5-Hydroxy-tryptophan for the treatment of l-DOPA-induced dyskinesia in the rat Parkinson's disease model

open access: yesNeurobiology of Disease, 2013
The serotonin system has recently emerged as an important player in the appearance of l-DOPA-induced dyskinesia (LID) in experimental models of Parkinson's disease, as it provides an unregulated source of l-DOPA-derived dopamine release in the dopamine ...

PET Studies of Cerebral Levodopa Metabolism: A Review of Clinical Findings and Modeling Approaches [PDF]

open access: yes, 2009
[18F]Fluoro-3,4-dihydroxyphenyl-l-alanine (FDOPA) was one of the first successful tracers for molecular imaging by positron emission tomography (PET), and has proven immensely valuable for studies of Parkinson’s disease.

From Cell‐Derived Vesicles to Hybrid Nanovectors: Biological Membranes as Functional Blueprints for Gene Delivery

open access: yesAdvanced Healthcare Materials, EarlyView.
Biologically derived and hybrid nonviral nanovectors are examined as distinct but convergent design approaches. Integrating synthetic components with biologically functionalized membranes allows efficient interactions with complex cellular environments.

The Multimodal Serotonergic Agent Vilazodone Inhibits L-DOPA-Induced Gene Regulation in Striatal Projection Neurons and Associated Dyskinesia in an Animal Model of Parkinson’s Disease

open access: yesCells, 2020
Levodopa (L-DOPA) treatment in Parkinson’s disease is limited by the emergence of L-DOPA-induced dyskinesia. Such dyskinesia is associated with aberrant gene regulation in neurons of the striatum, which is caused by abnormal dopamine release from ...

Determination of l-dopa using electropolymerized 3,3′,3″,3‴-tetraaminophthalocyanatonickel(II) film on glassy carbon electrode

open access: yes, 2007
Electropolymerized film of 3,3′,3″,3‴-tetraaminophthalocyanatonickel(II) (p-NiIITAPc) on glassy carbon (GC) electrode was used for the selective and stable determination of 3,4-dihydroxy-l-phenylalanine (l-dopa) in acetate buffer (pH 4.0) solution.

Sustainable Poly(Lactic Acid)/Graphene Oxide Bioelectronic Platform for Neurotransmitters Sensing and Tunable Stimulation of Astrocytes

open access: yesAdvanced Materials, EarlyView.
This work introduces sustainable PLA/graphene oxide bioelectronic interfaces featuring electrodes with tunable conductivity and strong electrocatalytic performance. These platforms were used to implement a new method for tuning astrocyte Ca2+ signaling and for the efficient detection of key biomarkers.

Keratin–Melanin Complexation Enables Robust, Delamination‐Resistant Feather‐Inspired Structural Color Coatings for Flexible and Curved Substrates

open access: yesAdvanced Materials Interfaces, EarlyView.
Providing mechanically robust structural color coating technology inspired by cooperative interactions in nature. The spatial arrangement of melanin particles within the keratin matrix generates angle‐independent structural colors. Diverse functional groups in keratin and melanin contribute to interparticle and substrate adhesion, resulting in the ...

L-DOPA-induced signaling pathways and neuroepigenetic mechanisms in experimental parkinsonism and dyskinesia

open access: yes, 2014
In patients with Parkinson’s disease (PD), the restoration of depleted striatal dopamine by chronic administration of its precursor, L-DOPA, results in the emergence of debilitating involuntary movements.
