SUMMARY

# Astrocyte Ferritin Iron Metabolism Dysfunction in Parkinson's Disease ## Background and Rationale This clinical study investigates the role of astrocyte ferritin iron metabolism dysfunction in Parkinson's disease (PD) pathogenesis. Iron accumulation in the substantia nigra is a hallmark of PD, contributing to oxidative stress and neurodegeneration. Astrocytes, the most abundant glial cells in the brain, regulate iron homeostasis through ferritin storage and iron transport mechanisms. Recent ev

METHODOLOGY NOTES

Phase 1: Recruit 80 PD patients (Hoehn-Yahr stages 1-3) and 40 age-matched healthy controls from movement disorder clinics. Obtain informed consent and perform comprehensive clinical assessments including UPDRS-III, MoCA, and Hoehn-Yahr staging. Phase 2: Conduct high-resolution 3T MRI with quantitative susceptibility mapping sequences to measure iron deposition in substantia nigra, putamen, and cortical regions. Acquire T1-weighted and diffusion tensor imaging for structural analysis. Phase 3: Perform lumbar puncture to collect 15mL CSF under standardized conditions. Analyze CSF for ferritin heavy/light chains, transferrin, lactoferrin, hepcidin, and inflammatory markers using ELISA and multiplex assays. Measure total iron, copper, and zinc concentrations using inductively coupled plasma mass spectrometry. Phase 4: Collect blood samples for serum iron studies, ferritin, transferrin saturation, and genetic analysis of iron metabolism genes (HFE, TFRC, FTH1, FTL). Phase 5: For consenting
