  • 产品描述:
        APOE是一种载脂蛋白,可以帮助调节胆固醇和三酰甘油等脂质分子在人体内的运输。APOE基因有三种主要的基因型,不同的基因型会影响人体对脂质代谢的调节能力。APOE还参与多种生理过程,如神经元的生长和修复、调节免疫反应等。
        APOE基因型与多种疾病的发生风险有关,尤其是与神经系统相关的疾病,如阿尔茨海默病、帕金森病和多发性硬化等。APOEε4基因型是阿尔茨海默病的一个重要风险因素,而APOEε2基因型则被认为与心血管疾病的发生风险降低有关。因此,APOE对疾病的预防和发生机制的研究具有重要意义。

  • 功能:
    APOE is an apolipoprotein, a protein associating with lipid particles, that mainly functions in lipoprotein-mediated lipid transport between organs via the plasma and interstitial fluids. APOE is a core component of plasma lipoproteins and is involved in their production, conversion and clearance. Apoliproteins are amphipathic molecules that interact both with lipids of the lipoprotein particle core and the aqueous environment of the plasma. As such, APOE associates with chylomicrons, chylomicron remnants, very low density lipoproteins (VLDL) and intermediate density lipoproteins (IDL) but shows a preferential binding to high-density lipoproteins (HDL). It also binds a wide range of cellular receptors including the LDL receptor/LDLR and the very low-density lipoprotein receptor/VLDLR that mediate the cellular uptake of the APOE-containing lipoprotein particles. Finally, APOE has also a heparin-binding activity and binds heparan-sulfate proteoglycans on the surface of cells, a property that supports the capture and the receptor-mediated uptake of APOE-containing lipoproteins by cells.
