Characterizing Brain Angiotensin System
Peter Abadir, MD Johns Hopkins University
This study is designed to evaluate specific factors that may play a role in development and progression of Alzheimer’s Dementia. Angiotensin receptors 1, 2 and 4 (AT1R, AT2R and AT4R) are found on brain cells and play an important function in brain vital functions. This study will examine changes in these receptors in brain cells in patients with Alzheimer’s dementia. We will also study the impact of a class of drugs that target these receptors and commonly used to treat high blood pressure.
