In the lung, ACE converts angiotensin I (ANG I) into ANG II, which acts as a vasopressor and a mitogen for smooth muscle cells and fibroblasts through the angiotensin 1 (AT1) receptor. By contrast, ACE2 [53] converts ANG I and ANG II into angiotensin (1–9) and angiotensin (1–7), respectively, which cause vasodilatation and apoptosis through the AT2 receptor 3, 51.
