Molecular pathogenesis of Parkinson disease.
Parkinson disease (PD), the most common neurodegenerative movement disorder, is characterized by an extensive and progressive loss of dopaminergic neurons in the substantia nigra pars compacta. One of the pathological hallmarks of PD is the presence of Lewy bodies, intracellular inclusions of aggregated alpha-synuclein. Although the cause and pathogenesis of selective loss of dopamine neurons a...
متن کاملRole of iron in pathogenesis of Parkinson disease
Parkinson’s disease is one of the most frequent human neurodegenerations. Motor symptoms of Parkinson’s disease are the consequence of the destruction of nervous cells in the substantia nigra (SN), a small (about 500 mg) structure located deep in human brain. The concentration of iron in SN is comparable to that in liver and is equal to about 180 ± 60 ng/mg of wet tissue and the iron in SN is m...
متن کاملGlucocerebrosidase in the pathogenesis and treatment of Parkinson disease.
In PNAS, Sardi et al. describe that viral vector-mediated increase in glucocerebrosidase enzyme (GCase) activity can reverse synuclein-related pathological features and improve behavioral function in the D409V mouse model of Gaucher disease (GD) (1). This important study has several implications for our understanding of the pathogenesis of Parkinson disease (PD) and contributes toward the ratio...
متن کاملPolyamine pathway contributes to the pathogenesis of Parkinson disease.
The full complement of molecular pathways contributing to the pathogenesis of Parkinson disease (PD) remains unknown. Here we address this issue by taking a broad approach, beginning by using functional MRI to identify brainstem regions differentially affected and resistant to the disease. Relying on these imaging findings, we then profiled gene expression levels from postmortem brainstem regio...
متن کاملGlucocerebrosidase mutations and the pathogenesis of Parkinson disease.
Parkinson disease (PD) is the second most common neurodegenerative disease after Alzheimer disease with a lifetime risk in the UK population of almost 5%. An association between PD and Gaucher disease (GD) derived from the observation that GD patients and their heterozygous carrier relatives were at increased risk of PD. GD is an autosomal recessive lysosomal storage disorder caused by homozygo...
