Barrett M, Pan Y, Murrell C, Karolczak E, Wang J, Fang L, et al.
bioRxiv
. 2024 Nov;
PMID: 39484373
Diets that are high in fat cause over-eating and weight gain in multiple species of animals, suggesting that high dietary fat is sufficient to cause obesity. However, high-fat diets are...

Metabolic sensing in AgRP regulates sucrose preference and dopamine release in the nucleus accumbens
Reichenbach A, Dempsey H, Andrews Z
J Neuroendocrinol
. 2024 Apr;
36(5):e13389.
PMID: 38599683
Hunger increases the motivation for calorie consumption, often at the expense of low-taste appeal. However, the neural mechanisms integrating calorie-sensing with increased motivation for calorie consumption remain unknown. Agouti-related peptide...

Mol Metab
. 2023 Oct;
78:101826.
PMID: 37898450
Objective: The sensory detection of food and food cues suppresses Agouti related peptide (AgRP) neuronal activity prior to consumption with greatest suppression occurring in response to highly caloric food or...

Mol Metab
. 2023 Sep;
77:101803.
PMID: 37690518
Objective: An environmental context, which reliably predicts food availability, can increase the appetitive food drive within the same environment context. However, hunger is required for the development of such a...

Biol Psychiatry
. 2022 Nov;
93(4):309-321.
PMID: 36400605
Background: A greater understanding of how the brain controls appetite is fundamental to developing new approaches for treating diseases characterized by dysfunctional feeding behavior, such as obesity and anorexia nervosa....

Endocrinology
. 2022 Jul;
163(8).
PMID: 35788848
The ventromedial hypothalamic (VMH) nucleus is a well-established hub for energy and glucose homeostasis. In particular, VMH neurons are thought to be important for initiating the counterregulatory response to hypoglycemia,...

PMID: 35018884
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...

PMID: 33779547
Feeding is critical for survival, and disruption in the mechanisms that govern food intake underlies disorders such as obesity and anorexia nervosa. It is important to understand both food intake...

PMID: 33103129
Blood-borne factors regulate adult hippocampal neurogenesis and cognition in mammals. We report that elevating circulating unacylated-ghrelin (UAG), using both pharmacological and genetic methods, reduced hippocampal neurogenesis and plasticity in mice....

PMID: 29932868
Hunger-sensing agouti-related peptide (AgRP) neurons ensure survival by adapting metabolism and behavior to low caloric environments. This adaption is accomplished by consolidating food intake, suppressing energy expenditure, and maximizing fat...
