In Aging Cell, researchers have published their findings that exosomes, which we have previously reported to extend the lives of mice, also extend the lives of rats.
Exosomes, a subset of extracellular vesicles (EVs), can be visualized as messages and packages that cells send to one another. Along with lifespan studies, EVs have been investigated for their ability to treat liver fibrosis, and they have been identified as potential biomarkers of disease [1].
Working with the well-known Steve Horvath, this group had previously found that E5, a specific exosome derived from pigs, reverses biomarkers of aging in rats [2]. This study logically builds upon that one, determining whether or not it actually improves lifespan in these animals.
