In addition to blood pressure regulating, ACE2 is involved in the pathophysiological processes by converting angiotensin isozymes during cell injury. ACE2 converts angiotensin II to angiotensin‑(1‑7).http://ijpm.mui.ac.ir/index.php/ijpm/article/view/2316http://ijpm.mui.ac.ir/index.php/ijpm/article/download/2316/717718158
