Researchers here show that, in a progeroid mouse model that exhibits high levels of cellular senescence and accelerated manifestations of aging, delivering extracellular vesicles harvested from mesenchymal stem cells has much the same effect as ... [Continue Reading]
Tau Knockout in Normal Mice Improves Mitochondrial Function and Slows Cognitive Decline
Tau is involved in Alzheimer's disease and other tauopathies; it is one of the few proteins in the body capable of becoming naturally altered in ways that encourage aggregation of the protein into solid deposits that are toxic to cells. Tau is highly ... [Continue Reading]
The Tripartite Phenotype of Aging
Here, researchers advocate for a greater consideration of the role of random chance at the cellular level in the variations in life span exhibited by individuals of any given species. Why do people age at different rates and why does human life span ... [Continue Reading]
