A Problem Population of Monocytes are Found to be Senescent Cells

The Life Extension Advocacy Foundation volunteers here note an open access paper from earlier this year. The authors characterize a small, problematic population of the immune cells known as monocytes as being senescent cells, having the same character of inflammatory signaling and disruptive behavior as other types of senescent cell. This finding is one of many discoveries emerging from the great expansion of funding and interest in cellular senescence that has taken place in recent years. The accumulation of senescent cells is an important cause of aging and age-related disease, but broad recognition of this point has required a great deal of time and hard work. Now that research in this field has picked up, the consensus on a range of cell types and behaviors, those observed in age-related disease and known to be harmful, is likely to be revised in the direction of the involvement of cellular senescence.

Monocytes are immune cells that can differentiate into macrophages and are involved in the processes of both innate and adaptive immunity. There are three known types of monocytes: classical, intermediate, and nonclassical. The nonclassical ones are the
