在这里,我们提出的方法,纵向跟踪胰岛同种异体移植物浸润T细胞在活小鼠的内窥镜共聚焦显微镜和分析循环T细胞在体内流式细胞术。我们开发了一种新的报告小鼠,其T细胞亚群表达不同的“颜色编码”蛋白,能够在体内检测和鉴定效应T细胞(Teff细胞),并区分天然和诱导的调节性T细胞(nTreg和iTreg细胞)。使用这些工具,我们观察到接受耐受诱导治疗(CD154特异性单克隆抗体加雷帕霉素)的受者与未治疗的对照组相比,T细胞应答存在显著差异。这些结果建立了实时细胞跟踪作为一种强有力的手段来探测动态细胞相互作用介导的免疫排斥或移植耐受。
Here we present methods to longitudinally track islet allograft—infiltrating T cells in live mice by endoscopic confocal microscopy and to analyze circulating T cells by in vivo flow cytometry. We developed a new reporter mouse whose T cell subsets express distinct, ‘color-coded’ proteins enabling in vivo detection and identification of effector T cells (Teff cells) and discrimination between natural and induced regulatory T cells (nTreg and iTreg cells). Using these tools, we observed marked differences in the T cell response in recipients receiving tolerance-inducing therapy (CD154-specific monoclonal antibody plus rapamycin) compared to untreated controls. These results establish real-time cell tracking as a powerful means to probe the dynamic cellular interplay mediating immunologic rejection or transplant tolerance.
