Cell proliferation of neural progenitors in the subventricular zone (SVZ) of Parkinson disease (PD) patients and animal models is decreased. It was previously demonstrated that the neurotransmitter dopamine modulates cell proliferation in the embryonic brain. The aim of the present study was to analyze whether oral treatment with the dopamine receptor(More)
Treatment with pramipexole, a dopamine D(3)/D(2) receptor agonist, reduces depressive symptoms in patients suffering from Parkinson's disease. To test the putative antidepressant quality of pramipexole, its effects were assessed in one of the most attractive animal models of depression, the olfactory bulbectomized (OBX) rat. Two experiments studied the(More)
BACKGROUND Pramipexole exists as two isomers. The S(-) enantiomer is a potent D3/D2 receptor agonist and is extensively used in the management of PD. In contrast, the R(+) enantiomer is virtually devoid of any of the DA agonist effects. Very limited studies are available to characterize the pharmacological spectrum of the R(+) enantiomer of pramipexole. (More)
BACKGROUND The death of dopaminergic neurons in Parkinson's disease (PD) appears to have various causes, including oxidative stress, excitotoxicity, mitochondrial dysfunction (and associated apoptosis), ubiquitin/proteasomal dysfunction, and inflammation, any of which could in principle be the therapeutic target of a neuroprotective drug. The biology of(More)
Short-acting dopamine (DA) agonists are usually administered several times a day resulting in fluctuating plasma and brain levels. DA agonists providing continuous dopaminergic stimulation may achieve higher therapeutic benefit for example by alleviating nocturnal disturbances as well as early morning akinesia. In the present study continuous release (CR)(More)
