摘要
脂蛋白(a)[Lp(a)]是动脉粥样硬化(As)形成与进展的高危因素,血浆中高浓度的Lp(a)已成为公认的冠心病预测因子。研究表明,与Lp(a)相连的氧化磷脂(OxPL)成分可能是其致AS的关键因素,而与Lp(a)相连的另一个组分——脂蛋白相关磷脂酶A2(LV—PLA2)可水解OxPL,其水解产物溶血磷脂酰胆碱(Lyso.PC)和游离氧化脂肪酸(oxFFA)是促进AS发生发展的重要炎症因子。脂蛋白相关磷脂酶A2水解脂蛋向(a)连接的氧化磷脂可产生炎性因子,促进动脉粥样硬化的发生发展。OxPL和Lp—PLA2可作为心血管疾病(CVD)新靶标,具有潜在预测指标的临床应用价值。
Lipoprotein ( a ) [ Lp ( a ) ] is considered a causal risk factor for the formation and development of atherosclerosis (AS). High plasma levels of Lp (a) is recognized as a predictor of coronary heart disease. However, the pathogenic mechanisms of Lp (a) are still unknown. Recent studies demonstrated that a key role in the proatherogenic effects of Lp ( a ) may be linked to its oxidized phospholipids (OxPL) content. Lipoprotein-associated phospholipase A2 (Lp-PLA2) is another important factor in Lp(a) functionality. OxPL are hydrolyzed by Lp-PLA2 into lysophosphatidylcholine (lyso-PC) and oxidized free fatty acid (OxFFA) , which are important inflammatory factors on promoting the occurrence and development of AS. The present review article describes Lp-PLA2 hydrolyzing OxPL associated with Lp(a). The process induces inflammatory factors, which promote development of AS. OxPL and Lp-PLA2 can be used as new targets of cardiovascular diseases, which have clinical application value to predict potential cardiovascular diseases . (
