Dr Helene Plun-Favreau a Senior lecturer and a cell biologist by training.
After a PhD in France (Angers University) in signal transduction, Helene did her postdoctoral work with Professor Julian Downward at CRUK. The discoveries and work she did in this area led her towards neurodegeneration and she was successful in being appointed to an MRC Career Development Fellowship to work in the Department of Molecular Neuroscience at UCL Institute of Neurology. Since her arrival in 2007 Helene has carried out some significant work on the molecular pathways associated with mitophagy and other mitochondrial dysfunctions in neurodegenerative disorders. The approaches they have undertaken require live cell microscopy and complex molecular and cellular biology, and provide a more complete picture of the pathways that play a role in the pathogenesis of neurodegeneration.
Mitochondria are the ‘energy powerhouses’ of cells. Their function is vital in long-lived neurons, where mitochondria must be maintained for an entire lifetime, and where a great deal of energy is required for them to function and survive.
The selective autophagy of damaged mitochondria (mitophagy) is critical for cell survival as it maintains optimal cellular energy production whilst avoiding the toxic accumulation of damaged mitochondria. Important information about the control of mitophagy has come from the study of the genes associated with autosomal recessive Parkinson’s disease. Of particular interest, PINK1 (mitochondrial kinase) and Parkin (E3-ubiquitin ligase) have been found to play crucial roles in mitophagy.
Against this background, our lab focuses on the following themes:
- Understanding further the mitophagy process
- Identifying the major molecular players in PINK1-induced mitophagy.
- Unravelling the upstream pathways that regulate the mitophagy process.
- Assessing mitophagy and other mitochondrial dysfunctions in iPSC-derived neurons from patients with Parkinson’s disease, and with other neurodegenerative diseases (E.g Alzheimer’s disease, Frontotemporal Dementia, Amyotrophic Lateral Sclerosis, mitochondrial DNA disease etc).
Our ultimate goal is to identify compounds that are able to modulate mitophagy and rescue mitochondrial pathophysiology and neuronal death.
