How aging changes the kidney's control of blood pressure

Official title: Regulation of kidney function and blood pressure in aging

Funded at University of Tennessee Health Sci Ctr · NIH-11321218 · Data updated 2026-11-12

This work looks at whether tiny kidney-derived particles called renal stem cell exosomes help keep kidneys working and blood pressure normal in older adults.

Who could benefit from this research

Could help

People older adults with age-related kidney dysfunction or salt-sensitive hypertension would be the most relevant candidates for follow-up studies or future therapies.

Less likely to help

Patients whose blood pressure problems are unrelated to kidney salt handling or who are younger without age-related kidney changes may not benefit directly from this work.

What this research studies

As people age, kidney function and blood pressure control often worsen, and this project focuses on a possible cause: changes in renal stem cell-derived exosomes. The team will isolate these exosomes and study how they affect kidney cells and salt handling using laboratory and physiological models. They will compare exosome levels and effects in younger versus older systems to see if reduced exosomes link to age-related salt sensitivity and hypertension. Findings will aim to clarify whether restoring or targeting these exosomes could prevent or reverse age-related kidney problems and high blood pressure.

Why it matters

Potential benefit: If successful, this could point to new ways to prevent or treat age-related kidney decline and salt-sensitive high blood pressure by targeting exosomes.

How similar studies have gone: Some preclinical research shows exosomes can influence kidney cells, but applying renal stem cell exosomes to age-related salt sensitivity and hypertension is a relatively new approach.
