SUMMARY

# Alpha-Synuclein Spreading Mechanism — Prion-Like Propagation and Neurodegeneration ## Background and Rationale Alpha-synuclein spreading through prion-like propagation mechanisms represents one of the most significant paradigm shifts in our understanding of Parkinson's disease pathogenesis and offers unprecedented opportunities for therapeutic intervention. This neuronal protein, encoded by the SNCA gene located on chromosome 4q22.1, normally functions as a synaptic protein involved in vesicle

METHODOLOGY NOTES

**Phase 1: Human Brain Tissue Collection and Processing (Weeks 1-4)** • Obtain postmortem brain tissue from 30 confirmed PD patients and 15 age-matched controls through established brain banks • Collect samples from substantia nigra, striatum, cortex, and brainstem regions within 12 hours of death • Process tissues for histological analysis, protein extraction, and cryo-preservation at -80°C • Perform immunohistochemical staining using anti-α-synuclein antibodies (Syn211, LB509) to confirm pathological aggregates **Phase 2: Alpha-Synuclein Aggregate Isolation and Characterization (Weeks 5-8)** • Extract pathological α-synuclein aggregates from PD brain tissue using sarkosyl-insoluble fractionation protocol • Characterize aggregate morphology using transmission electron microscopy and atomic force microscopy • Analyze aggregate composition using mass spectrometry and Western blot with conformation-specific antibodies • Quantify seeding activity using real-time quaking-induced conversio
