Longevity Chemical Signaling encompasses the network of molecular messengers, including hormones, peptides, and metabolites, that influence cellular maintenance, repair pathways, and the overall rate of biological aging.
Origin
This terminology is constructed from ‘Longevity,’ referencing extended healthy lifespan, and ‘Chemical Signaling,’ the fundamental means of cellular communication.
Mechanism
Effective signaling involves optimizing pathways such as mTOR, sirtuins, and AMPK, which respond to nutrient status and stress; for example, caloric restriction mimetics function by altering these signals to favor catabolic and repair processes over anabolism.
