    Dysregulation of SNX1-retromer axis in pharmacogenetic models of Parkinson’s disease

    Since the identification of vacuolar protein sorting (VPS) 35, as a causative molecule for familial Parkinson’s disease (PD), retromer-mediated endosomal machinery has been a rising factor in the pathogenesis ...

    High prevalence of serum anti-NH2-terminal of α-enolase antibodies in patients with multiple system atrophy and corticobasal syndrome

    Hashimoto’s encephalopathy with serum anti-NH2-terminal of α-enolase (NAE) antibodies occasionally displays clinical symptoms such as cerebellar ataxia and parkinsonism. We studied the frequency of anti-NAE antib...

    α-Synuclein enhances histone H3 lysine-9 dimethylation and H3K9me2-dependent transcriptional responses

    α-Synuclein (αS) is a protein linked to Parkinson’s disease (PD) and related neurodegenerative disorders. It is mostly localized within synapses, but αS has also been suggested to play a role in the nucleus. W...

    ESCRT-0 dysfunction compromises autophagic degradation of protein aggregates and facilitates ER stress-mediated neurodegeneration via apoptotic and necroptotic pathways

    Endosomal sorting required for transport (ESCRT) complexes orchestrate endo-lysosomal sorting of ubiquitinated proteins, multivesicular body formation and autophagic degradation. Defects in the ESCRT pathway h...

    A case with anti-galactocerebroside antibody-positive Mycoplasma pneumoniae meningoencephalitis presenting secondary hypersomnia

    Galactocerebroside (Gal-C) is a major myelin component in the central nervous system. The anti-Gal-C antibody induced by mycoplasma infection may therefore be involved in the pathogenic mechanisms of mycoplasm...

    Suppression of dynamin GTPase decreases α-synuclein uptake by neuronal and oligodendroglial cells: a potent therapeutic target for synucleinopathy

    The intracellular deposition of misfolded proteins is a common neuropathological hallmark of most neurodegenerative disorders. Increasing evidence suggests that these pathogenic proteins may spread to neighbor...
