University of Iowa researchers have shown that a protein channel helps nerve sensors in blood vessels keep blood pressure in check. Without the protein channel, known as ASIC2, the sensors are unable to send the brain the signals it needs to properly control blood pressure.

The finding, which was based in animal models, is important because it could be used to create new treatments to prevent high blood pressure. According to Dr. Frank Abboud, "By knowing more about what makes these sensors malfunction, we may be able to find ways to make them work properly and prevent high blood pressure." The study results appear in the journal Neuron.
