1327-胰岛细胞移植中的免疫耐受与免疫逃逸

from 聊聊Sci

这篇文章对比了胰岛移植中移植耐受与免疫逃逸两种不同的免疫学策略。移植耐受侧重于调节受体的免疫系统,通过中枢性的胸腺筛选或外周性的淋巴器官干预,诱导机体对移植物产生特异性不反应。相比之下,免疫逃逸则是一种以移植物为中心的方法,通过基因工程手段使细胞获得“隐身”能力,从而躲避受体的免疫攻击。文中详细探讨了混合嵌合体、共刺激分子阻断以及调节性T细胞输注等前沿临床尝试,并分析了这些疗法在解决1型糖尿病患者长期免疫抑制负担方面的潜力与挑战。最终,研究旨在开发出无需持续药物治疗即可实现移植物长期存活的细胞替代疗法。References:Deuse T, Schrepfer S.
