Molecular rejuvenation strategies are a class of advanced clinical and scientific interventions explicitly designed to reverse or significantly slow the accumulation of molecular damage that defines the cellular and tissue aging process. These strategies target the fundamental hallmarks of aging at the subcellular level, aiming to restore youthful cellular function, enhance intrinsic repair mechanisms, and improve overall tissue resilience. The ultimate goal is to extend healthspan by resetting the biological clock of the organism.
Origin
This term is a cornerstone of geroscience and translational longevity medicine, emerging from the scientific classification of the nine distinct molecular and cellular hallmarks of aging. Rejuvenation strategies represent a proactive and precise application of molecular biology to clinical practice. The concept shifts the focus from treating age-related diseases to treating the underlying process of aging itself.
Mechanism
Strategies mechanistically involve modulating key longevity pathways, such as activating sirtuins and AMPK, restoring NAD+ levels, clearing senescent cells via senolytics, or enhancing autophagy. These interventions directly influence gene expression, mitochondrial biogenesis, and proteostasis, effectively reprogramming cellular behavior towards a younger phenotype. The hormonal system is often involved, as many longevity pathways are intimately linked to nutrient-sensing and stress-response hormones.
