In conclusion, the PAAIs examined (i.e. mTOR loss of function, Ghrhr loss of function, intermittent fasting-based version of dietary restriction) often influenced age-sensitive traits in a direct way and not by slowing age-dependent change. Previous studies often failed to include young animals subjected to PAAI to account for age-independent PAAI effects. However, any study not accounting for such age-independent intervention effects will be prone to overestimate the extent to which an intervention delays the effects of aging on the phenotypes studied. This can result in a considerable bias of our view on how modifiable aging-related changes are. To What Degree Can Cell Therapies Rebuild the Aging Brain? https://www.fightaging.org/archives/2022/11/to-what-degree-can-cell-therapies-rebuild-the-aging-brain/ Repair of the aging brain is perhaps the most important of goals in regenerative medicine. We are the data that is stored in some way within the small-scale structures of our brain tissue, and so the options for outright replacement of brain cells and tissues are somewhat constrained. As a thought experiment, it is in principle possible, given significant progress in biotechnology, to manufacture a cloned body to receive a transplanted brain. All of the steps needed either already happen in nature, such as the growth of bodies without brains, and would need control and direction, or have been crudely demonstrated in animal studies, such as brain transpla...
