Recently, the team of Professor Zhang Jing from Zhejiang University School of Medicine published an article in Brain Journal reporting on the relationship between
oligodendrocyte exosome secretion and pathological α-syn aggregation and SNARE complex dysfunction in multisystem atrophy (MSA).
Multisystem atrophy (MSA) is a rare neurodegenerative disease characterized by autonomic dysfunction, parkinsonism, cerebellar impairment, and cone bundle signs
.
Although there is still a lack of complete understanding of the underlying pathogenesis of MSA, a-syn aggregation appears to be at least one contributing factor
.
These findings suggest that extracellular vesicles and their a-syn cargo may undergo similar alterations
in MSA.
The study developed a novel immunocapture technique to isolate CNPase-positive, oligodendrocyte-derived enriched microvesicles (OEMVs) in the blood, followed by fluorescent nanoparticle-tracking analysis and assessment of α-syn levels
contained in OEMVs.
A-Syn-syntaxin4 interactions regulate SNARE complex function and exosome secretion
