Article Abstract

Here we re-examine previous data that demonstrated lasting effects of the selective D1 receptor agonist SKF 38393, the selective D2 receptor agonist LY 171555, and of mixed SKF 39383 + LY 171555 upon striatal DA release. We demonstrate that the administration of mixed SKF 38393 + LY 171555 and of SKF 38393 administered alone induced similar time-course effects upon striatal DA release that showed significant parallel developments. We discuss these data in the light of the current literature and we suggest that D1 receptors could play a modulating role on the striatal DA activity and the release of DA in the caudate-putamen.

Dopaminergic system gains importance in homeostatic sleep regulation, but the role of different dopamine receptors is not well-defined. 72 h rat electrocorticogram and sleep recordings were made after single application of dopaminergic drugs in clinical use or at least underwent clinical trials. The non-selective agonist apomorphine evoked short pharmacological sleep deprivation with intense wakefulness followed by pronounced sleep rebound.

D1 Receptor Functional Asymmetry at Striatonigral Neurons: A Neurochemical and Behavioral Study in Male Wistar Rats.

J Neurosci Res

January 2025

Departamento de Fisiología, Biofísica y Neurociencias, Centro de Investigación y de Estudios Avanzados del Instituto Politécnico Nacional, Ciudad de Mexico, Mexico.

Lateralization of motor behavior, a common phenomenon in humans and several species, is modulated by the basal ganglia, a site pointed out for the interhemispheric differences related to lateralization. Our study aims to shed light on the potential role of the striatonigral D1 receptor in functional asymmetry in normal conditions through neurochemical and behavioral means. We found that D1 receptor activation and D1/D3 receptor coactivation in striatonigral neurons leads to more cAMP production by adenylyl cyclase in the striatum and GABA release in their terminals in the right hemisphere compared to the left.

The opioidergic and dopaminergic systems play an essential role in processing pain information in the nucleus accumbens (NAc). The present work examined the hypothesis that interaction between opioidergic and D1-like dopamine receptors in the NAc area may influence acute pain-related behaviors. One hundred sixty adult male Wistar rats unilaterally received different doses of the drug solution or vehicle.

Structural Insights into Dopamine Receptor-Ligand Interactions: From Agonists to Antagonists.

ACS Chem Neurosci

November 2024

Cancer Center and Department of Pharmacology and Toxicology, Medical College of Wisconsin, Milwaukee, Wisconsin 53226, United States.

This study explores the intricacies of dopamine receptor-ligand interactions, focusing on the D1R and D5R subtypes. Using molecular modeling techniques, we investigated the binding of the pan-agonist rotigotine, revealing a universal binding mode at the orthosteric binding pocket. Additionally, we analyze the stability of antagonist-receptor complexes with SKF83566 and SCH23390.

Cell firing between ON alpha retinal ganglion cells and coupled amacrine cells in the mouse retina.

Am J Physiol Cell Physiol

September 2024

School of Optometry, The Hong Kong Polytechnic University, Kowloon, Hong Kong, People's Republic of China.

Gap junctions are channels that allow for direct transmission of electrical signals between cells. However, the ability of one cell to be impacted or controlled by other cells through gap junctions remains unclear. In this study, heterocellular coupling between ON α retinal ganglion cells (α-RGCs) and displaced amacrine cells (ACs) in the mouse retina was used as a model.
