METABOLINK

Cédric Dray / Armelle Yart

Metabolic interplays and age-related loss of function

Team Metabolink

During lifespan, environmental fluctuations consistently forced organism and cells to develop metabolic flexibility in order to maintain their energy homeostasis.

In this context, many aspects of cellular/tissue metabolism changes are driven by redox metabolism as well as inter-cellular and inter-organs metabolic interactions that are fundamental to maintain tissue and whole body energetic homeostasis. Altogether, these parameters are in constant adaptation and represent the metabolic resilience of cell (cell capacity to face metabolic alterations).

Cibler le dialogue métabolique systémique et local afin d’améliorer la flexibilité métabolique
Targeting systemic and local metabolic dialogue to improve metabolic flexibility

We hypothesized that metabolic resilience directs the ability of the aging organism to maintain the main metabolic functions (storage, utilization and release of energy) necessary to perform towards healthy-aging or dependence when disrupted.

Our aim is to investigate the role and the regulation of local/systemic metabolic dialogue within a tissue (mesenchyma/parenchyma) and between metabolic tissues (adipose tissues/muscle/liver) by focusing on intracellular changes in metabolic pathways and redox state triggering major modifications of secretion and cell production. This will allow identifying new mechanisms that contribute, when defective, to the onset
