    Angiotensin II AT 2 receptor immunocytochemistry in the mouse brain. (A) and (B) Antibody 2818-1 from Epitomics (dilution 1:400). The AT 2 receptor antibody reacts with parenchymal microvessels (indicated with arrowheads in A and B, and in box in panel A) in the cerebral motor cortex from -1.22 mm to Bregma, and the immunocytochemistry is similar in wild-type (WT) (A) and AT 2 knock-out (KO) mice (B). (C) and (D) Antibody sc-9040 from Santa Cruz (dilution 1:2000). The antibody detects ciliated ependymal cells (arrowheads) of the lateral ventricle (V), and the staining is similar in the wild type (C) or knockout mice (D) located at the same coordinates as A and B. (E) and (F): antibody <t>AAR-012</t> from Alomone (dilution 1:3000). In the cerebral motor cortex, the antibody detects cell colocalization with the neuronal marker NeuN (indicated with arrowheads in E and F and in the boxes in panel E). The staining is similar in wild-type (E) and AT 2 receptor knockout (F) mice. Scale bar = 20 µm.

    Schematic diagram illustrating the mechanistic links of Ang II-upregulation of nNOS protein expression in cardiac myocytes. Ang II stimulates AT1R in cardiomyocyte plasma membrane and quickly internalized, leading to activation of cardiac oxidases such as NADPH oxidase. Intracellular ROS, in turn , activates Akt and phosphorylates endogenous eNOS to activate the enzyme. Subsequently, S-nitrosation of AT2R near cysteine 349 residue contributes to AT2R translocation to the plasma membrane and was stimulated by Ang II. This leads to a rise in nNOS protein and NO generation
