Researchers at the University of Virginia School of Medicine have identified a group of nerve cells in the brainstem that act as a stabilizing system for blood pressure. The findings suggest these cells help prevent fluctuations when the body shifts between everyday activities and that their loss or dysfunction could contribute to blood pressure instability in certain conditions.

Why it matters

Excessive short-term variability in blood pressure is a strong predictor of heart disease, stroke and brain injury, so understanding the mechanisms that regulate blood pressure stability is crucial. This research could open the door to new treatments to help stabilize blood pressure and prevent harmful effects.

The details

The research team found that the loss of just a few hundred of these nerve cells in the brainstem leads to unstable blood pressure, even when the average blood pressure appears normal. Similar brain-based mechanisms could contribute to blood pressure instability in other conditions where average blood pressure seems fine based on standard measurements.

  • The research findings were published in the scientific journal Circulation Research in February 2026.

What they’re saying

“What we found is that a loss of just a few hundred nerve cells leads to unstable blood pressure even though the mean blood pressure was normal. This shows that the system that keeps blood pressure steady from moment to moment is no longer working.”

— Stephen Abbott, Lead Investigator (Circulation Research)

“Our work emphasizes a new appreciation for how we think about blood pressure problems. It's not just about lowering the numbers – it's about keeping blood pressure stable from moment to moment.”

— Stephen Abbott, Lead Investigator (Circulation Research)

What’s next

The researchers plan to further investigate how the identified nerve cells in the brainstem regulate blood pressure stability and explore potential treatments that could target this system.

The takeaway

This research provides important insights into the brain's role in maintaining stable blood pressure, which is crucial for preventing serious cardiovascular and neurological complications. The findings could lead to new approaches for managing blood pressure issues beyond just lowering the numbers.
