Professor Zhang Jing has innovated and developed a stable and rapid assay method for quantitative determination of nervous system-derived plasma extracellular vesicles (EVs) in plasma, through the innovative nano-flow cytometry detection technology, and innovated the discovery of a novel peripheral blood neurogenic EVs related marker NMDAR2A, to evaluate its diagnostic value for Alzheimer’s Disease (AD) (10). Here, GRIN2A is linked to Alzheimer disease.
