Hypothalamic arcuate nucleus NPY/AgRP neurons are orexigenic neurons that drive food intake and regulate energy homeostasis. These neurons are the primary regulators of appetite and are implicated in metabolic diseases and neurodegenerative conditions.
Hypothalamic Arcuate NPY Neurons are orexigenic neurons in the arcuate nucleus of the hypothalamus that co-express neuropeptide Y (NPY) and agouti-related peptide (AgRP). Key marker genes include NPY (neuropeptide Y), AGRP (agouti-related peptide), POMC (proopiomelanocortin), CART (cocaine- and amphetamine-regulated transcript), and LEPR (leptin receptor).
