  • Deletion of Mfn2 in endothelial cells (ECs) triggers a mitohormetic response, improving systemic metabolism and healthspan in mice.
  • Mfn2 deficiency in ECs enhances antioxidant defenses, mitochondrial fitness, and lipid oxidation, leading to better metabolic outcomes.
  • ECs secrete GDF15 via a FOXO1-dependent axis, observed both in vitro and in vivo under stress conditions.
  • Mfn2i��EC mice showed elevated GDF15 levels, and GDF15 neutralization partly reversed metabolic benefits.
  • Mfn2i��EC mice were protected against diet-induced obesity and age-related decline, highlighting vascular mitohormesis as a novel health-promoting mechanism.
