Supervisorbodies
Two supervisor bodies :
INSERM and Sorbonne University
Nutrition and obesities : systemic approaches
Our laboratory is conducting for many basic and translational research in the area of obesity and related metabolic disorders.It has several aims:
- to explore the disturbances of inter-organ dialogue and especially the role of adipose tissue
- identifying new ways to stratify the disease and new therapies to improve cardiometabolic health.
Topic 1 : Progression of obesity and related complications: role of gut microbiota?
Team
Leaders: K Clément (PU-PH) and J Aron-Wisnewsky (MCU-PH)
Team Contributors: R Alili, C Poitou, S André, I Dugail, M Guerre-Millo, N Sokolovska, H Soula
Main collaborators: JD Zucker, International consortia Metacardis, ePos, Litmus (IMI2), INRA
Main Objectives
- Define gut microbiota signature in CMD and evaluate the impact of environment (diet and drugs)
- Demonstrate causality of CMD microbial signature in the development of CMD or its resolution:
- in human interventions: Metacardis follow-up (development), diet or bariatric surgery (reversal)
- in mice: gut microbiota transfer experiments (induce CMD or its reversal)
Topic 2 : Intestine as a key player in metabolic disorders
Team
Leaders : A Ribeiro (CR INSERM), S André (MCU SU), P Serradas (PU SU)
Team contributors : C Amouyal, L Genser, A Leturque, C Osinski, C Poitou, H Soula, F Andreelli
Main collaborators: P. Collombat (France), U Meinzer (France), C. Alvarez (Espagne), C. Magnan (France), G. Gorochov (France), R. Regazzi (Suisse), G. Mithieux (France).
Main objectives
The intestine is a target for changes in external (food, microbiota) and internal (immune system) environment. Gut adaptation has in turn consequences on gut immunity, epithelial cells homeostasis and key organs for energy balance.
Topic 3 : Adipose tissue Remodeling
Team
Leaders : I Dugail (DR INSERM) and G Marcelin (Post-doc)
Team Contributors: C Rouault, C Gamblin,, M Guerre-Millo, J Aron-Wisnewsky, F Marquet, P Bellassen, K Clément
Main collaborators: Laurent Yvan-Charvet (F), Emmanuel Gautier (F), Genevieve Desrumeaux (F), Adaliene Fereira (Brasil), F Charlotte, G Le Naour, D Sasson (Inserm F)
Main Objectives
- Understand white adipose tissue (WAT) fibrosis : role of progenitors
- Characterize WAT senescence :
- Evaluate inappropriate turnover of subcellular components (Lysosomal degradation)
- Examine PG as gut-derived signaling modulators in AT remodeling
Topic 4: Systems’ biology and data integration
Team
Leaders: N Sokolovska (MCU SU) and Hedi Soula (PU SU)
Team contributors: Flavien Jacques (IE), All team members (link with experimental and clinical approaches Main collaborators: JD Zucker (DR IRD / SU), Edi Prifti (IR ICAN), Eugeni Belda (IR, ICAN), Yann Chevaleyre (PU P12), Blaise Hanczar (PU Evry), P.-H. Wuillemin (LIP6, SU), consortia internationaux (ePos, Metacardis, Litmus)
Main Objectives
We will develop innovative tools for data analysis, physiological status prediction, and visualisation in metabolic diseases. Convergence of techniques include statistical inferences, machine learning, and mechanistic approach using dynamical systems. This WP is strongly integrated with the other WPs which produce large-scale data.
Topic 5 : Translating our fundamental research for the benefit of patients
Team
Leaders: C Poitou (PU-PH) and J Aron-Wisnewsky (MCU-PH)
Team Contributors: K Clément, P Tounian, B Dubern, F Marchelli, F Marchelli, L Genser
Main collaborators: M Tauber (F), S Farooqi (UK), A Rudich (Israel), P Kuhnen (G)
Main Objectives
Two main axes
- Develop innovative diagnosis and predictive factors/tools
- for patient stratification
- to predict poor responders’ outcomes after interventions (diet or bariatric surgery) or after treatment in genetic obesities
- discover new mutation/genes/pathways in rare obesities
- Develop novel approaches for therapy with personalized medicine
- improve the outcomes of poor responder’s response by adding other specific interventions (physical activity, specific diet, pre or prebiotic that modulates gut microbiota)
- implement new treatments in rare obesities
