The acute effect of FK506 and cyclosporine on endothelial cell function and renal vascular resistance.


We have previously documented that cyclosporine exerts a direct cytotoxic effect on endothelial cells and causes an increase in renal vascular resistance (RVR) in the rat. In the present study we investigated whether FK506, a novel immunosuppressive agent thought to be less nephrotoxic than CsA, impairs endothelial cell function in vitro and affects RVR in… (More)
