Food Circus: Mechanisms of neuronal circuits sensitivity to nutritional status

Leader: Guillaume Ferreira, DR2 INRAE

Deputy leader: Pierre Trifilieff, DR2 INRAE

Gui et Pierre_Arnaud3

Team presentation

The general objective of FoodCircus is to establish causal mechanistic links between nutrients biostatus and behavioral phenotypes/dimensions with symptomatic relevance for neurological and psychiatric disorders, through the identification of the underlying cellular/molecular mechanisms within discrete neuronal circuits. 

Investigators of FoodCircus focus on neuronal circuits within two main vulnerable brain systems: the hippocampal and fronto-striatal circuits which control cognitive processes such as mnemonic and executive functions. Nutrient status mainly concern saturated/unsaturated fats and the fat-soluble vitamin A, which have been consistently linked with the etiology of several brain disorders. This multidisciplinary research program is based on the following specific aims: 

i) To elucidate the neuronal mechanisms by which obesogenic diet impairs hippocampal-dependent memory. 

ii) To identify the mechanisms by which polyunsaturated fatty acids and vitamin A biostatus impact neuronal circuits modulated by dopamine transmission and related to executive functions.

Beyond the prerequisite for a better understanding of the processes by which nutrients biostatus can alter specific brain functions, the perspectives of such a project are to identify targetable factors for the alleviation or prevention of specific symptomatic dimensions of brain disorders.
