Brain inflammation
Researchers have devised a method of reducing brain inflammation by creating a long-lasting inhibitor of the inflammatory factor NF-κB. Targeting inflammaging at its roots This study, published in the Nature journal Experimental & Molecular Medicine, begins with a discussion of age-related chronic inflammation (inflammaging) and its contributions to aging. Specifically, the researchers focus on neuroinflammation,...
An exosome filled with protein-based information.
In Cell Metabolism, researchers have described how a microRNA (miRNA) derived from exosomes generated by human embryonic stem cells (hESCs) restores function and fights senescence in cell cultures and mice. Looking for a better senomorphic Why We Age: Cellular SenescenceAs your body ages, more of your cells become senescent. Senescent cells do not divide or...

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. Known to be effective Exosomes, a subset of extracellular vesicles (EVs), can be visualized as messages and packages that cells send to one another. Along with lifespan studies,...
Ruptured garbage bag
A new paper elaborates on how and why microglia fail to clean up the α-synuclein protein of Parkinson's disease, gradually making the disease worse. The aggregation of Parkinson's Why We Age: Loss of ProteostasisThe loss of proteostasis is the failure of the protein-building machinery of the cell and the accumulation of misfolded proteins, which is...
Happy pig
A new study used a plasma fraction from young pigs to robustly reduce the biological age of old rats. This could potentially open doors to rejuvenation in humans [1]. The blood connection People have been trying to use young blood to rejuvenate old organisms for millennia, but only in recent years has this concept been...
Resarchers publishing in Aging have found that extracellular vesicles (EVs) derived from human umbilical cord mesenchymal stem cells (MSCs) reduce inflammatory markers in chondrocytes, which are responsible for building and maintaining human cartilage. An established approach This is far from the first attempt at treating osteoarthritis using stem cells. We have previously reported on a...
