EFFECTOR AND REGULATORY INTERSTITIAL INFLAMMATORY CELLS IN CHRONIC PROTEINURIC RENAL DISEASE

Funded Activity Summary

Current treatments for chronic kidney disease are ineffective. As a consequence, kidney failure progresses to the stage where patients require dialysis or transplantation to remain alive. Every year almost 1600 Australians commence dialysis for this reason, and many more die of kidney failure or its complications. This project will lead to a greater understanding of why kidney failure progresses, and will define more effective treatments for preventing progression. In progressive chronic kidney diseases of all types, the supporting tissue within the kidney (the interstitium) becomes infiltrated with inflammatory cells. The amount of interstitial inflammation has an important bearing on the severity of kidney failure, and the rate at which kidney disease progresses to endstage. The reasons that these inflammatory cells infiltrate the interstitium, and their exact role in the progression of kidney disease are only partially understood. For example, some of these inflammatory cells appear to cause kidney scarring, whereas others appear to be protective. Moreover, even though they are obvious targets for treatment aimed at slowing the progression of kidney disease, current treatments are largely ineffective as they do not differentiate between the different types of inflammatory cells, and whether these cells are causing or preventing damage. Our laboratory has recently developed a robust model of chronic kidney disease, which will be used to examine the effect of individual types of interstitial inflammatory cells on the progression of kidney disease. So far we have shown that depletion of one type of inflammatory cell (CD4 lymphocytes) worsened the disease process, whereas depletion of two other cell types (CD8 lymphocytes or macrophages) was protective. This raises the real and exciting possibility that treatment directed against specific inflammatory cells may be effective in the treatment of progressive kidney disease in humans.
