Neuropeptide W-23 (NPW-23) is primarily involved in regulating energy homeostasis and feeding behavior. It acts as a signaling molecule in the brain, influencing appetite and metabolic processes. Research suggests its potential role in modulating stress responses and anxiety-related behaviors, making it a candidate for studying neuropsychiatric disorders. Additionally, NPW-23 has been explored for its effects on cardiovascular functions, including blood pressure regulation. Its interaction with specific receptors in the central nervous system highlights its significance in understanding neural pathways and developing therapeutic interventions for metabolic and neurological conditions.
