Degenerative and vascular cognitive discorders


This team, made up of clinical and pre-clinical researchers, is multidisciplinary. It is located at the interface between neurology, pharmacology and imaging. The research project is focused on the translational, transnosographic and multimodal study of cognitive disorders associated with degenerative processes or neurovascular lesions, starting from the observation that the mechanisms are entangled.



Neurodegenerative diseases are multifactorial but are all characterized by the regulated death of neurons which, depending on their location, have variable clinical expressions. For a long time, the dogma of a single regulated death by apoptosis limited research. Among other forms, ferroptosis has been described recently and is characterized by iron dependence and an accumulation of peroxidized lipids at the membrane level leading to its rupture. We have demonstrated in vitro and in vivo that human dopaminergic neurons are particularly sensitive to ferroptosis and that specific inhibitors such as Ferrostatin-1, Liproxstatin-1 and iron chelators are potent neuroprotective agents.

We are now working on alpha-synuclein, lipid metabolism and mitochondrial energy metabolism linkages while developing specific biomarkers of target engagement, drug discovery and large therapeutic trials.

New biomarkers and new treatments: Iron overload and massive lipid peroxidation offer new biomarkers by imaging and biology that allow to better define populations with a ferroptotic process and to monitor therapeutic efficacy to facilitate the development of new chelators (Abfero, Alterity) and antiferroptotics (PTC Therapeutics) or deferiprone in ALS (FAIRALS study).

Drug discovery: Enrichment with polyunsaturated fatty acids sensitizes ferroptose. Inhibition of enzymes involved in lipid metabolism (ACSL4 and LOX15) prevents lipid peroxidation and cell death. The variation in levels of ∝-synuclein modulates sensitivity to ferroptosis but not to other forms of cell death offering new therapeutic targets (LOX15 inhibitors, PTC Therapeutics) and new molecules (Lille and Cambridge co-development).
