Cellular Nutrient Sensing

Meaning

Cellular Nutrient Sensing is the fundamental molecular process by which individual cells detect, interpret, and rapidly respond to the availability and relative abundance of extracellular and intracellular nutrients, including glucose, amino acids, and fatty acids. This intricate sensing mechanism is essential for regulating critical cellular functions such as growth, metabolism, stress response, and the vital processes of repair and survival. It acts as a primary interface between environmental factors, like diet, and internal cellular programming for longevity.
