Protein levels of angiotensin receptors in Alzheimer’s dementia groups. (A) Protein levels of angiotensin II type 1 receptor (AT₁R). (B) Angiotensin II type 2 receptor (AT₂R). (C) Angiotensin type 4 receptor (AT₄R) in Alzheimer’s dementia (AD) group treated (n = 30) and untreated (n = 30) with angiotensin receptor blockers (ARB). Data are presented with median and interquartile range. Comparisons were conducted using Mann–Whitney U test (*p ≤ 0.05). au, arbitrary unit. (D) Western blot images of the AT₁R, AT₂R, and AT₄R
