Parkinson's disease (PD) is the second most common neurodegenerative disease worldwide
Figure 1: Paper cover image
Decreased GCase activity has been described in the brain tissue of PD patients with and without GBA1 mutations, and in healthy aging subjects, but a recent study showed no association between total GCase activity and PD risk sex
Hereby, Danielle te Vruchte et al.
They analyzed plasma GSLs and glucoglyceramide (GlcCer) using two normal-phase high-performance liquid chromatography methods; extracting clinical demographic data
Figure 2: The results of the paper
They analyzed 80 PD subjects and 25 HCs
PD patients had higher levels of GlcCer, GD1b, Gb4, GalNAcGA1, and series b than HCs; PD patients had lower levels of total GSLs, GT1b, GM1a, GM3, GM2, and series a than HCs
Results were similar after excluding some GBA1 mutation carriers
The significance of this study lies in the discovery that multiple GSL abnormalities in plasma were detected in patients with and without changes in GlcCer, suggesting a broader shift in lipid homeostasis
