Meeting report: ISN forefronts in nephrology on endothelial biology and renal disease: From bench to prevention

Abstract

This ISN-sponsored Forefront in Nephrology meeting, which has brought together 120 scientists from 21 countries, has been concerned with various aspects of endothelial function and dysfunction and their contribution to progression of chronic kidney disease and/or its cardiovascular complications. The following themes were discussed in great depth: (1) phenotypical changes in the vascular endothelium - permeability, senescence, and apoptosis; (2) regulation of endothelial nitric oxide (NO) synthase function - caveolar and shear stress mechanisms, epigenetic regulation, S-nitrosylation, and Rho-kinase regulation; (3) oxidative stress and hypoxia-induced changes; (4) organellar dysfunction - lysosomes, mitochondria, and endoplasmic reticulum; (5) NO-independent mechanisms of vasomotion - epoxides, heme oxygenase-1 and carbon monoxide, thromboxane, tumor necrosis factor-alpha, and uric acid; (6) endothelial crosstalk with podocytes, monocytes, smooth muscle cells, and platelets; (7) candidate clinical biomarkers of endothelial dysfunction - functional testing of macro- and micro-vascular functions, surrogate markers, circulating detached endothelial cells, and endothelial precursor cells; and culminated in Round Table discussion on the diagnosis of endothelial dysfunction and its treatment options. In conclusion, this meeting has focused on several key problems of endothelial cell pathobiology relevant to chronic kidney disease. © 2006 International Society of Nephrology.
