Electrical Inhibition of Identified Anorexigenic POMC Neurons by Orexin/Hypocretin [PDF]

The Journal of Neuroscience, 2007
Proopiomelanocortin (POMC) neurons of the hypothalamic arcuate nucleus (ARC) suppress appetite, and lack of POMC-derived peptides or electrical silencing of POMC neurons causes obesity. ARC POMC neurons are surrounded by nerve terminals containing the wakefulness-promoting peptides orexins/hypocretins, but whether orexin affects their electrical ...

Central Dicer-miR-103/107 controls developmental switch of POMC progenitors into NPY neurons and impacts glucose homeostasis

eLife, 2018
Proopiomelanocortin (POMC) neurons are major negative regulators of energy balance. A distinct developmental property of POMC neurons is that they can adopt an orexigenic neuropeptide Y (NPY) phenotype.

Calcium Channel CaV2.3 Subunits Regulate Hepatic Glucose Production by Modulating Leptin-Induced Excitation of Arcuate Pro-opiomelanocortin Neurons

Cell Reports, 2018
Summary: Leptin acts on hypothalamic pro-opiomelanocortin (POMC) neurons to regulate glucose homeostasis, but the precise mechanisms remain unclear.

Cellular and synaptic reorganization of arcuate NPY/AgRP and POMC neurons after exercise

Molecular Metabolism, 2018
Objective: Hypothalamic Pro-opiomelanocortin (POMC) and Neuropeptide Y/Agouti-Related Peptide (NPY/AgRP) neurons are critical nodes of a circuit within the brain that sense key metabolic cues as well as regulate metabolism.

Sirt6 in pro-opiomelanocortin neurons controls energy metabolism by modulating leptin signaling

Molecular Metabolism, 2020
Objective: Sirt6 is an essential regulator of energy metabolism in multiple peripheral tissues. However, the direct role of Sirt6 in the hypothalamus, specifically pro-opiomelanocortin (POMC) neurons, controlling energy balance has not been established ...

Glucose rapidly induces different forms of excitatory synaptic plasticity in hypothalamic POMC neurons. [PDF]

PLoS ONE, 2014
Hypothalamic POMC neurons are required for glucose and energy homeostasis. POMC neurons have a wide synaptic connection with neurons both within and outside the hypothalamus, and their activity is controlled by a balance between excitatory and inhibitory

Is there a role for cannabidiol in obesity, metabolic syndrome and binge eating?

British Journal of Pharmacology, EarlyView.
Cannabidiol (CBD) is one of the most abundant phytocannabinoids isolated from the Cannabis sativa plant. CBD is a lipophilic, non‐intoxicating substance that differently from Δ9‐tetrahydrocannabinol (Δ9‐THC) does not present the typical profile of a drug of abuse.

Dopamine-inhibited POMCDrd2+ neurons in the ARC acutely regulate feeding and body temperature

JCI Insight, 2022
Dopamine acts on neurons in the arcuate nucleus (ARC) of the hypothalamus, which controls homeostatic feeding responses. Here we demonstrate a differential enrichment of dopamine receptor 1 (Drd1) expression in food intake–promoting agouti related ...

Trilogy Development of Proopiomelanocortin Neurons From Embryonic to Adult Stages in the Mice Retina

Frontiers in Cell and Developmental Biology, 2021
Proopiomelanocortin-positive amacrine cells (POMC ACs) were first discovered in adult mouse retinas in 2010; however, the development of POMC-ACs has not been studied.

Amylin analogues as a novel perspective in anti‐obesity therapy

British Journal of Pharmacology, EarlyView.
Abstract Public health systems face a major challenge because of the worldwide obesity epidemic. The number of obese individuals has increased dramatically and, even in Switzerland which may be considered a relatively “lean” country, the numbers are alarmingly high and have reached almost 50% of the adult population.
