在这里,我们提出了一个协议,以诱导和评分疾病在异种移植-宿主疾病(xenoGVHD)模型。xenoGVHD为研究人类T细胞的免疫抑制提供了一个体内模型。此外,我们介绍如何使用数字PCR检测组织中的人类T细胞,作为量化免疫抑制的工具。
该协议概述了如何诱导异种移植与宿主疾病,或异种GVHD,以及如何盲目和标准化临床评分,以确保一致的结果。XenoGVHD模型提供了一种体内方法,用于测试针对人类而非穆林T细胞的免疫抑制疗法,从而改进了这些研究的转化过程。演示这个程序的将是阿马拉·森,一个研究生,从我的实验室。
注射前一天,将8至12周大、非肥胖的糖尿病scid伽玛(NSG)小鼠放在灭菌馅饼笼中,并在一个分量为150百分源的铀-137源中照射小鼠,并缓慢旋转以确保均匀的辐照。然后,将老鼠放入无菌生物安全柜中过夜的清洁笼中。第二天早上,收集足够的健康人类血液,每只小鼠分离1.1倍至7个外周血单核细胞(PBMC),并在PBS中以2%的相同体积稀释肝素化血液,即FBS。
