Ablation of AgRP neurons impairs adaption to restricted feeding
While the SCN controls the circadian clock, further evidence suggests the existence of a food-entrainable oscillator (FEO) that links behavior to changes in food availability such as during restricted feeding (RF). We found that the activity of AgRP/NPY neurons changed rhythmically during RF suggesting that these neurons are a component of the FEO.

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 ...

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.

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
Objective: An environmental context, which reliably predicts food availability, can increase the appetitive food drive within the same environment context.

AgRP Accountants Compute Caloric Cost [PDF]
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.

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-

GIRK2 potassium channels expressed by the AgRP neurons decrease adiposity and body weight in mice.
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
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 ...

The gut signals to AGRP-expressing cells of the pituitary to control glucose homeostasis
Glucose homeostasis can be improved after bariatric surgery, which alters bile flow and stimulates gut hormone secretion, particularly FGF15/19. FGFR1 expression in AGRP-expressing cells is required for bile acids’ ability to improve glucose control.
