人PON 1是一种HDL相关的脂内酯酶,能够防止LDL和细胞膜氧化,因此被认为具有动脉粥样硬化保护作用。P0 N1有助于HDL的抗氧化功能,并且HDL-P0 N1活性的降低(在具有炎症组分的多种疾病中普遍存在)被认为导致可促进炎症和动脉粥样硬化的功能失调的HDL。然而,PON 1是多功能的,可能有助于其他HDL功能,如先天免疫,通过破坏群体感应的酰基内酯介体来防止群体感应革兰氏阴性菌感染,以及在癌症发展和促进健康老龄化中的推定新作用。在这篇综述中,我们探讨了PON 1在疾病发展中的生理作用,以及PON 1基因和蛋白质结构,混杂活动和SNPs和种族在决定PON 1活性中的作用。
Human PON1 is a HDL-associated lipolactonase capable of preventing LDL and cell membrane oxidation and is therefore considered to be atheroprotective. PON1 contributes to the antioxidative function of HDL and reductions in HDL-PON1 activity, prevalent in a wide variety of diseases with an inflammatory component, is believed to lead to dysfunctional HDL which can promote inflammation and atherosclerosis. However, PON1 is multifunctional and may contribute to other HDL functions such as in innate immunity, preventing infection by quorum sensing gram negative bacteria by destroying acyl lactone mediators of quorum sensing, and putative new roles in cancer development and the promotion of healthy ageing. In this review we explore the physiological roles of PON1 in disease development, as well as PON1 gene and protein structure, promiscuous activities and the roles of SNPs and ethnicity in determining PON1 activity.
