This study measures CSF glucosylsphingosine (GlcSph) levels in Parkinson’s disease patients and finds elevated GlcSph in GBA1 carriers and sporadic PD, indicating central GCase pathway impairment.

This study shows that LRRK2 kinase activity affects BMP and GSL levels in lysosomes, linking lysosomal dysfunction to Parkinson's disease through changes in GCase activity and BMP accumulation.

The paper develops and applies quantitative assays to measure LRRK2 and pRab10 levels in cellular models and human subjects to assess LRRK2 kinase activity and its association with Parkinson's disease.
