What is the Origin of Longevity Signaling?

This term is derived from the field of geroscience, merging the concept of extended healthy lifespan (longevity) with the communication processes (signaling) that govern cellular fate. It reflects a shift toward engineering biological durability.

What is the Mechanism of Longevity Signaling?

Key signaling nodes include the Insulin/IGF-1 pathway, mTOR, and AMPK, all of which interact closely with metabolic hormones like insulin and growth hormone. For instance, caloric restriction mimetics often work by biasing signaling toward catabolic, repair-focused states. Maintaining balanced activation of these longevity signals is essential for preserving endocrine system function into later life stages.

Longevity Signaling

Meaning

Longevity Signaling refers to the network of intracellular pathways activated by nutrient availability, cellular stress, and hormonal status that collectively influence the rate of aging and lifespan. Optimizing these signals directs cellular resources toward maintenance and repair rather than rapid growth or proliferation. We are looking for the molecular pathways that favor long-term biological resilience.
