The accumulation of senescent cells with age causes age-related disease and dysfunction. The most important factor driving this accumulation may be the decline of the immune system, as immune cells are responsible for cleaning up the tiny fraction of all senescent cells that fail to self-destruct, but that has yet to be determined with any great rigor. Regardless of the reasons for this accumulation, periodic removal of senescent cells has been shown to improve health and extend life span in mice, as well as reverse specific aspects of tissue aging in a variety of organs. Therefore a great deal of interest is currently focused on finding new and better ways to go about the targeted destruction of senescent cells. That starts with further mining of the biochemistry of these cells, such as in the research results noted here.

There are at present a limited number of proven approaches to senolytic therapies, those that can selectively destroy senescent cells without causing any great harm to normal cells. Immunotherapy targeting surface markers on senescent cells, as at SIWA
