New review maps how ROS-induced fibroblast senescence disrupts the extracellular matrix, fuels chronic inflammation, and accelerates aging across the body.
Three things to remember
- ROS accumulation triggers fibroblast senescence and SASP-mediated inflammation.
- Senescent fibroblasts disrupt ECM homeostasis, reducing dermal thickness and elasticity.
- Nrf2, mTOR, TGF-β, and IGF-1 pathways regulate these aging processes.
