This paper isn’t open access, but is important enough to stand out from the many publications on clearance of senescent cells emerging these days. While the evidence is compelling for senescent cells to be a root cause of aging, and removal of senescent cells via senolytic therapies to reverse aspects of aging, many of the fine details remain to be robustly established in the science and the implementations. Measures of senescent cell levels are not yet advanced enough for clinical implementations, for example, and the life span studies have so far involved animals genetically modified to suppress senescence rather than administration of senolytics to normal animals. That has now changed: in this study, researchers demonstrate that the senolytic mix of dasatinib and quercetin produces noteworthy results on the remaining life span of old mice.

Physical dysfunction and incapacity to respond to stresses become increasingly prevalent toward the end of life, with up to 45% of people over the age of 85 being frail. The cellular pathogenesis of age-related physical dysfunction has not been fully elucidated, and there are currently no root cause-directed, mechanism-based interventions for improving physical function in the
