Glucosylceramide accumulation — a hallmark of GBA1- and LRRK2-linked Parkinson’s disease — drives ectosome shedding from neurons. A study now shows that these plasma membrane-derived vesicles shuttle pathogenic α-synuclein across cells, revealing ectosomes as an underappreciated route of pathology propagation in Parkinson’s disease.
