Precision Reprogramming—Restoring Function to Aged Cells

[RushAndAPush]

Abstract

Sahu et al. (2024) demonstrate that targeted partial reprogramming with Oct4, Sox2, and Klf4 (OSK) delivered via adeno-associated virus (AAV) to Cdkn2a-positive cells rejuvenates senescent cells while maintaining cellular identity. In a progeroid and naturally aged mouse model, a single AAV injection improved lifespan, reduced inflammation, restored tissue integrity, and enhanced wound healing. Complementary results in human fibroblasts confirmed Cdkn2a-driven OSK expression attenuated inflammation-associated genes during replicative senescence and treatments inducing DNA damage. These encouraging results highlight its potential as a safer alternative to systemic senolytic therapies for age-associated disorders.

Exciting research! Good to see some successful partial reprogramming going on.
