生物活性 | 血管緊張素ⅱ(血管緊張素ⅱ)是一種血管收縮劑和腎素-血管緊張素系統(tǒng)的主要生物活性肽。血管緊張素ⅱ人類中起著重要的作用在調(diào)節(jié)人體血壓,主要由血管緊張素ⅱ和G-protein-coupled受體之間的相互作用(GPCRs)血管緊張素ⅱ1型受體(AT1R)和血管緊張素ⅱ2型受體(AT2R)。血管緊張素ⅱ人類刺激交感神經(jīng)的刺激,增加醛固酮生物合成和腎的行動(dòng)。人類血管緊張素ⅱ誘導(dǎo)的血管平滑肌細(xì)胞,增加膠原蛋白I型和III在成纖維細(xì)胞合成,導(dǎo)致血管壁增厚和心肌纖維化。血管緊張素ⅱ人類也誘發(fā)細(xì)胞凋亡。血管緊張素ⅱ誘導(dǎo)形成毛細(xì)血管內(nèi)皮細(xì)胞通過(guò)LOX-1依賴redox-sensitive途徑。. | ||||||||||||||||

體外研究 (In Vitro) | 大多數(shù)已知的血管緊張素ⅱ(Ang II)行動(dòng)由AT1受體介導(dǎo),at?受體有助于調(diào)節(jié)血壓和腎臟功能[1] MCE has not independently confirmed the accuracy of these methods. They are for reference only. | ||||||||||||||||
體內(nèi)研究 (In Vivo) | 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[4]. MCE has not independently confirmed the accuracy of these methods. They are for reference only. | ||||||||||||||||
