Neuromedin N is primarily involved in the regulation of gastrointestinal and central nervous system functions. It acts as a neurotransmitter and neuromodulator, influencing gut motility and secretion. In research, it is used to study its role in appetite regulation and energy balance, potentially contributing to understanding obesity and metabolic disorders. Additionally, it is investigated for its effects on pain perception and stress responses, offering insights into neurological and psychiatric conditions. Its application in animal models helps explore its physiological and pathological roles, aiding in the development of therapeutic strategies for related diseases.
