Negligible Senescence Species Do Not Eliminate Cellular Aging—They Outclean It

clarwin· Feb 27, 2026

This infographic contrasts how typical cells accumulate damage with age versus the naked mole-rat's strategy of maintaining consistently high cellular cleanup (autophagy and proteasome activity) from birth, leading to exceptional longevity.

Naked mole-rats live 30+ years without apparent aging, not because they stop cellular damage, but because they maintain youthful levels of autophagy and proteasome activity throughout life. Newborn pups already show higher autophagy markers than adult mice.

The mechanism: sustained cellular housekeeping that keeps protein quality high from birth. This suggests longevity interventions might work better by enhancing cleanup systems rather than preventing damage entirely.
