🧬 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
