LRRK2 G2019S Kinase Inhibition for Parkinson's Disease

Hypothesis

LRRK2 G2019S Kinase Inhibition for Parkinson's Disease

LRRK2 G2019S mutation hyperactivates kinase activity, causing excessive phosphorylation of Rab GTPases (Rab8A, Rab10, Rab12), impairing endosomal trafficking and lysosomal degradation of α-synuclein.

🧪 Overview

LRRK2 G2019S mutation hyperactivates kinase activity, causing excessive phosphorylation of Rab GTPases (Rab8A, Rab10, Rab12), impairing endosomal trafficking and lysosomal degradation of α-synuclein. Selective LRRK2 inhibitors restore lysosomal function and reduce pathological α-synuclein accumulation.
