Rôle de la détection centrale des lipides dans le contrôle nerveux de la balance énergétique
Abstract
Fatty acid sensitive neurons located in hypothalamus, hippocampus or striatum are able to detect daily variations of plasma fatty acid levels. Thus, these neurons play a role to regulate energy balance by controling food intake, insulin secretion or hepatic glucose production. Molecular mechanisms that mediate fatty acid effects include receptor FAT (fatty acid transporter)/CD36. Deregulation of this brain lipid sensing may be an early event leading to further dysfunction of energy balance leading to obesity and type 2 diabetes.
