Mechanisms of gustatory perception of dietary lipids : cross-talk with bitter taste and endocannabinoid receptors
2018
Obesity is one of the major public health problems at the beginning of the 21st century. Its prevalence is increasing steadily, especially among children. This observation is not insignificant because obesity is generally associated with various serious pathologies (type 2 diabetes, hypertension and cancer, etc.). Thus, investigations into the mechanisms involved in the taste perception of dietary lipids could shed light on their roles in the incidence of obesity.Several studies have demonstrated the role of endocannabinoids and bitter foods in obesity. Thus, we studied the cross-talk of cannabinoid receptors and bitter taste with lipid taste. This thesis has two components: cannabinoid rec…
Impact du système endocannabinoïdien sur la physiologie de l'obésité : effets de l'antagonisme des récepteurs CB1 sur le métabolisme glucido-lipidiqu…

The endocannabinoïd system (ECS) is involved in many biological functions such as regulation of energy metabolism. Recently, several studies have shown an association between obesity and ECS overactivity. In addition, specific CB1R antagonists such as Rimonabant (SR141716) improved metabolic parameters in obese patients essentially through inactivation of central CB1R. However, peripheral CB1R inactivation could also contribute to the improvement of these parameters and it is this notion that we have studied. To this purpose, we tested the effects of SR141716 on obese mice in order to establish relationships between the ECS activity and lipid metabolism by looking more specifically to its r…
Prenatal Exposure to Δ9-Tetrahydrocannabinol Affects Hippocampus-Related Cognitive Functions in the Adolescent Rat Offspring: Focus on Specific Marke…
2023
Previous evidence suggests that prenatal exposure to THC (pTHC) derails the neurodevelopmental trajectories towards a vulnerable phenotype for impaired emotional regulation and limbic memory. Here we aimed to investigate pTHC effect on hippocampus-related cognitive functions and markers of neuroplasticity in adolescent male offspring. Wistar rats were exposed to THC (2 mg/kg) from gestational day 5 to 20 and tested for spatial memory, object recognition memory and reversal learning in the reinforce-motivated Can test and in the aversion-driven Barnes maze test; locomotor activity and exploration, anxiety-like behaviour, and response to natural reward were assessed in the open field, elevate…
