Clinical studies have provided ample evidence that inhibition of the RAS with ACE inhibitors and/or AT1-receptor blockers is an effective strategy in slowing the progression of chronic renal disease [13]. Although it was initially thought that inhibition of the RAS is renally protective through haemodynamic mechanisms (for example by reduction of hyperfiltration), it is now clear that angiotensin II (ANG II) is a multifactorial cytokine exhibiting growth stimulatory, proinflammatory and profibrotic effects [46]. These more pleiotrope effects of ANG II on the kidney were initially greeted with some skepticism [5]. At a time when the specific receptors for ANG II have only just been cloned and the ANG II-receptor blocker, saralasin, was only recently replaced with more specific agents, these reservations were not surprising [6].
ANG II binds to various receptors [6]. The AT1-subtype is involved in many
