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 ...
Mutations in the leucine-rich repeat kinase 2 (LRRK2) gene cause late-onset, autosomal dominant familial Parkinson's disease (PD) and also contribute to idiopathic PD. LRRK2 mutations represent the most common cause of PD with clinical and neurochemical fe ...
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 ...
This study assessed the potential for functional and anatomical recovery of the diseased aged primate nigrostriatal system, in response to trophic factor gene transfer. Aged rhesus monkeys received a single intracarotid infusion of MPTP, followed one week ...
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 ...
The involvement of alpha-synuclein in familial forms of Parkinson's disease suggests a potential causative role in the pathogenesis. We have explored the possibility of generating animal models of Parkinson's disease by overexpressing alpha-synuclein in th ...
Parkinsonian handwriting is typically characterized by micrographia, jagged line contour, and unusual fluctuations in pen velocity. In this paper we present a computational model of handwriting generation that highlights the role of the basal ganglia, part ...
The interplay between dopamine and alpha-synuclein (AS) plays a central role in Parkinson's disease (PD). PD results primarily from a severe and selective devastation of dopaminergic neurons in substantia nigra pars compacta. The neuropathological hallmark ...
Parkinson's disease (PD) is a common progressive neurodegenerative disorder characterized clinically by the combination of motor symptoms like bradykinesia, tremor, rigidity and postural instability. The pathology of PD is related to the degeneration of do ...
