BACKGROUND Many pathogens use a type III secretion system to translocate virulence proteins (called effectors) in order to adapt to the host environment. To date, many prediction tools for effector identification have been developed. However, these tools are insufficiently accurate for producing a list of putative effectors that can be applied directly for(More)
Signal transducer and activator of transcription-3 (STAT3) is a member of the proinflammatory transcription factor STAT family. Several studies have documented implications for neuroinflammation in amyotrophic lateral sclerosis (ALS). We recently demonstrated activation of STAT3 in spinal cords obtained at autopsy from sporadic ALS patients. To determine(More)
Several studies have documented the involvement of oxidative stress represented by lipid peroxidation in the pathogenesis of Alzheimer's disease (AD). To test whether the highly reactive carbonyl crotonaldehyde (CRA), generated during lipid peroxidation, is involved in AD, we performed an immunohistochemical analysis in AD and age-matched control hippocampi(More)
Bone-eating worms of the genus Osedax exclusively inhabit sunken vertebrate bones on the seafloor. The unique lifestyle and morphology of Osedax spp. have received much scientific attention, but the whole process of their development has not been observed. We herein report the postembryonic development and settlement of Osedax japonicus Fujikura et al.(More)
Growing evidence documents oxidative stress involvement in ALS. We previously demonstrated accumulation of a protein-bound form of the highly toxic lipid peroxidation product crotonaldehyde (CRA) in the spinal cord of sporadic ALS patients. In the present study, to the determine the role for CRA in the disease processes of superoxide dismutase-1 (SOD1)(More)
Recent studies have suggested implications for α-synuclein cytotoxicity in the pathomechanism of multiple system atrophy (MSA). Given in vitro evidence that α-synuclein generates oxidative stress, it is proposed that lipid peroxidation may be accelerated in MSA. To address this issue, we performed an immunohistochemical analysis of protein-bound(More)
Hypoglycosylation of alpha-dystroglycan (alpha-DG) has been identified in several human diseases associated with muscular dystrophy and brain malformations, including Fukuyama-type congenital muscular dystrophy (FCMD) caused by mutations in the fukutin gene. Although disruption of the intra-extra membrane linkage in the sarcolemma via the dystroglycan (DG)(More)
BACKGROUND It is well known that expression of certain bacterial genes responds rapidly to such stimuli as exposure to toxic chemicals and physical agents. It is generally believed that the proteins encoded in these genes are important for successful survival of the organism under the hostile conditions. Analogously, the proteins induced in bacterial cells(More)
BACKGROUND Emerging evidence suggests that innate immunity and increased oxidative stress contribute to pathomechanisms in amyotrophic lateral sclerosis (ALS). The aim of the present study was to verify the involvement of monocyte chemoattractant protein-1 (MCP-1) and its specific CC chemokine receptor 2 (CCR2) in the disease progression of ALS. We here(More)
To test the hypothesis that the disruption of fukutin protein produces the brain pathology through hypoglycosylation of alpha-dystroglycan (alpha-DG), we immunostained Fukuyama congenital muscular dystrophy (FCMD) brains with an antibody that recognizes the polysaccharide epitope of alpha-DG. Immunoreactivity of the glia-limitans along the cortical surface,(More)
