Abstract:

 

Mitochondria perform a number of essential cellular functions, but their damage can lead to bioenergetic failure and the release of cytotoxins that are implicated in aging and in neurodegenerative disease. Fortunately, eukaryotes have evolved a number of cellular pathways to prevent and repair damaged mitochondria, and in extreme circumstances, to discard extensively damaged mitochondria altogether through a process termed mitophagy. Although the molecular mechanisms underlying the prevention and repair of damaged mitochondria have been long studied, the machinery tasked with the detection and degradation of damaged mitochondria emerged only recently through studies of the PINK1 and Parkin genes, mutations of which cause Parkinson’s disease. My talk will provide an overview of the current model by which damaged mitochondria are detected and degraded. I will also describe some of our recent proteomic and genetic data that bears on the mechanisms by which mitochondria are damaged and degraded in the nervous system, and the neurological consequences of accumulated mitochondrial damage.
