Role of polysialic acid (PSA) in the control of food intake and body weight

2013

Hypothalamus plays a major role in the regulation of energy homeostasis by the presence of neural circuits controlling food intake. These circuits are plastic and can be rewired during adulthood. We hypothesized that synaptic plasticity can occur during physiological conditions. We have shown that synaptic contact on hypothalamic anorexigen POMC neurons are rewired in mouse upon high fat diet (HFD). This synaptic process is mandatory to adjust energy intake and requires the glycan PSA (polysialic acid). PSA promotes synaptic plasticity in the brain by the weakening of cell-to-cell interaction by addition on NCAM (neural cell adhesion molecule). We hypothesized that a defect in brain synapti…

Parasite-induced alteration of plastic response to predation threat: increased refuge use but lower food intake in Gammarus pulex infected with the a…

6 pages; International audience; Larvae of many trophically-transmitted parasites alter the behaviour of their intermediate host in ways that increase their probability of transmission to the next host in their life cycle. Before reaching a stage that is infective to the next host, parasite larvae may develop through several larval stages in the intermediate host that are not infective to the definitive host. Early predation at these stages results in parasite death, and it has recently been shown that non-infective larvae of some helminths decrease such risk by enhancing the anti-predator defences of the host, including decreased activity and increased sheltering. However, these behavioura…

Etude du contrôle hédonique de la prise alimentaire par l'analyse des potentiels évoqués gustatifs

2016

Hedonic control of food intake has been studied using neurophysiological investigations in animals and functional imaging in humans. Gustatory evoked potentials (GEPs), a higher time resolution technique than functional imaging, have never been used for this purpose. The first aim of this thesis was to establish a reliable recording of GEPs in humans, in response to a sapid stimulus. The second aim was to determine the GEPs modifications according to the hedonic value of food intake. GEPs recording was performed in response to an intermittent stimulation of a sapid solution in more than 100 young healthy subjects. The comparisons between cerebral recordings in response to water or paraffin …

Evidence for interactions between aroma compounds and the CB1 receptor: a way to regulate food intake?

2012

National audience; Obesity is a major cause of morbidity and mortality worldwide, characterised by a chronic imbalance of energy homeostasis. The regulation of dietary intake appears to be an effective way to regulate this imbalance. Furthermore, it is now well established that the endocannabinoid system influences appetite via the cannabinoid receptor type 1 (CB1): CB1 agonists can promote food intake while CB1 antagonists tend to decrease appetite (1). Interestingly, recent studies showed that CB1-like receptors are expressed in the olfactory epithelium of Xenopus laevis tadpoles (2). Elsewhere, it has been demonstrated that aroma perception is implicated in the process of satiety (3). Co…

A sensory perspective on the development of food likes in children: implication for food intake

2014

All aspects of eating habits (i.e. ‘how', ‘what', ‘when', and ‘how much' to eat) are learned, essentially during the first years of life (1). Moreover eating habits established in the early years will contribute to the development of subsequent eating habits (2-4). At this stage, nutrition is still critical for child development, so parental choices bear a key importance for future health. It therefore appears essential to understand the most important periods for the acquisition of healthy eating habits, as well as the most important factors driving eating habits. Since eating behaviour is complex and multi-determined, these factors may be multiple. Because in our sophisticated, superabund…
