A lipid nanoparticle-based oligodendrocyte-specific mRNA therapy

Molecular Therapy: Nucleic Acids
Despite the wide range of applications of mRNA therapies, major difficulties exist in the efficient delivery of mRNA into oligodendrocytes, a type of glial cell in the brain. Commonly used viral vectors are not efficient in transforming oligodendrocytes.

A case of multiple system atrophy

Journal of International Medical Research, 2019
Multiple system atrophy (MSA) is the most rapidly progressive neurodegenerative disorder among the various types of synucleinopathies. The cause of MSA remains unknown, but it can involve the extrapyramidal system, the pyramidal system, the autonomic ...

Fibril-seeded animal models of synucleinopathies: Pathological mechanisms, disease modeling, and therapeutic implications

Neuroscience Research
Accumulating evidence suggests that prion-like spread of misfolded α-Synuclein (αSyn) underlies the pathological progression of Lewy body diseases (LBD).

Luminescent conjugated oligothiophenes distinguish between α-synuclein assemblies of Parkinson’s disease and multiple system atrophy

Acta Neuropathologica Communications, 2019
Synucleinopathies [Parkinson’s disease with or without dementia, dementia with Lewy bodies and multiple system atrophy] are neurodegenerative diseases that are defined by the presence of filamentous α-synuclein inclusions.

Multiple system atrophy [PDF]

Current Opinion in Neurology, 1998
Although the precise definition of multiple system atrophy has been difficult, a recent consensus in diagnostic criteria for multiple system atrophy has been achieved. This should lead to progress in defining the underlying pathophysiology of the neuroendocrine, autonomic and motor deficits characteristic of multiple system atrophy.

Impact of α-synuclein fibril structure on seeding activity in experimental models of Parkinson’s disease

npj Parkinson's Disease
The central pathogenesis of Parkinson’s disease involves the misfolding and aggregation of α-synuclein (α-syn). There is a widespread belief that α-syn can propagate in a prion-like manner, and α-syn preformed fibrils (PFFs) have been widely used to ...

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Cutaneous silent periods in multiple system atrophy

Biomedical Papers, 2015
Aim: The cutaneous silent period (CSP) is a spinal inhibitory reflex primarily mediated by A-delta fibers. Prolonged CSPs have been reported in patients with restless legs syndrome (RLS) and idiopathic Parkinson's disease (IPD).

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

FEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Plasma metabolite biomarkers for multiple system atrophy and progressive supranuclear palsy.

PLoS ONE, 2019
Radiological biomarkers have been reported for multiple system atrophy and progressive supranuclear palsy, but serum/plasma biomarkers for each disorder have not been established.
