What is the Origin of Endogenous Repair Pathways?

This concept is central to the biology of aging and longevity science, stemming from the understanding that cellular damage is a continuous, inevitable byproduct of aerobic metabolism. The term emphasizes the body's innate, self-correcting systems that have evolved to maintain genomic and proteomic integrity. Clinical interventions in this space are designed to amplify or reactivate these naturally occurring restorative mechanisms.

What is the Mechanism of Endogenous Repair Pathways?

The pathways are regulated by a complex network of signaling molecules, many of which are sensitive to systemic hormonal and metabolic states. Hormones such as growth hormone and insulin-like growth factor 1 (IGF-1) play roles in promoting protein synthesis and tissue regeneration. Furthermore, metabolic states induced by interventions like intermittent fasting can activate sirtuins and AMP-activated protein kinase (AMPK), which in turn upregulate DNA repair and initiate the autophagic clearance of damaged organelles, thereby sustaining cellular vitality.

Endogenous Repair Pathways

Meaning

The collection of intrinsic biochemical and cellular processes within the human body responsible for detecting, mitigating, and reversing molecular damage caused by metabolic stress, oxidative species, and genetic errors. These pathways are fundamental to tissue maintenance, cellular longevity, and the prevention of age-related functional decline. Key examples include DNA repair mechanisms, protein quality control systems like autophagy, and the cellular senescence clearance processes.
