IMMUNE REGULATION OF GLOMERULONEPHRITIS [ 2000 - 2002 ]

Research Grant

Researchers: Prof Bruce Hall (Principal investigator)

Brief description Glomerulonephritis (Bright's Disease) is the commonest cause of destruction of kidney function that leads to patients requiring artificial kidney treatment (dialysis) and renal transplantation. The glomeruli or filters of the kidney are attacked by inflammation and destroyed. The attack is usually auto-immune, that is the bodys' immune system loses tolerance to kidney tissue and mounts a destructive attack on the glomeruli. In many patients, this attack is mild and resolves with current treatments to dampen the immune response. In others, current treatment is inadequate to dampen the attack and the kidney is destroyed. This research uses experimental models of nephritis to examine how the immune system injures the glomeruli. In particular, how T cells attack and mediate injury. This is a novel concept, as hither to it has been thought antibodies and other factors in the blood (complement) mediate injury. Our group was one of the first to identify T cells mediate injury in forms of glomerulonephritis, previously thought to be solely mediated by antibody and complement. This project will further define which molecules produced by the T cell effect injury of glomeruli. With the potential aim of turning off the T cell attack mechanisms in a more specific way than is achieved by non specific immunosuppressive drugs such as corticosteroids, cytotoxic (anti-cancer) drugs or cyclosporine (an anti-rejection drug). A major part of this project will be to examine the role of cytokines, hormone like molecules that are produced by white cells and mediate injury or regulate other white cells, in effecting injury and in turning off the immune injury.
