While Parkinson's disease has been described nearly 200 years ago, the mechanisms leading to the degeneration of selectively vulnerable populations of neurons, such as dopaminergic neurons in the substantia nigra, remain mostly unknown. Our poor understand ...
Parkinson disease (PD) is a relatively common neurodegenerative disorder characterized by the progressive degeneration of dopaminergic neurons in the substantia nigra. About 5%-10% of PD cases are inherited. Mutations in the Parkin gene, which encodes a pr ...
Parkinson's disease is a neurodegenerative disorder characterized by the progressive loss of dopaminergic neurons in the substantia nigra. While sporadic in the majority of cases. PD-linked dominant mutations in the a-synuclein and LRRK-2 genes, and recess ...
Mitochondria are highly dynamic, multifunctional organelles. Aside from their major role in energy metabolism, they are also crucial for many cellular processes including neurotransmission, synaptic maintenance, calcium homeostasis, cell death, and neurona ...
The G2019S mutation in the leucine-rich repeat kinase 2 (LRRK2) gene is the most common genetic cause of Parkinson's disease (PD), accounting for a significant proportion of both autosomal dominant familial and sporadic PD cases. Our aim in the present stu ...
Animal models of human pathologies remain invaluable tools for unraveling disease mechanisms and evaluating potential therapeutic strategies. For a number of diseases, the lack of a reliable animal model represents an important limiting step towards the de ...
Alpha-synuclein is linked to both sporadic and familial forms of Parkinson's disease. The protein represents the major component of Lewy bodies – one of the hallmarks of the disease. Additionally, several point mutations and locus multiplications in the ge ...
In spite of partial success in treating Parkinson's disease by using ectopically placed grafts of dopamine-producing cells, restoration of the original neuroanatomical circuits, if possible, might work better. Previous evidence of normal anatomic projectio ...
Dysfunction of the central dopaminergic system is associated with neurodegenerative disorders and mental illnesses such as Parkinson's disease and schizophrenia. Patients suffering from these diseases were reported to exhibit altered immune functions compa ...
Loss of function of parkin, an ubiquitin ligase, is responsible for autosomal recessive juvenile parkinsonism (AR-JP). Parkin-associated endothelin receptor-like receptor (Pael-R) was identified as an authentic substrate of parkin and is thought to accumul ...
