Involvement of endothelin in renal processes.
This study examined the effect of various doses of endothelin (from 0.2 to 2 nmol/kg body wt) on regional hemodynamics in conscious unrestrained rats. Normal rats were instrumented chronically with femoral artery and vein catheters and pulsed Doppler flow probes simultaneously on the renal and superior mesenteric arteries and the abdominal aorta. Endothelin induced a biphasic response of mean a...
متن کاملEndothelin in human autoimmune diseases with renal involvement.
Endothelin (ET)-1 is a potent renal vasoconstrictor with pro-inflammatory, profibrotic and mitogenic potential. Animal studies support a pathogenetic contribution of ET-1 and its cognate receptors in several renal manifestations of autoimmune disorders. However, data in humans are limited. The present minireview thus summarizes the observations available in humans. Similar to animal models, ET-...
متن کاملRole of endothelin in chronic renal failure--developments in renal involvement.
Endothelin (ET)-1 is a potent vasoconstrictor with profibrotic and proinflammatory effects. Increasing evidence suggests that ET-1 and its cognate receptors are involved in a variety of progressive renal disorders, including diabetes, hypertension and glomerulonephritis. Several laboratory studies have demonstrated elevated expression of ET-1, which colocalizes with glomerular and tubulointerst...
متن کاملDifferential effects of U46619 on renal regional hemodynamics in the rat: involvement of endothelin.
Many vasoactive agents produce qualitatively similar effects on blood flow in the renal cortex and medulla, evoking reductions or increases in blood flow in both regions. We demonstrated previously that endothelin-1 (ET-1) is an exception because it evoked an increase in medullary perfusion despite a potent cortical vasoconstriction ( Hercule and Oyekan 2000). We report here that U46619 (11,9 e...
متن کاملEndothelin in renal disease: role of endothelin antagonists.
In spite of tremendous progress in the understanding of human disease, the search for new mediators continues as numerous conditions remain poorly understood. In particular in many forms of renal disease, effective and cause-orientated forms of therapy are still lacking. The discovery of new pathogenetic mechanisms often leads to the development of new drugs with previously unknown properties w...
