Funded Activity Summary

The complete loss of kidney function means that survival of the patient is dependent upon lifelong dialysis or a kidney transplant. Dialysis patients have a poor quality of life, and the provision of dialysis and transplantation treatments are very costly. Our current therapies have only limited efficacy and are associated with significant side-effects. Therefore, we need to understanding the way in which the kidney is damaged in disease in order to identify new and specific approaches to the treatment of kidney disease. Our studies have shown that white blood cells, called macrophages, enter the kidney in large numbers during disease. Indeed, the greater the number of macrophages within the kidney, the more severe the kidney injury. We believe, on the basis of animal studies, that these macrophages cause kidney injury. However, we do not know the mechanisms by which this happens. To address this question, we have developed a rat model of kidney disease in which we can take macrophages, which we have cultured in the laboratory, and inject them into animals and they will enter the kidney and cause injury. This allows us to modify specific macrophage functions in culture and then determine whether this affects the ability of these macrophages to cause kidney injury in the animal. In this way, we will be able to understand the mechanisms by which macrophages cause kidney injury. We hope that these studies will can be a starting point for the development of new and specific approaches to the treatment of human kidney disease.
