What's the talk about?
The relevance of nearly all biogerontology research to combating ageing is restricted to the potential for slowing down the accumulation of molecular and cellular damage that eventually leads to age-related ill-health. Meanwhile, regenerative medicine has been progressing rapidly and is nearing clinical applicability to a wide range of specific conditions.
I argue that we are approaching the point where regenerative medicine can be used against ageing. This would entail not retarding but actually reversing the accumulation of damage. If successful, this would obviously be a far more valuable technology than mere slowing of ageing. However, in order to be successful it must be comprehensive, and some aspects of aging may seem impossible to address in this way. I shall survey the main examples and argue that the ones which contribute to age-related ill-health are, in fact, realistic targets of regenerative interventions.
Dr. Aubrey de Grey is a biomedical gerontologist based in Cambridge, UK, and is the Chief Science Officer of SENS Foundation, a non-profit charity dedicated to combating the ageing process. He is also Editor-in-Chief of Rejuvenation Research, the world’s highest-impact peer-reviewed journal focused on intervention in ageing. His research interests encompass the causes of all the accumulating and eventually pathogenic molceular and cellular side-effects of metabolism (“damage”) that constitute mammalian aging and the design of interventions to repair and/or obviate that damage. He has developed a possibly comprehensive plan for such repair, termed Strategies for Engineered Negligible Senescence (SENS), which breaks aging down into seven major classes of damage and identifies detailed approaches to addressing each one. A key aspect of SENS is that it can potentially extend healthy lifespan without limit, even though these repair processes will probably never be perfect, as the repair only needs to approach perfection rapidly enough to keep the overall level of damage below pathogenic levels. Dr. de Grey has termed this required rate of improvement of repair therapies “longevity escape velocity”.
