Nesfatin-1 neurons are a population of hypothalamic and brainstem neurons that express and secrete the anorexigenic peptide nesfatin-1, derived from the precursor protein nucleobindin-2 (NUCB2). These neurons play crucial roles in regulating feeding behavior, energy homeostasis, mood, stress responses, and autonomic functions. Nesfatin-1 was first identified in 2006 as a satiety molecule that suppresses food intake through a leptin-independent mechanism, making it an important target for understanding energy balance and metabolic disorders.
Nesfatin-1 neurons are strategically positioned throughout the hypothalamus and brainstem, allowing them to integrate multiple signals related to energy status, stress, and environmental cues. These neurons project to key appetite-regulating centers, including the arcuate nucleus, paraventricular nucleus, and lateral hypothalamic area, where they modulate the activity of neurons that control feeding.
Nesfatin-1 is a 30-amino acid peptide derived from the 420-amino acid precursor protein nucleobindin-2 (NUCB2). The precursor undergoes proteolytic processing by the secretory granule convertases PC1/3 and PC2 to generate mature nesfatin-1:
The receptor for nesfatin-1 was identified as GPR173, a G-protein coupled receptor (GPCR) expressed in hypothalamic nuclei. Upon binding:

Potential therapeutic uses include:
Nesfatin-1 neurons represent a critical population of hypothalamic and brainstem neurons that regulate feeding, energy balance, stress responses, and mood. Derived from the NUCB2 precursor, nesfatin-1 acts through GPR173 to exert its anorexigenic effects, working in concert with but independently of leptin. These neurons integrate metabolic, neural, and hormonal signals to maintain homeostasis, and their dysfunction contributes to eating disorders, depression, and metabolic diseases. Understanding nesfatin-1 biology may provide therapeutic targets for conditions ranging from obesity to neurodegeneration.
