AGTR2 and neurodegenerative disease: It is made up of two axes: one is the Angiotensin II Type 1 receptor (AT1R) or Angiotensin II Type 2 receptor (AT2R), while the other is angiotensin-(1-7) [Ang-(1-7)], and Mas receptor; the latter has reported developing a neuroprotective effect; oppositely, AT1R activation has been linked to neurodegenerative diseases.
