Story summary
- Studies from Karolinska Institutet show somatic mutations in muscles and vascular tissues contribute to age-related decline.
- Higher mutation burden negatively affects muscle recovery and strength, linking genetic changes to sarcopenia and frailty in older adults.
- Insights into these mutations could inform new treatments for degenerative diseases and support healthy aging.
