ACE2-angiotensin-(1-7)-Mas axis in renal ischaemia/reperfusion injury in rats.

AngII (angiotensin II), ACE (angiotensin I-converting enzyme) and the AT1 receptor (AngII type 1 receptor) are associated with the inflammatory process and microvascular dysfunction of AKI (acute kidney injury) induced by renal I/R (ischaemia/reperfusion). However, Ang-(1-7) [angiotensin-(1-7)], ACE2 (angiotensin I-converting enzyme 2) and the Mas receptor also play a role in renal disease models. Therefore, in the present study, we have examined the renal profile of Ang-(1-7), ACE2 and the Mas receptor in renal I/R and compared them with that of AngII, ACE and the AT1 receptor.
