Mitochondrial Dysfunction In Response To Neurotoxins And The Role Of Mitophagy, Samantha Giordano

Parkinson's disease (PD) is the second most common neurodegenerative disorder. Two major factors in both familial and sporadic PD are mitochondrial dysfunction and insufficient autophagy. My thesis research focuses on the interplay between these activities in PD. To investigate the common and differential effects of PD-inducing neurotoxins on mitochondrial bioenergetics and their relationships to cell survival, we used an in vitro culture system, differentiated dopaminergic SH-SY5Y neuroblastoma cells. We found that the neurotoxins rotenone, 1-methyl-4- phenylyridinium (MPP+) and 6-hydroxydopamine (6-OHDA), decreased mitochondrial respiration and induced cell death in these cells. The extent and characteristics of mitochondrial dysfunction in response to …
