Animal model observation may reveal new cause of hypertension — ScienceDaily

High blood pressure: some people take medication to control it while others commit to low salt diets, exercise or yoga to reduce stress. Blood pressure is a primary vital sign, yet, remarkably, just how the body maintains it is still a mystery.

“We’ve been studying high blood pressure for 100 years and we still have the same ideas,” says Daniel Beard, Ph.D., the Carl J. Wiggers Collegiate Professor of Cardiovascular Physiology. In a new paper in JCI Insight, Beard, Feng Gu, Ph.D., from the department of molecular and integrative physiology, and their team describe a newly observed phenomenon in the way blood pressure is maintained in certain rats.

Their discovery comes on the heels of an inquiry into the linkage between stiffened arteries and high blood pressure, known clinically as hypertension. “What happens when you are hypertensive is your arteries get stiffer. But this is thought to be an
