Recently, we confirmed the presence of enhanced neural reconstruction in Parkinson's disease and in an animal model of Parkinson's disease based on increased polysialic acid-like immunoreactivity. Changes in neurogenesis often appear parallel to changes in angiogenesis. Moreover, both these processes share similar modulating factors, like vascular(More)
Parkinson's disease (PD), one of the most common human neurodegenerative diseases, is characterized by the loss of dopaminergic neurons in the substantia nigra of the midbrain. PD is a complex disorder with multiple genetic and environmental factors influencing disease risk. To identify susceptible genes for sporadic PD, we performed case-control(More)
The involvement of the central nervous system (CNS) in Sweet's syndrome (acute febrile neutrophilic dermatosis) is rare. We report a 47-year-old woman who presented with acute encephalitis and was subsequently diagnosed as having Sweet's syndrome. She developed altered consciousness following fever and erythematous skin plaques in the extremities.(More)
A 62-year-old man complained of resting tremor and posture tremor. In spite of presence of the tremor, other parkinsonian component was very mild. [(11)C]2β-carbomethoxy-3β-(4-fluorophenyl)-tropane ([(11)C]CFT) PET showed asymmetrical reduction of the uptake and [(11)C]raclopride PET showed slightly increased uptake in the striatum. Although he was(More)
BACKGROUND Depression, parkinsonism, and hypoventilation (Perry syndrome) or familial motor neuron disease have been linked to mutations in dynactin P150(Glued) (DCTN1). METHODS We employed genealogic, clinical, neurologic, and MRI investigations, as well as analysis of genes implicated in parkinsonism. Cellular transfection, immunocytochemistry, and(More)
Oxidative stress including DNA oxidation is implicated in Parkinson’s disease (PD). We postulated that DNA repair enzymes such as 8-oxoguanosine DNA glycosylase (OGG1) are involved in the PD process. We performed immunohistochemical and biochemical studies on brains of patients with PD and those of patients with progressive supranuclear palsy (PSP) and(More)
There is ample evidence for the involvement of oxidative stress in mitochondrial DNA damage and repair mechanisms in Parkinson’s disease (PD). The human MutY homolog (hMUTYH) which removes misincorporated adenine opposite 8-oxoG in DNA functions in post-replication, and is localized in the nuclei and mitochondria. We hypothesized that hMUTYH is involved in(More)
A 20-year-old Japanese man developed generalized, subcutaneous, painless nodules, fever, abnormal liver function, serosal effusions, hepatosplenomegaly, lymphadenopathy and anemia. Skin biopsies revealed lobular panniculitis with a morphologically benign histiocytic infiltration and prominent phagocytosis. Atypical T lymphocytes were also present in the(More)
Vesicular monoamine transporter 2 (VMAT2) is responsible for packing dopamine into vesicles, and reduces the effects of neurotoxins by sequestering them into vesicles. In this report, we tested the hypothesis that VMAT2 is associated with Lewy body (LB) formation by immunohistochemical staining of midbrain and cortical sections of autopsied brains of(More)
