Arcuate Nucleus Pomc Neurons is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Overview
Arcuate Nucleus POMC Neurons are a specialized cell type classified within the Neuron > Neuropeptide > Arcuate > POMC lineage. These cells are primarily found in Arcuate nucleus of hypothalamus and are characterized by expression of marker genes including POMC, CART (CARTPT), LEPR, NPY. They are selectively vulnerable in Alzheimer's Disease, Metabolic disorders, Prader-Willi Syndrome. <!-- multi-taxonomy-enrichment -->
