    Schematic diagram of signal transduction pathways involved in Ang II-induced endothelial hyperpermeability via AT1R/RAGE/mDia1/Src/β-catenin/VE-cadherin. a As Ang II binds to and stimulates AT1R, the expression and secretion of HMGB1 can be increased by NF-κB activation. NF-κB-mediated expression of proinflammatory molecules, including RAGE itself, can occur. HMGB1 binds to RAGE, which can induce RAGE-mediated activation of Src/β-catenin/VE-cadherin via mDia1. b Blockade of RAGE activation by sRAGE attenuates the Ang II-induced increase in endothelial hyperpermeability by inhibiting RAGE-mediated signaling pathways

    The possible pathways of Ang II-mediated angiogenesis. ANG II stimulates the generation of ROS through membrane NAD(P)H oxidases in VSMCs after binding to AT1-R. ROS are involved in many Ang II mediated effects, including production of HIF-1α in vascular cells, activation of p38MAPK, and transcription factor NF-kB. Interactions between Ang II and ROS are critical in vascular physiology and pathology in terms of regulating vascular structure and functions. Ang-Tie could also trigger the production of ROS through NADPH oxidase.

    Angiotensin II-induced neuroinflammation and oxidative stress are mediated by kinin B1R. Mouse neonatal primary hypothermic neurons express both B1R and AT1R. Ang II stimulation of neurons increased expression of B1R, which in turn increased resulted in upregulation of Nox2 and Nox4 expression, and NF-κB activation, and ultimately leading to expression of pro-inflammatory cytokine production. Treatment with R715, the specific B1R antagonist blunted angiotensin II-induced neuroinflammation and oxidative stress by reducing Nox gene expression and attenuating NF-κB activation.

    Angiotensin II AT 1A receptor mRNA, AT 1 receptor binding and protein in wild-type, and AT 1A knock-out mice ( a ): expression of mRNAs was studied by RT–PCR in kidney cortex, liver, and adrenal gland of wild-type and AT 1A knock-out mice. Gene expression was normalized to the level of 18S rRNA, and represents the mean ± SEM. of three individual determinations. Note that AT 1A mRNA is not expressed in kidney cortex and liver of AT 1A knock-out mice. AT 1B mRNA is not expressed in liver of wild-type or knock-out mice, but it is expressed in adrenal gland of both wild-type and AT 1A knock-out mice ( b, c ): AT 1 receptor expression was studied by quantitative autoradiography in sections from kidney cortex ( b ) and from the hypothalamus ( c ) containing the PVN (–0.7 mm from bregma), incubated in the presence of 0.25 nM [ 125 I] Sar 1 –Ile 8 –angiotensin II as described in “Materials and Methods”. Figures represent a typical result repeated in three different AT 1A knock-out and wild-type mice. Note abundant receptor binding in the kidney cortex, predominantly localized to kidney glomeruli, and in the PVN of wild-type mice, completely displaced by incubation with the AT 1 receptor-specific antagonist losartan (non-specific binding) and the complete absence of binding in the kidney cortex and PVN of AT 1A knockout mice (d): Ang II AT 1 receptor protein expression was studied by western blotting.

    The possible pathways of Ang II-mediated angiogenesis. ANG II stimulates the generation of ROS through membrane NAD(P)H oxidases in VSMCs after binding to AT1-R. ROS are involved in many Ang II mediated effects, including production of HIF-1α in vascular cells, activation of p38MAPK, and transcription factor NF-kB. Interactions between Ang II and ROS are critical in vascular physiology and pathology in terms of regulating vascular structure and functions. Ang-Tie could also trigger the production of ROS through NADPH oxidase. Ang II, angiotensin II; Ang-Tie, angiopoietin-Tie; AT1-R, angiotensin II type 1 (AT1) receptor; HIF-1α, hypoxia inducible factor-1α; NF-kB, nuclear factor kappa AB; ROS, reactive oxygen species; VSMCs, vascular smooth muscle cells.

    Angiotensin II-induced neuroinflammation and oxidative stress are mediated by kinin B1R. Mouse neonatal primary hypothermic neurons express both B1R and AT1R. Ang II stimulation of neurons increased expression of B1R, which in turn increased resulted in upregulation of Nox2 and Nox4 expression, and NF-κB activation, and ultimately leading to expression of pro-inflammatory cytokine production. Treatment with R715, the specific B1R antagonist blunted angiotensin II-induced neuroinflammation and oxidative stress by reducing Nox gene expression and attenuating NF-κB activation.
