Hypothalamic detection of macronutrients via multiple gut-brain pathways
Food intake is tightly regulated by complex and coordinated gut-brain interactions. Nutrients
rapidly modulate activity in key populations of hypothalamic neurons that regulate food …

[HTML][HTML] Nutritive, post-ingestive signals are the primary regulators of AgRP neuron activity
The brain regulates food intake by processing sensory cues and peripheral physiological
signals, but the neural basis of this integration remains unclear. Hypothalamic, agouti …

AgRP neurons can increase food intake during conditions of appetite suppression and inhibit anorexigenic parabrachial neurons
To maintain energy homeostasis, orexigenic (appetite-inducing) and anorexigenic (appetite
suppressing) brain systems functionally interact to regulate food intake. Within the …

Palatability can drive feeding independent of AgRP neurons
Feeding behavior is exquisitely regulated by homeostatic and hedonic neural substrates that
integrate energy demand as well as the reinforcing and rewarding aspects of food …

Obesity causes selective and long-lasting desensitization of AgRP neurons to dietary fat
Body weight is regulated by interoceptive neural circuits that track energy need, but how the
activity of these circuits is altered in obesity remains poorly understood. Here we describe …

Dynamics of gut-brain communication underlying hunger
Communication between the gut and brain is critical for homeostasis, but how this
communication is represented in the dynamics of feeding circuits is unknown. Here we …

Direct modulation of GFAP-expressing glia in the arcuate nucleus bi-directionally regulates feeding
Multiple hypothalamic neuronal populations that regulate energy balance have been
identified. Although hypothalamic glia exist in abundance and form intimate structural …

Hypothalamic control of interoceptive hunger
While energy balance is critical to survival, many factors influence food intake beyond
caloric need or" hunger." Despite this, some neurons that drive feeding in mice are routinely …

Astrocytes control food intake by inhibiting AGRP neuron activity via adenosine A1 receptors
It is well recognized that feeding behavior in mammals is orchestrated by neurons within the
medial basal hypothalamus. However, it remains unclear whether food intake is also under …
