UVA researchers have unlocked a critical mechanism in blood pressure control. They discovered that smooth muscle cells, key players in regulating blood pressure, can switch to producing renin when pressure drops — a revelation that could revolutionize hypertension treatment. This biological “switch” offers new insights into vascular diseases and the potential for novel medications.The findings, published by News Directory 3, detail how the renin gene’s accessibility allows for rapid responses, perhaps mitigating side effects of existing treatments while providing a pathway to better understand how the body maintains healthy blood pressure. Discover what’s next as research continues to refine hypertension strategies and manage vascular disease.
UVA Researchers Discover Key Mechanism in Blood Pressure Control
Updated June 10, 2025
Researchers at the University of virginia School of Medicine have made a notable finding regarding how certain cells can alter their function to help regulate blood pressure control. The study sheds light on the role of smooth muscle cells, which line arteries and typically manage blood pressure through contraction and relaxation.
When blood pressure decreases significantly for extended periods, these smooth muscle cells, along with some kidney cells, can start producing renin. Renin, a substance usually made in specialized kidney cells, is crucial for maintaining blood pressure. The research team has identified a critical biological “switch” that governs this shift to renin production, explaining the cells’ ability to adapt.
R. Ariel Gomez, MD, of UVA’s Child Health Research Center, saeid that understanding this switch could lead to new medications for high blood pressure and vascular diseases.The team’s work, including collaborators Maria Luisa S. Sequeira-Lopez, MD, and Jason P. Smith, PhD, focused on how cells “remember” to make renin long after they have stopped.
The researchers identified nine genes playing key roles in the biological pathways that regulate renin production. These genes control both the cessation and resumption of renin production in smooth muscle cells.While these cells naturally stop producing renin, they remain ready to reactivate when needed.
Smith noted that the region in the genome where the renin gene is located remains accessible, even when renin production is off.This accessibility allows cells to quickly resume production when more renin is required. A better understanding of how the body controls renin production could be foundational in treating hypertension and mitigating the long-term effects of blood pressure medications on kidney function.
“Discovering how the switch works will help us understand how our bodies control blood pressure,” said researcher R. Ariel Gomez, MD, of UVA’s Child Health Research Center. “Knowing how vascular cells change their identity could help develop new medications to treat high blood pressure and vascular diseases.”
Sequeira-Lopez emphasized the importance of understanding the basic secrets of cells to design more effective therapies with fewer adverse effects. the research provides a thorough map of renin regulation, offering direction for future studies and insights into kidney damage, potentially leading to new treatments for cardiovascular disease.
What’s next
The researchers aim to identify markers and potential targets to mitigate unwanted effects of chronic renin cell stimulation, potentially leading to new treatments for high blood pressure and cardiovascular disease.
