What is the Origin of Longevity Biomarker?

The term is foundational to the field of geroscience, where the need to quantify biological age necessitates observable, quantifiable indicators. It is derived from the concept of a biomarker, adapted to focus specifically on the temporal progression of senescence. These indicators help personalize anti-aging strategies.

What is the Mechanism of Longevity Biomarker?

Many longevity biomarkers track cumulative cellular damage or the efficiency of protective systems, such as DNA repair or proteostasis. For instance, markers reflecting telomere attrition or accumulation of lipofuscin indicate reduced cellular replicative capacity. Optimizing the hormonal environment, particularly by supporting growth factors and reducing chronic cortisol exposure, can favorably influence the trajectory of these markers.

Longevity Biomarker

Meaning

A specific, measurable biological characteristic that correlates reliably with the rate of aging or the expected remaining healthspan of an individual, independent of chronological age. These markers provide critical feedback on the effectiveness of interventions aimed at slowing or reversing age-related physiological decline. Examples include methylation patterns or specific circulating metabolites.
