Exploring the role of β2-microglobulin in the relationship between physical activity and DNAm-predicted PhenoAge: Evidence from a population-based and mice single-cell RNA-sequencing study
{{output}}
Introduction: Physical activity (PA) is recognized as a cornerstone of healthy aging, yet the molecular mechanisms linking PA to biological aging remain poorly understood. β2-microglobulin (β2M), an inflammatory and aging bioma... ...
