卵磷脂胆固醇酰基转移酶(lecithin cholesterol acyl transferase,LCAT)酯化游离胆固醇,是血浆高密度脂蛋白生成 和成熟的关键酶,可能也在胆固醇逆转运中起重要作用,一直推测 LCAT 是重要动脉粥样硬化保护因素,但有关实验室、动物 和人群研究结果多有矛盾.LCAT 与动脉粥样硬化的关系高度复杂,研究结果不一的一种可能原因是研究方法或对象不同.对于人群研究,体内 LCAT 活性影响因素众多,目前测定方法多变,所得结果可能反映不同生物学意义,也缺乏评价 LCAT 体 内活性的有效指标,因而导致研究结果不一.建立合适的 LCAT 活性测定方法,研究其影响因素,可能对阐明 LCAT 与动脉粥 样硬化的关系及心血管病危险分析具有重要意义.
Lecithin cholesterol acyl transferase (LCAT ) esterifies free cholesterol and is a key enzyme in the formation of plas - ma high density lipoproteins. It may also crucial in macrophage reverse cholesterol transfer . It has long been believed that LCAT activity is atheroprotective, but studies on the effect of LCAT on atherosclerosis are still highly controversial . Part of the controversy may be ex - plained by the difference in study design ,but the role of LCAT in atherogenesis is far from being fully understood . For population -based studies, the current methods for the measurement of LCAT activities are highly variable and may have different biological meanings . Reliable measurement of LCAT that effectively reflects the in vivo activities is needed for elucidating the relation between LCAT and ather - osclerosis and for the risk analysis of cardiovascular diseases .
