Regulation of Physiological Mitophagy

Targeting Mitochondria 2021 Dr. Thomas McWilliamsProf. Thomas G. McWilliams from University of Helsinki, Finland will join the Targeting Mitochondria 2021 congress and will present his research on Regulation of Physiological Mitophagy.

Summary of talk: Mitochondrial network dysfunction is neutralised by the selective autophagy of mitochondria (mitophagy). Mitophagy is widely thought to be a disease-relevant process and is routinely implicated in neurodegenerative pathology and mammalian aging. Yet, most of our knowledge and assumptions about mitophagy are derived from its induction as a PINK1-Parkin-dependent stress-responsein vitro. Converging data from multiple mitophagy reporter models suggests that this process is much more complex in tissues than previously appreciated. Mitophagy is a highly pervasive and heterogeneous processin vivo, that proceeds normally in the absence of the PINK1-Parkin signalling pathway. Using a multi-OMICs approach, we have defined the progression and regulation of PINK1-independent mitophagy, deciphering its integration with other homeostatic pathways to safeguard cellular and metabolic integrity.
