Dual targeting approach using substrate reduction therapy (eliglustat) combined with TFEB activators to reduce GlcCer accumulation while enhancing lysosomal clearance
Debate provenance: derived from debate `sess_sda-2026-04-01-002` on question: How to break the GBA-alpha-synuclein bidirectional loop for Parkinson's Disease therapy?. Consensus signal: domain_expert, skeptic, synthesizer, theorist discussed the mechanism terms Enhancement, Glucosylceramide, Inhibition, Lysosomal, Selective, Synth
We propose that GBA deficiency-driven accumulation of glucosylceramide (GlcCer) in lysosomal membranes creates ordered lipid raft-like microdomains that serve as high-affinity nucleation sites for alpha-synuclein (αSyn) binding and fibrillization. The resultant αSyn oligomers directly interact with LIMP-2 (SCARB2), the mannose-6-phosphate receptor responsible for trafficking pro-GBA from ER to lysosome, impairing its function and causing further GBA mislocalization. This creates a self-reinforci
