Adipose-specific GH signaling modulation improves metabolic resilience in aging, suggesting a new anti-aging strategy.
Our findings identify adipose-specific GH signalling antagonism as a regulatory switch that recalibrates the local balance between GH and IGF-1 actions, thereby reprogramming adipose tissue to promote coordinated systemin metabolic resilience during aging. This tissue-targeted strategy circumvents the developmental and endocrine limitations associated with global GH/IGF-1 suppression. Rather than merely extending lifespan, adipose-specific GHR ablation supports healthier aging by preserving metabolic homeostasis, maintaining multisystem functional integrity and reducing age-associated inflammatory and fibrotic remodelling. Collectively, these results highlight a potentially translatable approach for mitigating age-related metabolic and cognitive decline.
