研究背景:牙龈间充质干细胞(GMSCs)被认为可以用来治疗多种自身免疫性疾病,包括免疫性结肠炎,自身免疫性关节炎等.然而还尚无GMSCs是能够治疗急性移植物抗宿主病的研究报道.研究目的:我们通过研究GMSCs在急性移植物抗宿主病模型中的作用,鉴别GMSCs保护aGVHD的保护作用,并探究其保护机制与原理.方法:我们运用GMSCs治疗两种不同的小鼠急性移植物抗宿主病模型,通过流式检测监测供者,受者来源的T,B细胞数量变化情况以及细胞因子的变化情况.体外实验中,将GMSCs与na(i)ve T细胞在IL-2和TGF-β的环境下共培养,检测其Foxp3以及CD39的表达.在一些实验中抗CD39抗体被用来拮抗CD39+T细胞,观测拮抗CD39+T细胞后,GMSCs治疗移植物抗宿主病模型的生存率.最后,我们还监测了腺苷受体A1,A2A,A2B,A3在GMSCs保护aGVHD中的作用.
