由遗传性极高水平胆固醇引起心脏病发作的早期死亡危险人群有朝一日可以用猪肝细胞移植方法治疗。据美国研究人员称,猪细胞可以清除血液中大量形成凝块的脂肪。家族性高脂固醇血症是一种遗传性疾病,使病人不能够去除血液中低密度脂蛋白(LDL)型胆固醇。此病患者的肝细胞缺乏能正常清除血液中脂肪物质的受体。携带一个有缺陷LDL受体基因(杂合子)的病人血液中胆固醇水平是正常人的2～3倍。在2个LDL受体基因都有缺陷时,胆固醇水
People at risk of early death from a heart attack caused by hereditary high levels of cholesterol may one day be treated with porcine hepatocyte transplantation. According to U.S. researchers, pig cells can remove large amounts of clotted fat in the bloodstream. Familial hyperlipidemia is a hereditary disorder that prevents patients from removing low-density lipoprotein (LDL) cholesterol from the bloodstream. The patient’s liver cells lack the normal removal of blood fatty substances in the receptor. Patients with a defective LDL receptor gene (heterozygote) in the blood cholesterol levels two to three times normal. Cholesterol water is a flaw in both LDL receptor genes
