This proposal seeks to 1) determine whether there are biomarkers associated with Parkinson's disease (PD) susceptibility and/or progression in exosome-proteomes derived from PD patients versus controls, and 2) to determine if LRRK2 expression and/or phosphorylation are significantly lowered in the exosomes of individuals treated with the potent LRRK2 kinase inhibitor sunitinib (a multi-kinase inhibitor compound), to establish an assay for on-target effects for future LRRK2 inhibitor clinical trials.
