Researchers have once again demonstrated that a senolytic therapy capable of selectively destroying senescent cells can reduce tau aggregation and consequent loss of cognitive function in a mouse model of Alzheimer’s disease. The research materials noted below report on the use of navitoclax, also known as ABT-263, in mice and follow very closely on the heels of two other studies that produced very similar results using different senolytic treatments, piperlongumine in one study and the dasatinib / quercetin combination in the other. This is very characteristic of research into the removal of senescent cells: any approach that succeeds in destroying a significant fraction of senescent cells produces significant gains in health; there is no shortage of different approaches; the treatments employed cost very little and are easily purchased in the global marketplace; and researchers can readily replicate the findings of other groups. This a very robust intervention in the aging process, producing data that is far more consistent than any other approach I am aware of.
Why does the removal of senescent cells work so well? Firstly, there are few of these cells, perhaps a few percent
