BACKGROUND Multiple sclerosis (MS) and neuromyelitis optica (NMO) occasionally have an extremely aggressive and debilitating disease course; however, its molecular basis is unknown. This study aimed to determine a relationship between connexin (Cx) pathology and disease aggressiveness in Asian patients with MS and NMO. METHODS/PRINCIPAL FINDINGS Samples(More)
There are two distinct subtypes of multiple sclerosis (MS) in Asians, optic-spinal (OSMS) and conventional (CMS). In OSMS, severe spinal cord lesions are characteristic while brain lesions are scant. We sought to clarify atypical brain lesions in OSMS by neuroimaging and pathological studies. For brain MRI, 124 consecutive Japanese patients with clinically(More)
BACKGROUND Differences in cytokine/chemokine profiles among patients with neuromyelitis optica (NMO), relapsing remitting multiple sclerosis (RRMS), and primary progressive MS (PPMS), and the relationships of these profiles with clinical and neuroimaging features are unclear. A greater understanding of these profiles may help in differential diagnosis. (More)

We studied the effects of G-CSF on microglial reactions in mutant SOD1 (mSOD1)-Tg (G93A) ALS model mice. Following hypoglossal axotomy, the numbers of neurons and microglia expressing GDNF were significantly lower in mSOD1-Tg mice than in non-transgenic (NTG) littermates. This decrease in the number of neurons after axotomy and a decrease in the number of(More)
Extensive aquaporin-4 (AQP4) loss without perivascular deposition of either activated complement or immunoglobulins is a characteristic of Baló's disease. Our aim in this study was to investigate the relationship between astrocytopathy and demyelination in Baló's disease, focusing on connexins (Cx), which form gap junctions among glial cells and myelin.(More)
Induced gamma activity has a key role in the temporal binding of distributed cortico-cortical processing. To elucidate the neural synchronization in the early-stage somatosensory processing, we studied the functional connectivity between the primary and secondary somatosensory cortices (SI and SII) in healthy subjects using magnetoencephalography (MEG) with(More)
BACKGROUND Abnormal intrathecal synthesis of IgG, reflected by cerebrospinal fluid (CSF) oligoclonal IgG bands (OBs) and increased IgG index, is much less frequently observed in Japanese multiple sclerosis (MS) cohorts compared with Western cohorts. We aimed to clarify whether genetic and common infectious backgrounds influence CSF IgG abnormality in(More)
Multiple sclerosis (MS) is a demyelinating disease of the central nervous system (CNS) while neuromyelitis optica (NMO) is an inflammatory disease of the CNS that selectively affects the optic nerves and spinal cord. An antibody for aquaporin-4 (AQP4), which is a water channel located in astrocyte foot process, is specifically positive for NMO and antibody(More)
This report describes, for the first time, an occurrence of wall-eyed bilateral internuclear ophthalmoplegia (WEBINO) in a 19-year-old female with neuromyelitis optica (NMO) spectrum disorder, who had anti-aquaporin-4 (AQP4) antibody. A high signal intensity lesion on T2-weighted MRI was detected in the midbrain tegmentum adjacent to the aqueduct, and(More)
UNLABELLED Protein interaction network-based pathway analysis (PINBPA) for genome-wide association studies (GWAS) has been developed as a Cytoscape app, to enable analysis of GWAS data in a network fashion. Users can easily import GWAS summary-level data, draw Manhattan plots, define blocks, prioritize genes with random walk with restart, detect enriched(More)
