- 脂解制备物酯酶活性的非变性蛋白电转移研究
- 酶法胆固醇测定试剂（含胆固醇氧化酶）的组分优化研究
- 修饰人血浆低密度脂蛋白(LDL)，用于在分支组织工程血管(TEBV)中诱导内皮细胞(EC)障碍和单核细胞黏附(MC)

该酶广泛应用于诊断实验室血清胆固醇的测定。
Biochem/physiol Actions
胆固醇酯酶(CE)是一种可水解或合成胆固醇等固醇物质脂肪酸酯部分的可逆性酶。胆固醇酯酶活性在类固醇生物合成或类固醇从头合成(de novo steroidogenesis)中起重要作用。对水不溶性长链脂肪酸酯的水解需要胆汁盐激活。对水溶性短链脂肪酸酯和溶血磷脂的水解则不需要胆汁盐激活。还可水解甘油三酯、甘油二酯和甘油一酯、磷脂、溶血磷脂和神经酰胺。该酶在脂质和脂蛋白代谢以及动脉粥样硬化中起多种作用。
General description
研究领域：细胞信号转导
胆固醇酯酶(CE)是一种糖蛋白，可从柱状假丝酵母和荧光假单胞菌等真菌中提取。属于脂肪酶/酯酶家族成员，以同型二聚体形式发挥作用。胆固醇酯酶在胰腺中生成，经胆囊收缩素(CCK)刺激后以活性形式释放。

Atherosclerosis begins with the accumulation of cholesterol-carrying lipoproteins on blood vessel walls and progresses to endothelial cell dysfunction, monocyte adhesion, and foam cell formation. Endothelialized tissue-engineered blood vessels (TEBVs) have previously been fabricated to recapitulate artery functionalities, including vasoconstriction, vasodilation
