrin and D1-like receptor. Stimulation of either receptor increased the expression of the other and inhibited Na+-K+-ATPase activity, while the inhibitory effect of Na+-K+-ATPase activity was partially blocked through its corresponding receptors due to respective existence of SCH23390 and CI988.. ...
Glutamate Counteracts Dopamine/PKA Signaling via Dephosphorylation of DARPP-32 Ser-97 and Alteration of Its Cytonuclear...
The interaction of glutamate and dopamine in the striatum is heavily dependent on signaling pathways that converge on the regulatory protein DARPP-32. The efficacy of dopamine/D1 receptor/PKA signaling is regulated by DARPP-32 phosphorylated at Thr-34 (the PKA site), a process that inhibits protein phosphatase 1 (PP1) and potentiates PKA action. Activation of dopamine/D1 receptor/PKA signaling also leads to dephosphorylation of DARPP-32 at Ser-97 (the CK2 site), leading to localization of phospho-Thr-34 DARPP-32 in the nucleus where it also inhibits PP1. In this study the role of glutamate in the regulation of DARPP-32 phosphorylation at four major sites was further investigated. Experiments using striatal slices revealed that glutamate decreased the phosphorylation states of DARPP-32 at Ser-97 as well as Thr-34, Thr-75, and Ser-130 by activating NMDA or AMPA receptors in both direct and indirect pathway striatal neurons. The effect of glutamate in decreasing Ser-97 phosphorylation was mediated by

In the current study we examined the relationship between dopamine D2 signaling and prefrontal representations in humans. Dopamine has long been suggested to play a fundamental role in prefrontal functions (Miller and Cohen, 2001; Robbins and Arnsten, 2009; DArdenne et al., 2012). For instance, dopamine applied to the primate prefrontal cortex enhances the signal-to-noise ratio of pyramidal neurons representing task-relevant stimuli (Jacob et al., 2013). However, effects of dopamine on prefrontal function seem to be receptor specific, as D1- and D2-specific agents differentially affect the activity patterns of prefrontal neurons (Seamans et al., 2001). For instance, a low dose of a D1 agonist applied to the prefrontal cortex sharpens the spatial tuning of task-sensitive neurons in a spatial working memory task (Vijayraghavan et al., 2007), and blocking prefrontal D1 receptors impairs learning of visuomotor associations (Puig and Miller, 2012). In contrast, D2-receptor antagonists impair ...

Dopamine D1 and D2 Receptors in Chronic Mild Stress: Analysis of Dynamic Receptor Changes in an Animal Model of Depression Using In Situ Hybridization and Autoradiography Depression is a multifaceted illness that involves altered monoamine neurotransmission. Many monoamine receptor subtypes (e.g., dopamine D1 and D2) demonstrate altered expression levels in depressed patients and animal models of depression. Currently, there are an increasing number of molecular and biochemical studies on the mechanism of stress resilience. In this chapter, we describe a chronic mild stress (CMS) procedure along with in situ hybridization and autoradiography protocols to study changes in brain dopamine receptor expression of rats subjected to CMS. Chronic mild stress procedure (CMS) is one of few behavioral animal models of depression, and this model has good construct, face, and predictive validity. Moreover, approximately 30 % of rats exposed to stress regimen are stress resilient. There are numerous ...

How to Supercharge Your Dopamine Levels Naturally and Never Feel Less Anxious Again - Truth Revolution
The opiates bind to the opiate receptors in the brain, increasing a dopamine release, but once gone, there is an ever-increasing need for more opiate (or other drug) to induce the same dopamine-high. This is what causes drug addicts to resort to ever increasing, negative behaviors to get their next fix. The dopamine high is that desirable.. In experiments conducted with mice, when the same nerve bundle that causes an opiate release was stimulated when they pressed a lever, the mice, left to their own devices, would press the lever thousands of times in an hour, due to the pleasurable feelings the dopamine would induce. A later experiment (conducted unethically on a human being) showed a similar response. Over the course of three hours, a person would press a button which triggered a dopamine dump thousands of times to get an immense emotional boost.. We get little dopamine dumps in our brains with less destructive behaviors - like making money, having sex, and even winning a video game, but ...

Frontiers | Dopamine D4 receptor polymorphism and sex interact to predict childrens affective knowledge | Psychology
Affective knowledge, the ability to understand others emotional states, is considered to be a fundamental part in efficient social interaction. Affective knowledge can be seen as related to cognitive empathy, and in the framework of theory of mind (ToM) as affective ToM. Previous studies found that cognitive empathy and ToM are heritable, yet little is known regarding the specific genes involved in individual variability in affective knowledge. Investigating the genetic basis of affective knowledge is important for understanding brain mechanisms underlying socio-cognitive abilities. The 7-repeat (7R) allele within the third exon of the dopamine D4 receptor gene (DRD4-III) has been a focus of interest, due to accumulated knowledge regarding its relevance to individual differences in social behavior. A recent study suggests that an interaction between the DRD4-III polymorphism and sex is associated with cognitive empathy among adults. We aimed to examine the same association in two childhood age groups.

Basal Ganglia Paths Support Acute vs. Automated Execution, Not Movement vs. Stopping[v2] | Preprints
The basal ganglia (BG) are a central component of the brain, crucial to the initiation, execution and learning of adaptive actions. The BG are the major site of the action of dopamine. An important aspect of the BG architecture is the existence of two paths, direct and indirect, having different projection targets and dopamine receptor expression. To understand the BG, dopamine, and related disorders, it is imperative to understand the two paths. The standard account used in neuroscience research for decades posits that the role of the direct path is to support movements, while that of the indirect path is to suppress unselected or completed movements. This account is contradicted by converging evidence. Here, we explain why the arguments supporting the standard account are flawed, and present a new account, in which the role of the indirect path is completely opposite: to support automated execution.
