Corinne Leloup,Corinne Leloup,Corinne Leloup,Camille Allard,Camille Allard,Camille Allard,Lionel Carneiro,Lionel Carneiro,Lionel Carneiro,Xavier Fioramonti,Xavier Fioramonti,Xavier Fioramonti,Stephan Collins,Stephan Collins,Stephan Collins,Luc Pénicaud,Luc Pénicaud,Luc Pénicaud +17 more
TL;DR: Growing evidence suggest that astrocytes form a complex network and have to be considered as spatially coordinated and regulated metabolic units in physiological and pathological states.

TL;DR: A hypothalamic alteration of DRP1-induced fission and mROS signaling in response to glucose was observed in HGS-induced IS of rats exposed to a 3 week HFHS diet.

O47: Modification précoce de la détection hypothalamique du glucose lors d’un régime gras et sucré : rôle de la dynamique mitotochondriale
Lucie Desmoulins,Chloé Chrétien,Stephan Collins,Audren Fournel,Sylvie Grall,Camille Allard,Claude Knauf,Xavier Fioramonti,Luc Pénicaud,Corinne Leloup +9 more
TL;DR: In this paper, the authors investigated the effect of a regime gras et sucre (HFHS) on the sensitivity of the hypothalamus to glucose, and quantifiant l'adressage de DRP1 (fission) a la mitochondrie, ainsi que l’activite respiratoire des mitochondries par oxygraphie.
Alteration of hypothalamic glucose and lactate sensing in 48 h hyperglycemic rats

TL;DR: Results indicate that hypothalamic sensing of circulating lactate triggers insulin secretion and both glucose and lactate sensing are altered in a model of hyperglycemia, without alteration of MBH MCTs protein levels.
