Angiotensin II (Ang II) has long been considered the major bioactive effector molecule of the renin–angiotensin system and is recognized as a major contributor to hypercholesterolaemia-induced atherosclerosis [1,2]. LDL-receptor-deficient and apoE-deficient mice have been intensively investigated in this regard. Chronic Ang II infusions in such mice accelerate atherosclerosis and promote aneurysm formation [3]. Angiotensin converting enzyme (ACE) inhibitors and angiotensin AT1 receptor blockers (ARB) reduce the atherosclerotic lesion size [3]. The results would suggest that reduced Ang II levels and decreased signalling through AT1 receptors are responsible for the salubrious effects of these drugs. However, some have argued that perhaps increased signalling via AT2 receptors in the case of ARB or perhaps the bioactive angiotensin peptides Ang III, Ang IV or Ang (1–7) play a role. The latter molecule is said to exert protective effects by
