Solve: Extracellular vesicle biomarkers for early AD detection

Extracellular vesicles (EVs), including exosomes and microvesicles, carry molecular cargo (proteins, miRNAs, lipids) from their cells of origin, including neurons, astrocytes, and microglia. Brain-derived EVs can cross the blood-brain barrier and be isolated from blood, CSF, or saliva, potentially serving as liquid biopsy biomarkers for Alzheimer disease. Key questions: Which EV-derived biomarkers (e.g., phospho-tau, amyloid-beta, synaptic proteins, inflammatory mediators) show the highest diagnostic accuracy for early/prodromal AD? How do EV subpopulations (neuronal vs glial origin) differ in their biomarker profiles? What are the technical challenges in EV isolation and characterization that limit clinical translation? Linked to 5 hypotheses and 5 targets.
