          Abstract

          Proteinuria is one of the most potent risk factors for renal disease progression in patients with glomerular diseases. Studies in disease models have helped to delineate mechanisms leading to renal structural damage due to persistent dysfunction of the glomerular barrier to proteins, even when the primary immune or nonimmune insult to the kidney has ceased. The main focus of this review is the role of the tubular epithelial cell in the induction of interstitial inflammatory and fibrogenic reactions to ultrafiltered proteins. Antiproteinuric drugs (angiotensin–converting enzyme inhibitors, ACEi) while preserving the integrity of the glomerular permselective barrier limit both proteinuria and protein–dependent processes which contribute to tubulointerstitial injury, and in so doing ACEi halt the progression of proteinuric nephropathies toward terminal renal failure.

            RANTES and Monocyte Chemoattractant Protein–1 (MCP-1) Play an Important Role in the Inflammatory Phase of Crescentic Nephritis, but Only MCP-1 Is Involved in Crescent Formation and Interstitial Fibrosis

            The involvement of chemokines in inflammation is well established, but their functional role in disease progression, and particularly in the development of fibrosis, is not yet understood. To investigate the functional role that the chemokines monocyte chemoattractant protein–1 (MCP-1) and RANTES play in inflammation and the progression to fibrosis during crescentic nephritis we have developed and characterized a murine model for this syndrome. Significant increases in T-lymphocytes and macrophages were observed within glomeruli and interstitium, paralleled by an induction of mRNA expression of MCP-1 and RANTES, early after disease initiation. Blocking the function of MCP-1 or RANTES resulted in significant decreases in proteinuria as well as in numbers of infiltrating leukocytes, indicating that both MCP-1 and RANTES (regulated upon activation in normal T cells expressed and secreted) play an important role in the inflammatory phase of crescentic nephritis. In addition, neutralization of MCP-1 resulted in a dramatic decrease in both glomerular crescent formation and deposition of type I collagen. These results highlight a novel role for MCP-1 in crescent formation and development of interstitial fibrosis, and indicate that in addition to recruiting inflammatory cells this chemokine is critically involved in irreversible tissue damage.
