Besides, brain Ang II levels have been revealed to be increased in ischemic tissues after stroke, and contribute to neural damage through elevating oxidative stress levels and inducing inflammatory response in the ischemic hemisphere via AT1R. In recent years, new components of RAS have been discovered, including ACE2, Angiotensin-(1–7) [Ang-(1-7)] and Mas, which constitute ACE2-Ang-(1-7)-Mas axis. Here, ANG is linked to stroke disorder.
