"Misfolded and aggregated disease-specific proteins such as α-syn in Parkinson’s disease (PD) and Aβ and tau in Alzheimer’s disease (AD) are common features of many neurodegenerative diseases (NDs). Self-amplification, propagation, and transmission of these misfolded proteins are hypothesized as major contributing factors to disease onset and progression."

Working with mice, they showed that:
"α-syn immunotherapy using Syn303 reduced pathologic spread of α-syn aggregates in vivo, ameliorated motor dysfunction mediated by LB pathology, and rescued TH cell loss."
