Biomedicines, 2023 Neuronal circuits regulating appetite are dominated by arcuate nucleus neurons, which include appetite-promoting and -suppressing neurons that release the orexigenic neuropeptide agouti-related protein (AgRP) and anorexigenic neuropeptide pro ...

AgRP Accountants Compute Caloric Cost [PDF]
Cell Reports, 2017 The gut-brain communication underlying energy homeostasis has been a topic of interest for years. In two new papers, Beutler et al. (2017) and Su et al. (2017) delve into the mechanisms by which satiation is represented in a well-studied population of orexigenic neurons.

Frontiers in Physiology, 2020 The orexigenic agouti-related protein (AgRP) and the anorexigenic pro-opiomelanocortin (POMC) are crucial players in the control of feed intake in vertebrates, yet their role in teleosts has not been fully established.

Molecular Metabolism, 2023 Objective: The learned associations between sensory cues (e.g., taste, smell) and nutritive value (e.g., calories, post-ingestive signaling) of foods powerfully influences our eating behavior [1], but the neural circuits that mediate these associations ...

Acute inhibition of hunger-sensing AgRP neurons promotes context-specific learning in mice
Molecular Metabolism, 2023 Objective: An environmental context, which reliably predicts food availability, can increase the appetitive food drive within the same environment context.

eLife, 2022 Agouti-related peptide (AgRP) neurons increase motivation for food, however, whether metabolic sensing of homeostatic state in AgRP neurons potentiates motivation by interacting with dopamine reward systems is unexplored. As a model of impaired metabolic-

Differential Signaling Profiles of MC4R Mutations with Three Different Ligands [PDF]
, 2020 The melanocortin 4 receptor (MC4R) is a key player in hypothalamic weight regulation and energy expenditure as part of the leptin-melanocortin pathway. Mutations in this G protein coupled receptor (GPCR) are the most common cause for monogenetic obesity,

GIRK2 potassium channels expressed by the AgRP neurons decrease adiposity and body weight in mice.
PLoS Biology, 2023 It is well known that the neuropeptide Y (NPY)/agouti-related peptide (AgRP) neurons increase appetite and decrease thermogenesis. Previous studies demonstrated that optogenetic and/or chemogenetic manipulations of NPY/AgRP neuronal activity alter food ...

AgRP neurons are not indispensable for body weight maintenance in adult mice
Cell Reports, 2023 Summary: In addition to their role in promoting feeding and obesity development, hypothalamic arcuate agouti-related protein/neuropeptide Y (AgRP/NPY) neurons are widely perceived to be indispensable for maintaining normal feeding and body weight in ...

Charge Characteristics of Agouti-Related Protein Implicate Potent Involvement of Heparan Sulfate Proteoglycans in Metabolic Function. [PDF]
, 2019 The endogenous melanocortin peptide agouti-related protein (AgRP) plays a well-known role in foraging, but its contribution to metabolic regulation is less understood.
