CSF Monoamine Metabolites and Cognitive Trajectory in Early Parkinson's Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Imaging and postmortem studies indicate that abnormalities in monoaminergic neurotransmission contribute to cognitive impairment in Parkinson's disease (PD). However, it remains uncertain if cerebrospinal fluid (CSF) monoamine metabolites can serve as biomarkers of cognitive decline in early PD.

Modulation of Adenylyl Cyclase Activity in Rat Striatal Homogenate by Dopaminergic Receptors

Journal of Pharmacological Sciences, 2008
We have characterized the modulation of adenylyl cyclase (AC) activity by ligands of dopaminergic receptors in rat striatal homogenate and compared the results with receptor-ligand binding affinities.

Pramipexole Upregulates Dopamine Receptor D2 and D3 Expression in Rat Striatum

Journal of Pharmacological Sciences, 2012
Randomized clinical trials have shown that pramipexole has an antidepressant effect in patients with Parkinson’s disease. We investigated the comparative efficacy of pramipexole toward dopamine receptor D2 and D3 expression in rat brain.

Preservation of dendritic D2 receptor transmission in substantia nigra dopamine neurons with age

Scientific Reports, 2023
Substantia nigra pars compacta (SNc) dopamine neurons are required for voluntary movement and reward learning, and advanced age is associated with motor and cognitive decline.

MPI‐Guided Photothermal Therapy of Prostate Cancer Using Stem Cell Delivery of Magnetotheranostic Nanoflowers

Advanced Functional Materials, EarlyView.
Tumor‐tropic human mesenchymal stem cells (hMSCs) were used as delivery vehicles for magnetotheranostic gold–iron oxide nanoflowers. Magnetic particle imaging of the iron component demonstrated widespread intratumoral distribution and sustained retention in contrast to injection of naked nanoflowers.

D1 Dopamine Receptor Activation Induces Neuronal eEF2 Pathway-Dependent Protein Synthesis

Frontiers in Molecular Neuroscience, 2020
Dopamine, alongside other neuromodulators, defines brain and neuronal states, inter alia through regulation of global and local mRNA translation. Yet, the signaling pathways underlying the effects of dopamine on mRNA translation and psychiatric disorders

Role of serotonin via 5-HT2B receptors in the reinforcing effects of MDMA in mice. [PDF]

PLoS ONE, 2009
The amphetamine derivative 3,4-methylenedioxymethamphetamine (MDMA, ecstasy) reverses dopamine and serotonin transporters to produce efflux of dopamine and serotonin, respectively, in regions of the brain that have been implicated in reward. However, the
