Plasma growth-associated protein 43 correlates with synaptic loss in Alzheimer’s disease
Keywords synaptic loss blood biomarkers GAP-43 extracellular vesicles neuropathology Alzheimer’s disease Introduction Dementia is the leading cause of disability and death among older adults and currently affects over 55 million people worldwide.1 Approximately 60%–70% of dementia cases are attributed to Alzheimer’s disease (AD), marked by the deposition of extracellular amyloid-β (Aβ) plaques and intraneuronal tau tangles composed of phosphorylated tau (p-tau), and then dementia with Lewy...

Astrocyte and mitochondrial footprints in brain-derived extracellular vesicles predict tau pathology
Abstract Tauopathies are neurodegenerative disorders characterized by abnormal tau aggregation, with primary 3R (e.g., Picks disease, PiD) and 4R (e.g., progressive supranuclear palsy, PSP) variants posing a significant diagnostic challenge. Here, we examined brain-derived extracellular vesicles (BD-EVs) isolated from the prefrontal cortex of PiD (3R), PSP (4R), and non-demented controls (CTRL) to determine if these vesicles reflect disease-specific proteomic signatures.
