A single-cell atlas of the human substantia nigra reveals cell-specific pathways associated with neurological disorders

open access: yesNature Communications, 2020
The substantia nigra is important in neurological disease, particularly movement disorders. Here the authors provide a single cell transcriptomic atlas for the human substantia nigra.

Substantia nigra and blood gene signatures and biomarkers for Parkinson’s disease from integrated multicenter microarray-based transcriptomic analyses [PDF]

open access: yesFrontiers in Aging Neuroscience
BackgroundParkinson’s disease (PD) is a complex, common neurodegenerative disorder with unclear etiology. The pathogenic hallmark is the death of dopaminergic neurons in the substantia nigra. PD diagnosis depends on clinical manifestation of symptoms but

Stable Dopamine-Signaling mRNA Co-Expression in the Substantia Nigra Is Deregulated in Pathological Conditions, but Not in Dopamine Transporter Knockout Rats [PDF]

open access: yesBiomolecules
Dopamine transporter (DAT) mutations are associated with neurological and psychiatric diseases, and DAT gene knockout in rats (DAT-KO) provides an opportunity to evaluate the DAT role in pathological conditions.

Striatal neuroinflammation promotes parkinsonism in rats [PDF]

open access: yes, 2008
The specific role of neuroinflammation in the pathogenesis of Parkinson's disease remains to be fully elucidated. By infusing lipopolysaccharide (LPS) into the striatum, we investigated the effect of neuroinflammation on the dopamine nigrostriatal ...

Application value of multiparametric MRI for evaluating iron deposition in the substantia nigra in Parkinson's disease

open access: yesFrontiers in Neurology, 2023
ObjectiveThis study aimed to investigate the application value of multi-parametric magnetic resonance imaging (MRI) in the diagnosis of iron deposition in the substantia nigra dense zone in Parkinson's disease (PD) and to evaluate the diagnostic value of

In vivo detection of substantia nigra and locus coeruleus volume loss in Parkinson's disease using neuromelanin-sensitive MRI: Replication in two cohorts.

open access: yesPLoS ONE, 2023
Patients with Parkinson's disease undergo a loss of melanized neurons in substantia nigra pars compacta and locus coeruleus. Very few studies have assessed substantia nigra pars compacta and locus coeruleus pathology in Parkinson's disease simultaneously

Illicit stimulant use is associated with abnormal substantia nigra morphology in humans. [PDF]

open access: yesPLoS ONE, 2013
Use of illicit stimulants such as methamphetamine, cocaine, and ecstasy is an increasing health problem. Chronic use can cause neurotoxicity in animals and humans but the long-term consequences are not well understood. The aim of the current study was to

Measurement of the adult human midbrain with transcranial ultrasound.

open access: yesPLoS ONE, 2021
BackgroundTranscranial sonography is increasingly used to aid clinical diagnoses of movement disorders, for example, to identify an enlarged area of substantia nigra echogenicity in patients with Parkinson's disease.ObjectiveThe current study ...

MRI T2 and T2* relaxometry to visualize neuromelanin in the dorsal substantia nigra pars compacta

open access: yesNeuroImage, 2020
Visualizing gradual changes in neuromelanin distribution within the substantia nigra is an important metric used to monitor the progression of Parkinsonism.

Neuromelanin Imaging and Dopaminergic Loss in Parkinson’s Disease

open access: yesFrontiers in Aging Neuroscience, 2016
Parkinson’s disease (PD) is a progressive neurodegenerative disorder in which the major pathologic substrate is a loss of dopaminergic neurons from the substantia nigra.
