产品说明书产品使用指南

Angiotensin II (Angiotensin II) 是一种血管收缩剂，是肾素/血管紧张素系统的主要生物活性肽。Angiotensin II human 在调节人类血压中起着核心作用，主要通过血管紧张素 II 与 G 蛋白偶联受体 (GPCRs)、血管紧张素II 1型受体 (AT1R) 和血管紧张素II 2型受体 (AT2R) 之间的相互作用来介导。Angiotensin II human 刺激交感神经刺激，增加醛固酮生物合成和肾脏活动。Angiotensin II human 诱导血管平滑肌细胞生长，增加成纤维细胞中 I 型和 III 型胶原的合成，导致血管壁和心肌增厚，并导致纤维化。Angiotensin II human 也诱导细胞凋亡 (apoptosis)。Angiotensin II human 通过 LOX-1 依赖的氧化还原敏感途径诱导内皮细胞毛细血管形成。

生物活性

Angiotensin II (Angiotensin II) is a vasoconstrictor and a major bioactive peptide of the renin/angiotensin system. Angiotensin II human plays a central role in regulating human blood pressure, which is mainly mediated by interactions between Angiotensin II and the G-protein-coupled receptors (GPCRs) Angiotensin II type 1 receptor (AT1R) and Angiotensin II type 2 receptor (AT2R). Angiotensin II human stimulates sympathetic nervous stimulation, increases aldosterone biosynthesis and renal actions. Angiotensin II human induces growth of vascular smooth muscle cells, increases collagen type I and III synthesis in fibroblasts, leading to thickening of the vascular wall and myocardium, and fibrosis. Angiotensin II human also induces apoptosis. Angiotensin II induces capillary formation from endothelial cells via the LOX-1 dependent redox-sensitive pathway.

体外研究

Most of the known actions of Angiotensin II (Ang II) are mediated by AT1 receptors, the AT2 receptor contributes to the regulation of blood pressure and renal function
. Angiotensin II raises blood pressure (BP) by a number of actions, the most important ones being vasoconstriction, sympathetic nervous stimulation, increased aldosterone biosynthesis and renal actions. Other Angiotensin II actions include induction of growth, cell migration, and mitosis of vascular smooth muscle cells, increased synthesis of collagen type I and III in fibroblasts, leading to thickening of the vascular wall and myocardium, and fibrosis. These actions are mediated by type 1 Ang II receptors (AT₁).
Angiotensin II (1 nM) induces the expression of LOX-1 and VEGF and enhances capillary formation from human coronary endothelial cells in Matrigel assay. Angiotensin II -mediated expression of LOX-1 and VEGF, capillary formation, intracellular reactive oxygen species generation, and phosphorylation of p38 as well as p44/42 mitogen-activated protein kinases, are suppressed by anti-LOX-1 antibody, nicotinamide-adenine dinucleotide phosphate oxidase inhibitor apocynin and the Ang II type 1 receptor blocker Losartan, but not by the Ang II type 2 receptor blocker PD123319.

体内研究

Angiotensin II human (5 mL of 1 nM; intraperitoneal injection; 200-250 g Sprague-Dawley rats) induces a significant neutrophil recruitment that was maximal at 4 hours and had resolved by 24 hours.
To distinguish the AT₁ receptor population that is critical for the pathogenesis of hypertension, osmotic minipumps are implanted s.c. into each animal to infuse Angiotensin II (1000 ng/kg/min) continuously for 4 weeks. Angiotensin II causes hypertension by activating AT₁ receptors in the kidney promoting sodium reabsorption.
