Abstract
Biallelic mutations in the GBA1 gene, which encodes the lysosomal enzyme glucocerebrosidase (GCase), are a common high-risk factor for Parkinson’s disease (PD). Pharmacological chaperones (PCs) are being developed as an approach to treating of PD associated with mutations in the GBA1 gene. Using high performance liquid chromatography coupled with tandem mass spectrometry, we evaluated the enzymatic activity of GCase and the concentration of its substrate, hexosylsphingosine (HexSph), in brain tissue of the C57BL/6 mouse after administration of PCs GCase (ambroxol and N2). We showed an increase in GCase activity and a decrease in HexSph concentration in the brain tissue of mice treated with PCs GCase. For the first time, we have demonstrated the efficacy of PCs GCase N2 in brain tissue from C57BL/6 mice.
