Researchers here provide evidence for the inflammatory burden of infection to accelerate the aging of the hematopoietic system responsible for generating blood and immune cells. A greater exposure to infectious disease throughout life may be causing presently irreversible damage in the stem cell populations that produce the immune system. It is already known that restoration of these stem cell populations is an important target for the rejuvenation of the aged immune system, along with regeneration of the thymus and clearance of misconfigured and damaged populations of immune cells. It is unclear as to which of the many potential approaches to rejuvenation of hematopoietic stem cells will first succeed to a useful degree, but it seems likely that some form of cell therapy will be needed, an outright replacement of worn, damaged, and missing cells with…
