Brief description Kidney failure is a major health problem in our community, affecting the lives of several thousand individuals and their families. Every year in Australia, about 2,000 new individuals commence dialysis and require ongoing treatment for the rest of their lives. The significant negative impact kidney failure has on quality of life and on life expectancy added to the major shortage of transplant organs, makes the development of effective therapies for kidney diseases an important goal. Our current therapies have major limitations in terms of their effectiveness and side effects. New therapies which can prevent the progression of kidney disease or prolong the survival of transplanted kidneys may, therefore, have enormous benefits. In order for this to occur, an improved understanding of the common factors underlying kidney disease is required. Our recent studies have been examining the factors influencing kidney inflammation. This process is a significant cause of long term damage in various kidney diseases and in kidney transplants. Our work has identified a potentially major role for recently discovered molecules known as Slit proteins in preventing or decreasing inflammation in the kidney. The level of expression of these molecules in the kidney appears to be rapidly decreased in kidney inflammation and their protective effect is then lost. This imbalance appears to promote the disease process and may be a useful target for the treatment of certain kidney diseases. Our work has found that Slit proteins are able to decrease the movement of white cells (the cells which cause inflammation) out of the blood circulation and into the kidney. The proposed studies aim to better understand the role of these molecules in the kidney as naturally expressed anti-inflammatory agents and to test their potential as therapeutic agents. We hope that the information obtained from these studies will help in the development of new therapies to manage various forms of kidney disease.
