Article Synopsis
- Recent studies suggest that there may be a connection between lysosomal storage disorders (LSDs) and symptoms of schizophrenia (SCZ), indicating that lysosomal dysfunction could play a role in SCZ development.
- The research involved analyzing lysosomal enzyme activities and alpha-synuclein levels in blood samples from patients with late-onset SCZ and comparing them to patients with Parkinson's disease and healthy controls.
- Significant differences were found, including decreased enzyme activity, higher concentrations of certain lysosphingolipids, and genetic variants linked to LSDs in early-onset SCZ patients, which may contribute to understanding the overlap between these conditions.
Article Synopsis
- Recent research indicates that specific variants of the LRRK2 gene may influence the function of a key lysosomal enzyme (GCase) and are linked to Parkinson's disease (PD) risk in a Russian population.
- The study involved sequencing the LRRK2 gene in 508 PD patients and 470 controls, revealing that variants p.M1646T and p.N2081D were significantly associated with increased PD risk.
- Additionally, carriers of the p.G2019S and p.N2081D variants showed elevated levels of a specific substrate (LysoGb3) and decreased activity of another enzyme (ASMase), suggesting a potential role of LRRK2 in sphingolipid metabolism alterations in PD.
Parkinson's disease (PD) is the second most common neurodegenerative disorder. Alpha-synuclein misfolding and aggregation resulting in neurototoxicity is a hallmark of PD. The prion properties of alpha-synuclein are still under discussion.

Impaired metabolism of alpha-synuclein (SNCA) and its aggregation are implicated in PD pathogenesis. SNCA has been identified as a highly significant genetic risk loci associated with the sporadic form of PD in across populations in GWAS and replicative studies.
