最近的研究已经揭示了过氧化物酶体增殖物激活受体(PPAR)家族转录因子在血压调节中的作用,扩大了PPAR配体的可能治疗用途。PPARα和PPARγ调节肾素-血管紧张素-醛固酮系统(RAAS),RAAS是通过转录控制肾素、血管紧张素原、血管紧张素转换酶(ACE)和血管紧张素II受体1(AT-R1)来调节全身血压和间质液量的主要调节剂。阻断RAAS是高血压治疗的一个重要靶点,可减轻高血压患者的微血管损伤、肾小球炎症和左心室肥厚,并显示出抗糖尿病作用。RAAS抑制获益的潜在机制似乎涉及PPARγ调节途径。本文综述了PPARs在RAAS转录调控中的作用以及PPARs配体在RAAS依赖性高血压治疗中的应用。
Recent research has revealed roles for the peroxisome proliferator activated receptor (PPAR) family of transcription factors in blood pressure regulation, expanding the possible therapeutic use of PPAR ligands. PPARα and PPARγ modulate the renin-angiotensin-aldosterone system (RAAS), a major regulator of systemic blood pressure and interstitial fluid volume by transcriptional control of renin, angiotensinogen, angiotensin converting enzyme (ACE) and angiotensin II receptor 1 (AT-R1). Blockade of RAAS is an important therapeutic target in hypertension management and attenuates microvascular damage, glomerular inflammation and left ventricular hypertrophy in hypertensive patients and also show antidiabetic effects. The mechanisms underlying the benefits of RAAS inhibition appear to involve PPARγ-regulated pathways. This review summarizes current knowledge on the role of PPARs in the transcriptional control of the RAAS and the possible use of PPAR ligands in the treatment of RAAS dependent hypertension.
