Late-life semaglutide treatment slows ageing and extends lifespan in female mice.

Nature·September 1, 2026·PMID 42686906

Why it matters

GLP-1 receptor agonists are widely used for diabetes and obesity, but their broader effects on ageing are unclear. This study provides mechanistic evidence that semaglutide acts as a calorie restriction mimetic, slowing ageing and extending lifespan in female mice, which may explain its pleiotropic benefits and support investigation in human ageing.
