In humans and other multicellular organisms, cells multiply. This defining feature allows embryos to grow into adulthood, and enables the healing of the many bumps, bruises and scrapes along the way.
Certain factors can cause cells to abandon this characteristic and enter a zombie-like state known as where they persist but no longer divide to make new cells. Senescent cells also are prone to secreting inflammatory molecules that can contribute to chronic inflammation in the body. This inflammation brings greater risk for age-related diseases.
Scientists at Sanford Burnham Prebys and collaborators across the country published findings March 5, 2025, in Nature Communications showing that the mitochondria powering our cells also control the ability of a DNA repair protein to suppress the secretion of inflammatory molecules by senescent cells.
With additional research, it may be possible to design a treatment based on these findings to promote healthier aging. Read more: https://vist.ly/3mxd3yw
