by Noah Brown, Massachusetts General Hospital Credit: Cell (2023). DOI: 10.1016/j.cell.2023.02.033 Aging (senescent) cells, which stop dividing but don’t die, can accumulate in the body over the years and fuel chronic inflammation that contributes to conditions such as cancer and degenerative disorders. In mice, eliminating senescent cells from aging tissues can restore tissue balance and lead to an increased healthy...

Scientists reverse aging process in rat brain stem cells
by University of Cambridge New research, published today in Nature, reveals how increasing brain stiffness as we age causes brain stem cell dysfunction, and demonstrates new ways to reverse older stem cells to a younger, healthier state. The results have far reaching implications for how we understand the ageing process, and how we might develop...

Research shows it’s possible to reverse damage caused by aging cells
What’s the secret to aging well? University of Minnesota Medical School researchers have answered it- on a cellular level. Credit: CC0 Public Domain Aging starts in our cells, and those aging cells can hasten cellular senescence, leading to tissue dysfunction and related health impacts. New research involving University of Minnesota Medical School faculty Paul D. Robbins and Laura J....

Mitochondrial Peptides: Their Effect on Aging
Published 07/25/18 Mitochondria have long been recognized as the metabolic powerhouse in the body, and their functionality is critical to a number of processes. Interestingly, in recent years their role in signaling is being consistently appreciated. Thus, identifying reading frames that encode peptides has been a crucial component of research. One peptide that has been a huge...

Key molecule of aging discovered
Every cell and every organism ages sooner or later. But why is this so? Scientists at the German Cancer Research Center in Heidelberg have now discovered for the first time a protein that represents a central switching point in the aging process. It controls the lifespan of an individual—from the fly to the human being. This opens...

Researchers Have Found a “Reset Button” for Aging Cells
IN BRIEF Induced pluripotent stem (iPS) cells may be the key to reversing aging in hematopoietic stem cells. The technique is also particularly useful for combating blood-related cancers and other disorders. FIGHTING DISEASE BEFORE IT STRIKES From revitalizing heartbeats and increasing longevity, to removing disorders via gene editing, blood-borne challenges are approached with new solutions as quickly as we can innovate them....
