1、徐州医学院硕士学位论文常山酮对小鼠急性肠道移植物抗宿主病的影响姓名:李护君申请学位级别:硕士专业:专业学位指导教师:徐开林;潘秀英2012-05徐州医学院硕士学位论文常山酮对小鼠急性肠道移植物抗宿主病的影响中文摘要目的通过观察小鼠急性移植物抗宿主病(acutegraft-versus-hostdisease,aGVHD)外周血Thl/Thl7细胞比例及小肠中的T-bet、RORTtmRNA表达变化,探讨常山酮对小鼠急性肠道GVHD中的影响。方法以C57BL/6小鼠为供鼠,BALB/c为受鼠,建立aGVHD模
2、型,并以常山酮抑伟i]Thl7细胞的发育。移植后观察受鼠生存状况,流式细胞术检测外周血及小肠组织中CD4+T细胞中,nll/Thl7细胞的比例,使用CBA法检OⅢIJlFN.Y和IL.17A的浓度,并以RT-PCI凇测小肠T-bet、RORvt、CXCL9~11及CCL20表达。同时使用小鼠aGVHD临床评分、外周血炎症细胞因子浓度检测和病理学评分评价小鼠发生aGVHD时全身炎症的严重程度和靶器官的损伤情况。结果移植后7d移植组出现典型GVHD表现,联合常山酮组较常规GVHD组加重。移植后7d和14天,联合
3、常山酮组Thl7细胞比例明显低于常规GVHD组(P4、常对照组明显升高。结论1.小鼠aGVHD发生过程中,常山酮加重系统性GVHD。2.肠道GVHD与Thl7细胞密切相关,抑制Thl7细胞加重肠道GVHD,提示Thl7细胞可能起保护作用。关键词急性移植物抗宿主病;CCL20:Thl7细胞’徐州医学院硕士学位论文Halofuginoneexacerbatemouseacuteintestinegraft--versus--hostdiseasefollowingallogeneticbonemarrowtransplantationAbstractObjecti5、veToexploretheroleofhalofuginoneinmouseacuteintestinegraft-versus—hostdiseaseafterallogeneticbonemarrowtransplantation.MethodsFemaleBALB&(H一2Kd)micewerelethallyirradiatedby叫Cosource,andthenwereinjectedintravenouslywithbonemarrowcellsfromC57BL/6(H.2Kb)mice.6、Themiceweredividedinto5groups:normalcontrol,irradiatedgroup,allo-BMT+SCgroup,allo-BMT+SC+DMSOgroup:DMSOwasgivenintraperitoneallyat0.3mlperfrom—ldto10dafteralogeneicbonemarrowtransplantation.mouse;Allo-BMT+SC+HFgroup,HFwasgivenintraperitoneallyat599perfrom—7、ldtolOdafteralogeneicbonemarrowtransplantation.mouse.MiceaGVHDwasassessedbyclinicalsigns,histopathologyat14d,andperipheralproinflammatorycytokinesandIFNqandIL.17Awereexaminedbycytometricbeadarray.Meanwhile,ThelevelsofThl/Thl7weremeasuredbyTri—colorflowcyto8、metry.AlsointestineT-bet,ROgrt,GATA.3,Foxp3,CXCL9,CXCL10,CXCLl1andCCL20mRNAlevelswerealsodetectedbyReal-timePCR.Therecipientsweremonitoreddailyforsurvivalandevery2daysforboayweightchange.Results1.Bothtranspla
