老年斑是阿尔茨海默病(Alzheimer's disease,AD)的病理标志。β淀粉样肽(Aβ)是老年斑的主要成分,具有神经毒性,尤其是寡聚体形式。Aβ来源于淀粉样蛋白生成途径中β-和γ-分泌酶对淀粉样前体蛋白(APP)的连续裂解。或者,APP可被Aβ结构域内的α-分泌酶裂解,在非淀粉样蛋白生成途径中产生神经营养性和神经保护性α-分泌酶裂解的可溶性APP(sAPPα)。由于APP和α-、β-和γ-分泌酶都是膜蛋白,APP加工应高度依赖于膜组成和细胞膜的生物物理性质。本文综述了细胞膜的生物物理性质在APP加工中的作用,特别是磷脂酶A2(PLA 2s)、脂肪酸、胆固醇和Aβ对APP加工中细胞膜流动性的影响。
The senile plaque is a pathologic hallmark of Alzheimer’s disease (AD). Amyloid-β peptide (Aβ), the main constituent of senile plaques, is neurotoxic especially in its oligomeric form. Aβ is derived from the sequential cleavage of amyloid precursor protein (APP) by β- and γ-secretases in the amyloidogenic pathway. Alternatively, APP can be cleaved by α-secretases within the Aβ domain to produce neurotrophic and neuroprotective α-secretase-cleaved soluble APP (sAPPα) in the nonamyloidogenic pathway. Since APP and α-, β-, and γ-secretases are membrane proteins, APP processing should be highly dependent on the membrane composition and the biophysical properties of cellular membrane. In this review, we discuss the role of the biophysical properties of cellular membrane in APP processing, especially the effects of phospholipases A2 (PLA2s), fatty acids, cholesterol, and Aβ on membrane fluidity in relation to their effects on APP processing.
