Nutrient Signaling

Meaning

Nutrient signaling is the complex molecular process by which cells detect, interpret, and respond to the availability and concentration of macronutrients and micronutrients within the cellular environment. This system acts as a master metabolic switch, translating dietary input into fundamental physiological decisions regarding cell growth, proliferation, energy storage, and repair. Key pathways involved, such as mTOR and AMPK, are directly influenced by nutritional status, profoundly impacting cellular longevity and hormonal sensitivity.
