Nutrient-sensing cells

Nutrient-sensing cells are specialized biological units, such as gut enteroendocrine cells, pancreatic beta cells, and hypothalamic neurons, that detect and respond to dietary components like glucose, amino acids, and lipids (Gribble & Reimann, 2016). These cells function as metabolic chemosensors, converting chemical signals into hormonal or neural outputs to maintain systemic energy homeostasis (Efeyan et al., 2015). While Nutrient-sensing cells is a descriptive term for a cell population rather than a single molecular target, the specific receptors and enzymes within these cells—such as GPR119, the calcium-sensing receptor, and mTOR—are major focuses of drug development (Schwartz et al., 2013). Therapeutic agents targeting these pathways are primarily used to treat metabolic disorders, including type 2 diabetes and obesity, by enhancing satiety or improving insulin secretion. However, because these sensing mechanisms are often broadly expressed, pharmacological intervention can lead to off-target effects or gastrointestinal complications.
