Indoxyl Sulfate Induces Leukocyte-Endothelial Interactions through Up-regulation of E-selectin

Despite a positive correlation between chronic kidney disease and atherosclerosis, the causative role of uremic toxins in leukocyte-endothelial interactions has not been reported. We thus examined the effects of indoxyl sulfate, a uremic toxin, on leukocyte adhesion to activated endothelial cells and the underlying mechanisms. Pretreatment of human umbilical vein endothelial cells (HUVEC) with indoxyl sulfate significantly enhanced the adhesion...
