Metabolic Signaling

Meaning

The complex network of intercellular and intracellular communication pathways that regulate the body’s energy balance, nutrient processing, and resource allocation in response to caloric intake and expenditure. This system involves a dynamic interplay of hormones, neuropeptides, and nutrient sensors, such as insulin, ghrelin, leptin, and adiponectin. Effective metabolic signaling is fundamental to maintaining stable body weight and preventing chronic diseases.
