Activation of the Lactate Receptor GPR81 Ameliorates Senescence Hallmarks and Improves Muscle Function in Cellular and Progeroid Models of Aging.
Activating a lactate receptor reverses age-related muscle damage and improves muscle regeneration in aging mice, pointing to a new sarcopenia target.
This study establishes GPR81 (the lactate receptor) as a key regulator of skeletal muscle lipid metabolism during aging: GPR81 knockdown in young myoblasts recapitulates senescence phenotypes, while GPR81 agonist treatment of senescent cells reverses lipid accumulation and restores mitochondrial function. In progeric mice, GPR81 agonist treatment significantly improved muscle regeneration, identifying GPR81 as a novel druggable target for sarcopenia and age-related myopathy.

Why it surfaced
Novel GPR81 axis for muscle aging—pharmacologically tractable target with in vivo proof-of-concept in a progeroid model; sarcopenia has no approved pharmacotherapy and massive population health burden.
