Research Grade Belatacept,重组蛋白

发表时间:2025-02-26


一、中文名称:

Research Grade Belatacept,科研级Belatacept

二、产品描述

Belatacept 是一种重组融合蛋白,由细胞毒性 T 淋巴细胞相关抗原 4CTLA-4)的胞外结构域与人 IgG1 Fc 段融合而成,通过哺乳动物细胞表达系统生产。它在 T 淋巴细胞表面有较高亲和结合位点,当机体免疫系统启动,尤其是在器官移植等免疫反应强烈的场景下,Belatacept 能够快速结合抗原呈递细胞表面的 CD80 CD86,阻断它们与 T 淋巴细胞表面 CD28 的相互作用,抑制 T 淋巴细胞的过度活化,避免免疫排斥反应过度发生。临床前研究和器官移植实验表明,Belatacept 能有效降低移植排斥反应,在肾移植模型中,它减少了免疫细胞对移植肾的攻击,提高了移植肾的存活率和功能,对器官移植免疫研究及抗排斥药物研发意义重大。
