New Blood Pressure Index Estimates Arterial Stiffness from Routine 24-Hour Monitoring
Researchers have created tau-SI, a simple arterial stiffness index computable from routine 24-hour blood pressure monitoring data that correlates moderately-to-strongly ...
Aging Extracellular Matrix Emerges as Active Driver of Vascular Aging
A new review argues that the aging extracellular matrix actively reprograms vascular cells, driving endothelial dysfunction, senescence and arterial stiffening.
Scientists map how human blood vessels age cell by cell across the body
An international team has built an atlas of vascular aging, the Human Aging Endothelial Cell Atlas, by analyzing gene activity ...
Diseased Blood Vessels May Drive Fibrosis Across Multiple Organs
A new review argues that dysfunctional blood vessels, through failed endothelial quiescence, abnormal remodeling modes and disrupted angiocrine signaling, may ...
Women’s Pulse Pressure Rises Earlier Than Men’s, Framingham Analysis Finds
A long-term Framingham Heart Study analysis found that women’s pulse pressure began rising about 10 years earlier than men’s, with ...
Massive Cell Atlas Reveals How Aging Blood Vessels Lose Their Regenerative Power
An integrated single-cell atlas of more than 375,000 endothelial cells from 12 human tissues identifies conserved transcriptional hallmarks of vascular ...
MTR4 study links a protein to vascular aging in cells and animals
Blood vessels do more than carry blood: the endothelial cells lining them regulate inflammation, blood flow, tissue repair and the ...
Eating Within a Window: How Time-Restricted Feeding Keeps Aging Arteries Young
A new study in Aging Cell shows that time-restricted feeding delays vascular aging in mice by remodeling the gut microbiota ...
Vascular Receptor TLR4 Emerges as a Master Switch Between Vascular Aging and Targeted Senotherapeutics
A new review in Aging Cell positions endothelial TLR4 as a context-dependent molecular rheostat controlling vascular senescence, arguing that precision ...
Vitamin C Infusion Restores Aging Brain Blood Vessel Function in Small Trial
A randomized crossover trial found that high-dose intravenous vitamin C improved cerebrovascular reactivity in middle-aged and older adults but not ...
The Dark Side of Good Cholesterol: Rogue HDL Particle Drives Arterial Aging
Scientists have identified an electronegative HDL subfraction enriched in apolipoprotein(a) that induces endothelial senescence through the p53–p21 pathway and accelerates ...
Fingertip Scan Reveals Hidden Heart Health in People Over 80
A new GeroScience study used OCTA imaging and machine learning to show that the microscopic blood vessels at the fingernail ...
Dermal Macrophage Loss Drives Skin Capillary Aging
Recent groundbreaking research reveals a fascinating new approach to combat age-related deterioration of skin capillaries by reversing the decline of ...
