SUMMARY:Seminar - Baptiste Lacoste
DESCRIPTION: Venue: Centre Broca \n\nBaptiste Lacoste\nUniversity of Ottawa\nhttps://med.uottawa.ca/cellular-molecular/people/lacoste-baptiste \nInvited by Jean-Luc Morel (INCIA) \nTitle\nNon-neuronal underpinnings of altered brain development \nAbstract\nThe Neurovascular Development Research Lab (NDRL) directed by Dr. Baptiste Lacoste (University of Ottawa\, Ontario\, Canada) focuses on the discovery of mechanisms underlying cerebrovascular health\, with the goal of developping new treatments for neurological conditions involving vascular deficiencies. Using state-of-the art approaches\, the NDRL investigates the vascular underpinnings of autism spectrum disorders and the role of glial cells in postnatal cerebrovascular development. The NDRL has recently extended its program to investigate abnormalities in brain metabolism in autism mouse models. Such projects involve mouse genetics\, human-derived stem cells\, primary brain cell cultures\, electron microscopy\, transcriptomic and metabolic profiling\, as well as 3D imaging and advanced structural quantifications. During his seminar\, Dr. Lacoste will summarize their recent work on the role of brain endothelial cells in autism\, and on the control of neurovascular maturation by astrocyte-derived factors. \nReferences\nBéland-Millar A\, Kirby A\, Truong Y\, Ouellette J\, Yandiev S\, Bouyakdan K\, Pileggi C\, Naz S\, Yin M\, Carrier M\, Kotchetkov P\, St-Pierre MK\, Tremblay MÈ\, Courchet J\, Harper ME\, Alquier T\, Messier C\, Shuhendler AJ\, Lacoste B. 16p11.2 haploinsufficiency reduces mitochondrial biogenesis in brain endothelial cells and alters brain metabolism in adult mice.
