🧬 Can a blood test reveal which cells in your body are aging fastest?
In this fascinating Nature Medicine study, investigators analyzed >7,000 plasma proteins from 60,542 individuals to develop cellular aging clocks for more than 40 cell types. 🔬
Key findings:
🧠Older astrocytes predicted higher Alzheimer's disease risk
💪 Accelerated skeletal muscle aging forecast amyotrophic lateral sclerosis
🚬 Respiratory epithelial aging identified smokers at particularly high lung cancer risk
📈 Accumulated cellular aging strongly predicted mortality
A remarkable step toward measuring biological aging at cellular resolution and identifying both vulnerability and resilience. #Aging #Proteomics #PrecisionMedicine #MedicalPodcasts #Alzheimers #Longevity #Biomarkers
