Serotonin system implication in L-DOPA-induced dyskinesia: from animal models to clinical investigations [PDF]

open access: yes, 2014
In the recent years, the serotonin system has emerged as a key player in the induction of l-DOPA-induced dyskinesia (LID) in animal models of Parkinson's disease. In fact, serotonin neurons possess the enzymatic machinery able to convert exogenous l-DOPA

Dopamine neuronal loss contributes to memory and reward dysfunction in a model of Alzheimer's disease [PDF]

open access: yes, 2017
Alterations of the dopaminergic (DAergic) system are frequently reported in Alzheimer’s disease (AD) patients and are commonly linked to cognitive and non-cognitive symptoms. However, the cause of DAergic system dysfunction in AD remains to be elucidated.

Crystal structure and Hirshfeld surface analysis of 1-carboxy-2-(3,4-dihydroxyphenyl)ethan-1-aminium bromide 2-ammonio-3-(3,4-dihydroxyphenyl)propanoate

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2016
In the title molecular salt, C9H12NO4+·Br−·C9H11NO4, one of the dopa molecules is in the cationic form in which the α-amino group is protonated and the α-carboxylic acid group is uncharged, while the second dopa molecule is in the zwitterion form. The Br−

GABA storage and release in the medial globus pallidus in L-DOPA-induced dyskinesia priming

open access: yesNeurobiology of Disease, 2020
Levo-dihydroxyphenylalanine (L-DOPA) is the most effective treatment for Parkinson's disease; however, most patients develop uncontrollable abnormal involuntary movements known as L-DOPA-induced dyskinesia.

6R-L-erythro-5,6,7,8-Tetrahydrobiopterin and Dopamine Release

open access: yesPteridines, 1995
We previously reported that intracerebroventricular administration of 6R-L-erythro-5,6,7,8-tetrahydrobiopterin (6R-BJL), a cofactor for aromatic amino acid hydroxylases and nitric oxide synthase, induces an increase in DOPA levels (as an index of DA ...
