Rotigotine treatment partially protects from MPTP toxicity in a progressive macaque model of Parkinson's disease
Combined 5-HT1A and 5-HT1B receptor agonists for the treatment of L-DOPA-induced dyskinesia.
TLDR
The results demonstrate the existence of a potent synergistic effect between 5- HT(1A) and 5-HT(1B) agonists in their ability to dampen l-DOPA-induced dyskinesia in the MPTP-treated macaques.
Dopamine Transporter Binding Is Unaffected by L-DOPA Administration in Normal and MPTP-Treated Monkeys
TLDR
Data indicate that L-DOPA does not induce modifications of DAT expression detectable by SPECT of by DAT binding autoradiography, suggesting that differences between clinical assessment and radiotracer imaging in clinical trials may not be specifically related to L- DOPA treatment.
Targeting 5-HT1A receptors in astrocytes to protect dopaminergic neurons in parkinsonian models
Different Alterations of Agonist and Antagonist Binding to 5-HT1A Receptor in a Rat Model of Parkinson's Disease and Levodopa-Induced Dyskinesia: A microPET Study.
TLDR
The data suggest that agonist and antagonist 5-HT1A receptor-binding sites are differently modified in Parkinson's disease and levodopa-induced dyskinesia and emphasize the need to characterize this state using agonist radiotracers in physiological and pathological conditions.
Effects of coincident 5-HT1A receptor stimulation and NMDA receptor antagonism on l-DOPA-induced dyskinesia and rotational behaviors in the hemi-parkinsonian rat
TLDR
Combined subthreshold doses of ±8-OH-DPAT and MK-801 dose-dependently decreased l-DOPA-induced AIMs without affecting rotations and indicate a functional interaction between 5-HT1AR and NMDAR that may improve pharmacological treatment of PD patients.
Early prenatal exposure to MPTP does not affect nigrostrial neurons in macaque monkey
TLDR
The ultimate effects of MPTP intoxication of a female macaque monkey, which unraveled to be pregnant after parkinsonism had developed, upon its fetus is reported, suggesting that early prenatal intoxication does not destroy nigrostriatal neurons, most likely because dopamine neurons had not developed yet when exposed to MPTP.
Serotonin 1A Receptors on Astrocytes as a Potential Target for the Treatment of Parkinson’s Disease
TLDR
The neuroprotective properties of astrocytes targeting certain molecules related to PD are summarized and new promising therapeutic strategies based on neuroprotection against oxidative stress and prevention of dopaminergic neurodegeneration are discussed.
Animal models of Parkinson's disease: a source of novel treatments and clues to the cause of the disease
TLDR
The MPTP‐treated primate model of PD, which closely mimics the clinical features of PD and in which all currently used anti‐parkinsonian medications have been shown to be effective, is undoubtedly the most clinically‐relevant of all available models.

Absence of MPTP-Induced Neuronal Death in Mice Lacking the Dopamine Transporter
TLDR
The results shed light on the degenerative process of dopamine neurons and suggest that individual differences in developing Parkinson's disease in human may be related to differences of uptake through the DAT of a yet unidentified neurotoxin.
Effects of Different Schedules of MPTP Administration on Dopaminergic Neurodegeneration in Mice
TLDR
Compared the effects of different schedules of injection of the same cumulative dose of MPTP, in mice, by measuring tyrosine hydroxylase immunoreactivity in the substantia nigra pars compacta, these mechanisms need to be better understood if chronic models of intoxication that replicate the evolution of human Parkinson's disease more precisely are to be developed.
Bax ablation prevents dopaminergic neurodegeneration in the 1-methyl- 4-phenyl-1,2,3,6-tetrahydropyridine mouse model of Parkinson's disease
TLDR
It is shown that the pro-apoptotic protein Bax is highly expressed in the SNpc and that its ablation attenuates SNpc developmental neuronal apoptosis, and it is suggested that targeting Bax may provide protective benefit in the treatment of Parkinson's disease.
Deleterious effects of minocycline in animal models of Parkinson's disease and Huntington's disease
TLDR
The histopathological outcome demonstrated that minocycline‐treated mice presented significantly more severe neuronal cell loss in the dorsal striatum in the 3‐nitropropionic acid mouse model of HD, and minocyCline blocked 3‐NP‐induced neurotoxicity at certain doses but not at higher doses.
Serotonin 5-HT1A agonist improves motor complications in rodent and primate parkinsonian models
TLDR
Drugs acting to stimulate 5-HT1A receptors could prove useful in the treatment of the motor response complications in parkinsonian patients.

Blockade of Microglial Activation Is Neuroprotective in the 1-Methyl-4-Phenyl-1,2,3,6-Tetrahydropyridine Mouse Model of Parkinson Disease
TLDR
It is shown that minocycline, an approved tetracycline derivative that inhibits microglial activation independently of its antimicrobial properties, mitigates both the demise of nigrostriatal dopaminergic neurons and the formation of nitrotyrosine produced by MPTP.
