Brief description In the healthy body, the kidney and the sympathetic nervous system work together to keep our blood pressure in the normal range, both in the short and long term. When people have kidney disease, this system fails and people can develop high blood pressure. High blood pressure can lead to heart attack and stroke, and so is a serious complication for people who already have kidney disease. It has previously been believed that major factors in this process are fluid retention and a circulating hormone called angiotensin II, but we believe that the sympathetic nervous system is also very important. Further, we believe that sensory nerves in the kidney tell the brain something is wrong in the kidney, making the sympathetic nervous system increase blood pressure inappropriately. We will examine the relative role of the sensory nerves and the hormone angiotensin II in driving the sympathetic nervous system to increase blood pressure, using three different rat models of kidney disease. One of these models is a new rat model of polycystic kidney disease, which is the fourth most important cause of renal disease in Australia. We want to determine what parts of the brain are important in the pathway, and will also test treatments that block the two different pathways (nerves vs. hormones) to see what is the most effective way of controlling not only blood pressure but also slowing down the progression of kidney and heart disease. This work is important as it will not only help us understand how the brain and kidney communicate with each other, but will also have the potential to improve quality of treatment for people with kidney disease
