Sickle cell disease (SCD) is caused by a point mutation in the β-globin gene that creates hemoglobin S (HbS). Upon deoxygenation, HbS forms long polymers that distort the shape of red blood cells, causing hemolysis and vaso-occlusion. Voxelotor inhibits HbS polymerization, the root cause of SCD complications. To view this Bench to Bedside, open or download the PDF.
镰状细胞病(SCD)是由β-珠蛋白基因中的一个点突变引起的,该突变导致血红蛋白 S(HbS)的形成。当脱氧时,HBs 形成长聚合物,使红细胞形状发生扭曲,导致溶血和血管阻塞。Voxelotor 可抑制 HbS 聚合,这是 SCD 并发症的根本原因。要查看此从实验室到临床的转化,请打开或下载 PDF。
