This hypothesis proposes that exosome-derived YKL-40, sTREM2, and neurogranin from peripheral blood samples can provide real-time monitoring of neuroinflammatory cascades during active neurodegeneration. Unlike static CSF measurements, exosomal cargo reflects dynamic cellular stress responses as microglia and neurons actively package distress signals into extracellular vesicles that cross the blood-brain barrier. The mechanistic framework centers on exosome biogenesis pathways where CHI3L1 expre
This hypothesis proposes that plasma-derived exosomes carrying YKL-40, sTREM2, and neurogranin provide a superior biomarker platform compared to CSF analysis by capturing real-time bidirectional brain-periphery communication. Exosomes released from activated microglia (sTREM2), reactive astrocytes (YKL-40), and compromised neurons (neurogranin) cross the blood-brain barrier and maintain molecular integrity in circulation for 6-48 hours, creating a dynamic temporal window for neurodegeneration as
