Lisinopril does not exactly "protect" the kidneys. It is helpful, in that lowering blood pressure, helps the kidneys.
But Lisinopril is dependent on good kidney function for clearance from the body, because it is NOT metabolized away by the liver.

Notice the dichotomy of having increased serum creatinine on Lisinopril...? I think that these actions are not well understood and remain confusing.
What lisinopril DOES do is enter the brain easily via the blood brain barrier, and it is thought it protects against inflammation that increases risk of Alzheimer's. This too, is only a theory... but has been published. You can find it on the net.
