SIRT3-Boosted Stem Cells Reduce Inflammation, Improve Aged Mice

Summary

Story summary

Raising SIRT3 in blood stem cells cut inflammation-promoting immune cells and improved health in aged mice.
The SIRT3-overexpressing stem cells were transplanted into young mice with weak immunity.
Treated mice ran farther, stayed longer on a screen, and performed better in memory tests and lung function.
Adoptive transfer of immune cells from the SIRT3-enhanced stem cells reproduced benefits, though Danica Chen notes the study is mouse-only and needs human confirmation.
