Abstract (Summary)

This dissertation details my Ph.D. work in Dr. Sreeganga Chandra's laboratory at Yale University studying regulators of α-synuclein aggregation in Parkinson's disease. I first discuss my work probing the molecular mechanism behind GBA-linked Parkinson's disease. Using in vitro methods, mouse lines, and iPSC-derived human neurons, I show that glycosphingolipids accumulating as a result of GBA mutations promote a-synuclein aggregation, leading to an increased risk for Parkinson's disease in affected populations. I then describe my work studying the effects of a chaperone disaggregase complex on mitigating a-synuclein aggregation. Through the characterization of an established Parkinson's disease mouse line crossed with a line overexpressing the disaggregase machinery, I show that the chaperone disaggregase complex is capable of mitigating asynuclein pathology in vivo.

Together, my thesis work describes two cellular players involved in both promoting and preventing pathological α-synuclein aggregation in Parkinson's disease, contributing to our knowledge of the disease and informing on potential therapeutic targets in treating Parkinson's disease.
