Research topics
I am mainly involved in metabolomics studies of human and animal brain. My main research projects are on Parkinson’s disease and focal epilepsy.
Parkinson’s disease (PD), metabolic biomarker discovery
- We conducted a large translational study of the different phases of PD, in collaboration with S. Boulet from Carnicella’s team (team “physiopathology of motivation”). This study included three different animal models and two de novo PD patient cohorts. We discovered a new blood biomarker exhibiting a high accuracy for de novo PD diagnosis and may possibly predict early PD development, before motor symptoms. This biomarker is being patented.
- We are now recruiting late and de novo PD patients at CHUGA (Grenoble Alpes hospital) through the BIOPARK project (E. Moro). We are also comparing the metabolic profile of parkinsonian patient to those of Alzheimer patients (S-PARK projet, M. Sauvee and A. Le Gouellec)
- On the mechanistic side of the project, we are now trying to dysregulate/upregulate some metabolic pathways which could be involved in the metabolic perturbations observed (V. Millasseau PhD project).
This project has been funded by foundation France Parkinson, by the Parkinson’s Disease Biomarkers Program (PDBP) Consortium, supported by the National Institute of Neurological Disorders and Stroke at the National Institutes of Health, by CHUGA, by IXXI (Complex system institute), by Fondation de France (2023), Fondation pour la recherché sur le cerveau (2024), ANR (project PYPARK, 2024, PI Sabrina Boulet).
Focal epilepsy, biomarker of the epileptogenic zone
The main objective of my research is to better delineate the epileptogenic zone (EZ) using NMR spectroscopy. First, an unbiased strategy based in ex vivo NMR-based metabolomics, followed by in vivo NMR spectroscopy, has suggested that GABA was a biomarker that accurately define the epileptogenic zone (EZ) in a mouse model of focal epilepsy (the kainate mouse model). We have then developped, in collaboration with Vasile Stupar, in vivo spectroscopic imaging of GABA in the same animal model (Alicia Plaindoux thesis, May 2024).
This project has been funded by Fondation Française pour la Rercherche sur l'Epilepsie (FFRE, METAB-O-EPI project) and by France Life Imaging (FLI, GABA-MAP project).
Other metabolomics project, mainly to find specific biomarkers of:
- Addiction (collaboration with S. Carnicella, GIN), mainly to alcohol, pre-clinical and clinical studies,
- Encephalitis (Collaboration with M. Le Marechal), clinical study
Scientific disciplines
I am specialized in Nuclear Magnetic Resonance (NMR) spectroscopy of small molecules, mainly in biomedical research field.
► Metabolomics to investigate metabolism and to improve diagnosis
- HRMAS NMR (High Resolution Magic Angle Spinning) for unprocessed sample analysis,
- High resolution NMR (biofluids e.g. serum, cerebrospinal fluid, fecal water...)
- Multivariate statistics : PCA, OPLS-DA..
► NMR study of interactions
- Intercalation of heterocycles with synthetic oligonucleotides
- Complexation of small molecules with different cyclodextrins, using multi-nuclei NMR and mass spectrometry (thesis)
- Drugs-membranes interactions (phospholipidic Liposomes) using 1H, 31P, 2H NMR.
► Quantification of NMR signals
- Semi-automatic quantification of HRMAS NMR brain tissus, collaboration to the development of jMRUI/QUEST algorithm (collaboration D. Graveron, Université Lyon1, La Doua, Villeurbanne).
