一、中文名称:Anti-Mouse CD71/TFRC Antibody (OX-26)(FMC02020),鼠CD71/转铁蛋白受体1抗体
二、产品描述
CD71,全称转铁蛋白受体1(Transferrin Receptor 1,TfR1),别称包括TFRC、p90、sTfR等,是一种II型跨膜糖蛋白,由两个90 kDa的亚基通过二硫键形成同源二聚体。CD71通过网格蛋白依赖的内吞作用介导铁离子摄取,维持细胞内铁稳态,对增殖细胞(如造血细胞、肿瘤细胞)和活化免疫细胞(如T细胞、B细胞前体、NK细胞)至关重要。在静息白细胞中表达较低,但在激活或增殖状态下显著上调。此外,CD71在胎盘组织、肌肉(心肌、腓肠肌)及未成熟红细胞中也高表达。功能上,CD71不仅调控铁代谢,还参与肿瘤进展,因其在多种实体瘤中高表达并与不良预后相关。其与转铁蛋白复合物的内吞过程被病原体(如都瓦病毒、疟原虫)利用以入侵细胞,结构研究表明其胞外域顶端为病原体结合的关键区域。CD71还作为抗体药物偶联物(ADC)的靶点,因肿瘤细胞表面异常高表达而成为治疗潜力。研究还发现,CD71表达与促炎因子(如IL-6、IFN-γ)及T细胞活性标志物(CD39、CD25)呈正相关,提示其在免疫调节中的作用。
