Cholesterol enhances lysosome-autophagosome fusion for better α-synuclein clearance in GBA L444P-mutated Parkinson disease.
It is reported, in a large cohort, that GBA-mutated PD patients exhibit lower serum cholesterol levels and cholesterol supplementation was found to enhance the autophagic flux and mitigate α-synuclein accumulation in vitro, whereas AAV-Srebp2 delivery increased α-synuclein clearance in GbaL444P/+ mice.
