过氧化物酶体增殖物激活受体-(PPAR-)是脂肪生成、脂代谢、胰岛素敏感性和葡萄糖稳态的重要转录调节因子,在炎症细胞和心血管疾病(如高血压、心肌肥厚、充血性心力衰竭和动脉粥样硬化)中发挥重要作用。PPAR激动剂,噻唑烷二酮类(TZD),在胰岛素抵抗患者和动物模型中增加胰岛素敏感性,降低血糖,减少循环中的游离脂肪酸和甘油三酯,降低血压,减少炎症标志物,并减轻动脉粥样硬化。人类对PPAR的遗传学研究表明,这种核受体的功能变化与心血管疾病有关。最近有争议的临床研究提出了PPAR激动剂对心血管系统有害作用的问题。代谢反应因子和心血管疾病的这些复杂的相互作用有望成为未来的重要关注领域。
Peroxisome proliferator-activated receptor- (PPAR-), an essential transcriptional mediator of adipogenesis, lipid metabolism, insulin sensitivity, and glucose homeostasis, is increasingly recognized as a key player in inflammatory cells and in cardiovascular diseases (CVD) such as hypertension, cardiac hypertrophy, congestive heart failure, and atherosclerosis. PPAR- agonists, the thiazolidinediones (TZDs), increase insulin sensitivity, lower blood glucose, decrease circulating free fatty acids and triglycerides, lower blood pressure, reduce inflammatory markers, and reduce atherosclerosis in insulin-resistant patients and animal models. Human genetic studies on PPAR- have revealed that functional changes in this nuclear receptor are associated with CVD. Recent controversial clinical studies raise the question of deleterious action of PPAR- agonists on the cardiovascular system. These complex interactions of metabolic responsive factors and cardiovascular disease promise to be important areas of focus for the future.
