Dose-Dependent Alterations of Lysosomal Activity and Alpha-Synuclein in Peripheral Blood Monocyte-Derived Macrophages and SH-SY5Y Neuroblastoma Cell Line by upon Inhibition of MTOR Protein Kinase - Assessment of the Prospects of Parkinson's Disease Therapy.

To date, the molecular mechanisms of the common neurodegenerative disorder Parkinson's disease (PD) are unknown and, as a result, there is no neuroprotective therapy that may stop or slow down the process of neuronal cell death. The aim of the current study was to evaluate the prospects of using the mTOR molecule as a potential target for PD therapy due to the dose-dependent effect of mTOR kinase activity inhibition on cellular parameters associated with, PD pathogenesis. The study used peripheral blood monocyte-derived macrophages and SH-SY5Y neuroblastoma cell line.

The Effect of p.G2019S Mutation in the Gene on the Activity of Lysosomal Hydrolases and the Clinical Features of Parkinson's Disease Associated with p.N370S Mutation in the Gene.

Background: Mutations in the glucocerebrosidase () and leucine-rich repeat kinase 2 () genes, encoding lysosomal enzyme glucocerebrosidase (GCase) and leucine-rich repeat kinase 2 (LRRK2), respectively, are the most common related to Parkinson's disease (PD). Recent data suggest a possible functional interaction between GCase and LRRK2 and their involvement in sphingolipid metabolism. The aim of the present study was to describe the clinical course and evaluate the lysosomal enzyme activities and sphingolipid concentrations in blood of patients with PD associated with dual mutations p.

Whole Transcriptome Analysis of Substantia Nigra in Mice with MPTP-Induced Parkinsonism Bearing Defective Glucocerebrosidase Activity.

Mutations in the gene represent the major genetic risk factor for Parkinson's disease (PD). The lysosomal enzyme beta-glucocerebrosidase (GCase) encoded by the gene participates in both the endolysosomal pathway and the immune response. Disruption of these mechanisms is involved in PD pathogenesis.
