Arcuate Npy Neurons In Neurodegeneration is an important cell type in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
The arcuate nucleus (ARC) of the hypothalamus contains several key neuronal populations, including neuropeptide Y (NPY)/agouti-related peptide (AgRP) neurons. These neurons are primary regulators of energy homeostasis and are critically involved in metabolism, appetite, and stress responses.
- Metabolic dysfunction: NPY/AgRP neuron abnormalities contribute to metabolic syndrome in AD 1
- Amyloid effects: Amyloid-beta alters hypothalamic energy regulation 2
- Stress axis: NPY neurons modulate HPA axis in AD 3
- Appetite disturbances: Anorexia and weight loss in AD 4
- Metabolic disturbances: Weight loss and metabolic dysfunction 5
- Appetite regulation: Dysregulation of food intake 6
- Stress response: Altered NPY signaling 7
- Energy homeostasis: NPY system dysfunction in HD 8
- Metabolic deficits: Weight loss and cachexia 9
- Neurotransmitters: NPY, AgRP, GABA
- Function: Orexigenic, promotes food intake
- Activity: Activated by energy deficit
- Projections: PVN, LHA, brainstem
- Neuropeptides: α-MSH, β-endorphin
- Function: Anorexigenic, reduces food intake
- Activity: Activated by energy surplus
- Leptin signaling: ARC neurons respond to leptin
- Insulin signaling: Metabolic regulation
- Ghrelin effects: Hunger hormone signaling
- HPA axis modulation: NPY modulates cortisol response
- Anxiety regulation: NPY has anxiolytic effects
- Reward pathways: Interaction with mesolimbic system
- NPY receptor agonists: Y1, Y5 receptor targeting
- Leptin therapy: Metabolic modulation
- AgRP antagonism: Appetite regulation
