Aging As Loss Of Biological Self-Correction: A Geroscience Framework For Longevity, Inflammaging, And Restored Resilience
A new perspective on aging suggests that it is fundamentally a progressive decline in our body’s ability to fix itself. This concept, termed “biological self-correction,” describes the intricate process by which our systems detect problems, initiate an appropriate response, repair any damage, and then return to a stable state, all while preserving the capacity for future challenges.
This framework doesn’t replace established ideas like homeostasis, which is the body’s way of maintaining stable internal conditions, or resilience, which is the ability to recover from disturbances. Instead, it provides a unifying link, connecting these broader concepts to the specific molecular machinery responsible for dynamic recovery. The authors propose that the effectiveness of this self-correction can be measured by analyzing how our bodies respond to stress, considering factors such as the speed of reaction, the magnitude of disruption, and the rate of recovery.
This integrated view brings together various aspects of aging research, including “inflammaging” (chronic, low-grade inflammation associated with aging), how our bodies sense nutrients, and cellular senescence (when cells permanently stop dividing). By understanding aging through the lens of declining self-correction, we gain a more comprehensive insight into how these diverse biological processes contribute to the overall loss of adaptive capacity and increased vulnerability that comes with age.
