Longevity Pathways

Meaning

Longevity pathways are a set of highly conserved, interconnected cellular and molecular signaling cascades that regulate the aging process, cellular repair, and overall lifespan in organisms. These pathways respond dynamically to environmental cues, particularly nutrient availability and stress, influencing genetic expression to prioritize either growth and reproduction or maintenance and survival. Key pathways include mTOR, AMPK, sirtuins, and the insulin/IGF-1 signaling cascade, which are central targets for healthspan and lifespan optimization strategies.
