我们讨论了卵磷脂的生物化学的最新发现:胆固醇酰基转移酶(LCAT),LCAT对动脉粥样硬化的影响,LCAT缺乏症的临床特征,以及LCAT对人类研究中心血管疾病的影响。虽然LCAT的生物化学及其对HDL代谢的影响已取得了很大进展,但其在动脉粥样硬化发病机制中的作用仍不完全清楚。来自各种动物模型的研究揭示了LCAT和动脉粥样硬化之间复杂的相互作用,其可以通过饮食和其他修饰脂蛋白的蛋白质来修饰。此外,LCAT降低apoB的能力似乎是预测其在动物模型中对动脉粥样硬化作用的最佳方式。最近对LCAT缺乏症患者的研究表明,心血管疾病的发病率适度但显著增加,这与LCAT对动脉粥样硬化的有益作用一致。然而,LCAT在一般人群中的作用并未显示与心血管疾病的一致关联。动物和人类研究的最新研究结果揭示了LCAT在减少动脉粥样硬化方面的潜在有益作用,但需要进行更多的研究以更好地建立LCAT与心血管疾病之间的联系。
We discuss the latest findings on the biochemistry of lecithin:cholesterol acyltransferase (LCAT), the effect of LCAT on atherosclerosis, clinical features of LCAT deficiency, and the impact of LCAT on cardiovascular disease from human studies. Although there has been much recent progress in the biochemistry of LCAT and its effect on HDL metabolism, its role in the pathogenesis of atherosclerosis is still not fully understood. Studies from various animal models have revealed a complex interaction between LCAT and atherosclerosis that may be modified by diet and by other proteins that modify lipoproteins. Furthermore, the ability of LCAT to lower apoB appears to be the best way to predict its effect on atherosclerosis in animal models. Recent studies on patients with LCAT deficiency have shown a modest but significant increase incidence of cardiovascular disease consistent with a beneficial effect of LCAT on atherosclerosis. The role of LCAT in the general population, however, have not revealed a consistent association with cardiovascular disease. Recent research findings from animal and humans studies have revealed a potential beneficial role of LCAT in reducing atherosclerosis but additional studies are necessary to better establish the linkage between LCAT and cardiovascular disease.
