Abstract: The renin-angiotensin system (RAS) and its active peptide angiotensin II (AngII) have major involvements not only in
hypertension but also in mood and anxiety disorders. Substantial evidence supports the notion that AngII acts as a neuromodulator in
the brain. In this review, we provide an overview of the link between the RAS and anxiety or mood disorders, and focus on recent
advances in the understanding of AngII-linked, NADPH oxidase-derived oxidative stress in the central nervous system, which may
underlie pathogenesis of mood and anxiety disorders. (IJPPP1112002).
