An autosomal recessive form of juvenile Parkinsonism (AR-JP) (MIM 600116) is a levodopa-responsive Parkinsonism whose pathological finding is a highly selective degeneration of dopaminergic neurons in the zona compacta of the substantia nigra. By linkage analysis of diallelic polymorphism of the Mn-superoxide dismutase gene (SOD2), we found a family with(More)
Interleukin (IL)-1 beta, IL-6, epidermal growth factor (EGF), and transforming growth factor-alpha (TGF-alpha) were measured for the first time in the brain (caudate nucleus, putamen and cerebral cortex) from control and parkinsonian patients by highly sensitive sandwich enzyme immunoassays. The concentrations of IL-1 beta, IL-6, EGF, and TGF-alpha in the(More)
Only a few human studies have reported the relationship between dietary factors and the risk of amyotrophic lateral sclerosis (ALS). We therefore analyzed the relationship between macronutrients (carbohydrate, protein and fat) and the risk of ALS using a case-control study in Japan. The study comprised 153 ALS patients diagnosed by the El Escorial World(More)
The proto-oncogene bcl-2 is involved in the regulation of cell death and may be able to block apoptosis in neurons through reduced generation of reactive oxygen species (ROS). The bcl-2 product was measured for the first time in brain (caudate nucleus, putamen and cerebral cortex), ventricular cerebrospinal fluid (VCSF), and lumber CSF (LCSF) from control(More)
Quetiapine has been suggested to be useful for the treatment of psychosis in patients with Parkinson's disease without prominent deterioration of motor functions. We present two patients with Parkinson's disease in whom administration of quetiapine for drug-induced psychosis caused characteristic stereotyped behaviors or punding. Since stereotyped behaviors(More)
We and other workers found markedly increased levels of proinflammatory cytokines and apoptosis-related proteins in parkinsonian brain. Although the pathogenesis of Parkinson's disease (PD) remains enigmatic, apoptosis might be involved in the degeneration of dopaminergic neurons in PD. To investigate the possible presence of other inflammatory cytokines(More)
Alzheimer's disease (AD)-specific or characteristic gene expression was explored by the identification of cDNA clones by means of differential screening for embryonic brain cDNA library with 32P-labeled cDNA probes prepared from mRNA of AD and normal human brains. To isolate neuronal genes in degenerating neurons, we used rat embryonic cDNA library at stage(More)
Fas is an apoptosis-signaling receptor molecule on the surface of a number of cell types. The soluble form of Fas (sFas) was measured for the first time in brain (caudate nucleus, putamen and cerebral cortex), ventricular cerebrospinal fluid (VCSF), and lumbar CSF (LCSF) from control and parkinsonian patients by a highly sensitive two-site sandwich(More)
The contents of interleukin (IL)-2 and basic fibroblast growth factor (bFGF) were measured in the brain (caudate nucleus, putamen, and cerebral cortex) from control and parkinsonian patients by highly sensitive enzyme-linked immunosorbent assay (ELISA). The concentrations of IL-2 in the brain were in the order of pg/mg protein, and the values were(More)
1. To elucidate the mechanisms regulating the release of striatal dopamine and its precursor, 3,4-dihydroxyphenylalanine (DOPA), we determined the effects of various Ca2+ channel antagonists, an N-type Ca2+ channel antagonist, omega-conotoxin GVIA, a P-type Ca2+ channel antagonist, omega-agatoxin IVA, and a Q-type Ca2+ channel antagonist, omega-conotoxin(More)
