IF ApoE and clusterin are immunodepleted from Parkinson's disease CSF using anti-ApoE (e.g., HJ6.3) and anti-clusterin (e.g., G7) antibodies, THEN the residual fibril seeding activity measured by real-time quaking-induced conversion (RT-QuIC) will decrease by >50% compared to non-depleted CSF within
Predicted outcome: ≥50% reduction in ThT fluorescence maximum rate (seconds⁻¹) and延长lag phase in RT-QuIC assay using αSyn substrates (recombinant human αSyn 1-140)
Falsification: No significant change in seeding kinetics (<20% difference) after immunodepletion compared to sham-depleted controls, indicating lipoproteins are not essential for fibril stability

IF recombinant human ApoE3 (10 μg/mL) and clusterin (50 μg/mL) are added to pre-formed αSyn fibril polymorphs derived from DLB patient brain tissue, THEN the structural integrity of distinct strain conformations (assessed by limited proteolysis-mass spectrometry fingerprint) will be preserved after

Falsification: Fibril polymorph signature diverges equally (≥40% change) in both ApoE/clusterin-coated and uncoated conditions after protease exposure, demonstrating no stabilizing effect of lipoproteins
