NCT04436848

Brief Summary

Given the emerging evidence on LRRK2-related biomarkers, this project will focus on identifying leucocyte and urine biomarkers that are altered by the LRRK2 G2385R variant, and investigating the effects of LRRK2 kinase inhibitor (MLi-2) on these biomarkers, using immunoblotting and mass spectrometry.
