This field of scientific inquiry focuses on biological strategies designed to restore cellular and physiological functions to a state characteristic of a younger chronological age. The primary objective is not merely to extend lifespan but to significantly compress the period of age-related decline, thereby increasing healthspan. This involves targeted manipulation of fundamental aging hallmarks, aiming for a measurable biological age reduction. Clinical trials often explore novel therapeutic agents or lifestyle interventions that influence key molecular pathways. The ultimate goal is to translate these findings into clinically viable protocols for human longevity.
Origin
The concept draws its roots from the established fields of gerontology and regenerative medicine, gaining significant momentum with the discovery of epigenetic clocks and a deeper understanding of cellular reprogramming. Its etymological origin combines the clinical term “age” with the biological goal of “reversal,” signifying a shift from slowing aging to actively undoing age-associated damage. The term is heavily utilized within the longevity and biohacking communities to describe experimental interventions targeting fundamental biological processes. This research area represents a paradigm shift from treating age-related disease symptoms to addressing the root cause of aging itself.
Mechanism
Mechanisms under investigation typically involve epigenetic modulation, senolytic clearance of senescent cells, and restoration of mitochondrial function. These interventions aim to recalibrate the body’s homeostatic set points, often targeting endocrine signaling pathways that become dysregulated with time. For instance, manipulating growth hormone or insulin-like growth factor signaling is a central hormonal strategy. Furthermore, optimizing NAD+ metabolism and enhancing proteostasis are crucial cellular processes being explored for their potential to drive systemic biological rejuvenation.
