A new study identifies the Sigma-1 receptor as a potential new marker for extracellular vesicles (EVs) and shows it is enriched in CD63-labeled vesicles, suggesting it is released into the body through exosome secretion.
The significance of this work is that the presence of the Sigma-1 receptor on EVs could serve as a valuable biomarker for neurological disorders like Alzheimer’s disease, opening new avenues for diagnosis and further research.
