Hypothalamic UDP Increases in Obesity and Promotes Feeding via P2Y6-Dependent Activation of AgRP Neurons
Activation of orexigenic AgRP-expressing neurons in the arcuate nucleus of the hypothalamus potently promotes feeding, thus defining new regulators of AgRP neuron activity could uncover potential novel targets for obesity treatment. Here, we demonstrate that AgRP neurons express the purinergic receptor 6 (P2Y6), which is activated by uridine-diphosphate (UDP). In vivo, UDP induces ERK phosphory...
متن کاملMitochondrial Dynamics Controlled by Mitofusins Regulate Agrp Neuronal Activity and Diet-Induced Obesity
Mitochondria are key organelles in the maintenance of cellular energy metabolism and integrity. Here, we show that mitochondria number decrease but their size increase in orexigenic agouti-related protein (Agrp) neurons during the transition from fasted to fed to overfed state. These fusion-like dynamic changes were cell-type specific, as they occurred in the opposite direction in anorexigenic ...
متن کاملSuppression of GHS-R in AgRP Neurons Mitigates Diet-Induced Obesity by Activating Thermogenesis
Ghrelin, an orexigenic hormone released primarily from the gut, signals the hypothalamus to stimulate growth hormone release, enhance appetite and promote weight gain. The ghrelin receptor, aka Growth Hormone Secretagogue Receptor (GHS-R), is highly expressed in the brain, with highest expression in Agouti-Related Peptide (AgRP) neurons of the hypothalamus. We recently reported that neuron-spec...

متن کاملGetting Serious About Musculoskeletal Conditions and Obesity Management
Welcome to the 8th issue of Closing the Gap-the first issue to debut on Eisai's relaunched Closing the Gap website. If you haven't seen the website recently, please take a few minutes to visit and explore it. For over a year, CTG has been assembling a wealth of useful information on obesity and weight management for employers. Now we have worked with Eisai to create a new design for the site th...
