SUMMARY:Exhibition "Disgusting Food Museum"
DESCRIPTION:Cap Sciences \nWith the partnership of Bordeaux Neurocampus / University of Bordeaux \n\nYuck ! What seems disgusting to some is not necessarily so to others ! Who will have the guts to smell that stinky cheese or taste a fermented shark or a cricket ? Disgusting food Museum presents 85 of the world’s most disgusting foods. The opportunity for adventurous visitors to wander from table to table between turtle soup\, insects or hundred–year–old eggs… Everyone puts their disgust to the test\, a beautiful way to change our preconceived ideas\, to question what seems edible or not and to open up to other food practices. This exhibition illustrates the cultural dimension of food and our propensity to change it. Curious” foods from exotic cultures have always fascinated us. In addition to the pleasure of curiosity and discovery\, everyone will be able to put into perspective one of the six fundamental human emotions\, which is disgust. The visit is completed by a tasting at the bar where visitors can test several products from a selection. An exhibition of the Disgusting Food Museum (Malmö Sweden) and with the kind collaboration of the Alimentarium (Vevey Switzerland). Average length of visit: 1 hour All public / from 6 years old On social media\, comment and share about the exhibition with: @capsciences #DisgustingFoodMuseum \n  \nMore details\nhttps://www.cap-sciences.net \n

SUMMARY:Thesis defense - Léa Tochon
DESCRIPTION: Venue: Amphi E – ENSEIRB-MATMECA\, Talence (Bâtiment Bordeaux INP\, Avenue des Facultés\, 33400 Talence; arrêt du tram B “Arts & Métiers”). \nDefense in french \n\n\nLéa Tochon \nINCIA \nThesis supervisor :\nVincent David \n\nTitle\nMechanisms of vulnerability to alcohol use disorders induced by a single nucleotide polymorphism of the gene encoding the alpha5 nicotinic acetylcholine receptor subunit \nAbstract\nHuman genetic studies have implicated gene variants in the CHRNΑ5 gene\, encoding for the α5 nicotinic acetylcholine receptor subunit (α5-nAChR)\, as high risk factors for developing alcohol use disorders (AUDs). The single nucleotidic polymorphism (SNP) D398N is highly represented in Western population (in ~35% of individuals). Yet\, mechanisms through which they may influence this risk remain unknown. In this context\, the aim of my PhD was to understand how the α5-SNP modify behavioral processes and neural circuits involved in the vulnerability to AUDs. To this aim\, I used male and female transgenic mice expressing either the human α5-SNP (α5KI mice)\, or a deletion of the CHRNA5 gene (α5KO mice)\, and organized my research work around the three following questions: \n(1) How are these α5 subunit mutations modifying alcohol-drinking behaviour? \n(2) What is the neural substrate of these modifications? Focusing on regions carrying the highest density of α5-nAChR in the brain: the ventral tegmental area (VTA)\, a key component of the reward system and the interpeduncular nucleus (IPN)\, which may mediate a regulation/aversion signal. \n(3) Do α5-subunit mutations modify the preconsummatory traits related to alcohol abuse? Which unfortunately are still poorly assessed in preclinical addiction studies. \nBy combining models of alcohol self-administration and in-vitro electrophysiological recordings of the VTA dopaminergic and the IPN GABAergic neurons\, we found that the lack of α5 subunit results in a functional imbalance in the VTA-IPN circuit\, shifting the alcohol consumption toward high doses in both males and females\, with nevertheless some sex-dependent effects. Using viral neurospecific reexpression\, we obtained further evidence that α5-expressing IPN GABAergic neurons play a critical role in the control of alcohol intake. \nBy testing the α5KI mice\, we found that\, as for the α5 subunit deletion\, the α5-SNP deregulates alcohol consumption: both α5KI and α5KO mice drink larger amount of alcohol at high doses. However\, prior any alcohol exposition\, these two mutant strains display opposite socio-emotional phenotypes. Strickingly\, these are highly consistent with two human alcoholic profiles established by Cloninger and colleagues\, with: the Type I = female\, risk and novelty ‘avoidant’ displaying high anxiety; versus the Type II = male\, ‘sensation seeker’. These data suggest that preclinical models expressing human genetic variants can help to identify different motivations to consume and thus different AUDs subtypes while exploring their neurobiological basis. These could represent a major step toward the development of personalized and thus more effective treatments. \nKeywords: α5 nicotinic acetylcholine receptor subunit; ventral tegmental area; interpeduncular nucleus; transgenic mice; alcohol use disorders; preconsummatory traits. \nPublications\nPublished:\n \nHusson M\, Harrington L\, TOCHON L\, Cho Y\, Ibañez-Tallon I\, Maskos U\, David V (2020).\nβ4-nicotinic receptors are critically involved in reward-related behaviors and self-regulation of nicotine reinforcement.
