In GBA-associated PD, reduced glucocerebrosidase activity leads to glucosylceramide accumulation in neurons and glia, which directly promotes α-synuclein fibrillization by stabilizing toxic oligomers and disrupting membrane curvature. These α-synuclein aggregates subsequently traffic to the lysosome where they inhibit wild-type GBA activity and impair ER-Golgi trafficking of new GBA enzyme, creating a feedforward loop. I hypothesize that pharmacological restoration of GBA activity using alloster
