N6-methyladenosine (m6A) hypermethylation of SNCA mRNA in substantia nigra dopaminergic neurons stabilises the transcript, increases alpha-synuclein protein levels, and lowers the concentration threshold for protein aggregation into Lewy bodies. Pharmacological inhibition of METTL3 (the primary m6A writer) should reduce SNCA mRNA stability, lower alpha-synuclein protein levels, and decrease aggregation in PD model neurons.
Dopaminergic neurons with lysosomal stress (either from GBA1 mutations, VPS35 dysfunction, or age-related LAMP2A decline) release exosomes enriched in SNCA via a mechanism involving CD63 and syntenin-mediated exosome biogenesis at multivesicular bodies (MVBs). Critically, these exosomes carry a distinct cargo signature reflecting their lysosomal origin: they are enriched in mature cathepsins (particularly cathepsin D in its active form), LAMP1 fragments, and glucosylceramide. When these exosomes
