Altos Labs’ scientists present a comprehensive cellular rejuvenation strategy integrating partial Yamanaka factor reprogramming with targeted senolytic clearance and mitochondrial transplantation. Their analysis shows how these approaches synergistically reverse multiple hallmarks of aging, paving the way for unified age-reversal therapies.
Key points
- Cyclic transient expression of Yamanaka factors reverses epigenetic age by up to 30 years in human cells and extends mouse lifespan by 109%.
- Senolytic regimens (dasatinib+quercetin and Bcl-xL inhibitors) selectively clear senescent cells, reducing pro-inflammatory SASP factors in disease models.
- Mitochondrial transplantation and NAD+ restoration enhance ATP production, lower oxidative stress, and improve cognitive and motor function in aged mice.
Why it matters: This integrative cellular rejuvenation framework signifies a paradigm shift, offering combined therapies that may reverse aging hallmarks rather than merely slow their progression.
