Spatial Single-Cell Proteomics Reveals Molecular Trajectories Of Tangle-Bearing Neurons In Alzheimer's Disease
By integrating laser microdissection with mass spectrometry-based proteomics on individual neurons in post-mortem Alzheimer's disease brains, this study reveals that tangle-bearing neurons undergo a continuous, adaptive molecular trajectory characterized by early proteostasis remodeling and synaptic disruption rather than discrete pathological classes or acute cell death.
