SUMMARY

# Synaptic Vesicle Trafficking Dysfunction Validation in Parkinson's Disease ## Background and Rationale # Synaptic Vesicle Trafficking Dysfunction Validation in Parkinson's Disease Synaptic vesicle trafficking represents a fundamental cellular process essential for neurotransmitter release and neuronal communication. Emerging evidence suggests that dysfunction in this pathway may contribute significantly to the pathophysiology of Parkinson's Disease (PD), particularly through mechanisms involv

METHODOLOGY NOTES

**Phase 1: Patient Recruitment and Sample Collection (Months 1-6)** • Recruit 150 Parkinson's disease patients (Hoehn & Yahr stages 1-3) and 75 age-matched healthy controls • Obtain informed consent and collect detailed clinical assessments (UPDRS-III, MoCA, disease duration) • Collect peripheral blood samples (50mL) for genetic analysis and iPSC generation • Perform comprehensive genetic screening for SVT variants and known PD risk alleles (SNCA, LRRK2, GBA, PARK genes) • Generate induced pluripotent stem cells (iPSCs) from skin fibroblasts using Sendai virus reprogramming **Phase 2: Neuronal Differentiation and Culture (Months 4-10)** • Differentiate iPSCs into midbrain dopaminergic neurons using dual SMAD inhibition protocol • Validate neuronal identity using TH, FOXA2, and LMX1A immunostaining (>80% positive cells required) • Maintain neuronal cultures for 60-90 days to achieve synaptic maturation • Prepare co-cultures with astrocytes at 4:1 neuron:astrocyte ratio for enhanced syn
