Ageing is traditionally seen as a progressive process of damage and loss of function that leads to an increase in disease and mortality.
However, recent in vitro studies have shown ways to reverse the ageing process. This study from 2023 concludes that biological age is flexible and can undergo rapid changes in both directions.
At the epigenetic, transcriptomic and metabolomic levels, the researchers found that the biological age of young mice is increased by heterochronic parabiosis and restored after surgical separation. In addition, they also observed transient changes in biological age during major surgical procedures, during pregnancy and in severe COVID-19 in humans and/or mice.
These findings suggest that biological age increases rapidly in response to various forms of stress, but can reverse after a recovery period.
The present study reveals a new dimension of the dynamics of the aging process that should be considered in future studies. The increase in biological age due to stress could represent a measurable and controllable target for future interventions.
