This study investigated the effects of long-term aerobic exercise on physical function and gene expression regulation in young and old male C57BL/6J mice. A comprehensive single-cell transcriptomic atlas was constructed integrating exercise, aging, and acute infectious challenges across multiple tissues/organs. The researchers found that exercise conferred broad health benefits, including improved physical performance, reduced inflammation, and protection against acute severe infection in young mice. In aged mice, exercise reversed aging-related gene expression changes and associated phenotypes. The study identified BMAL1 as a central mediator of exercise-driven geroprotective effects, coordinating downstream circadian genes in multiple tissues and cell types.
