2、al.tiInePCR、免疫组化和趋化实验重点分析了肝癌组织内趋化因子的水平及对调节性T细胞的趋化性。此外,通过对CD3、CD4、CD8和FoxP3表达的免疫组化检测及生存分析,探讨了肿瘤浸润淋巴细胞与肝癌肝移植患者预后的相关性。II浙江大学博士学位论文摘要研究结果肝癌组织内有调节性T细胞无论是比例还是绝对数量都较非癌或正常肝组织显著增加(P3、验证实:外周血中的调节性T细胞能向趋化因子CcL20选择性的迁移。肝癌组织中调节性T细胞在CD41细胞中的比例与肝癌肝移植患者的生存相关,为一个独立性危险因素。此外,通过受试者特征曲线(玎eceiveroperatiIlgcharacteristiccllrve,ROc)分析发现:调节性与细胞毒性T细胞组合分析的曲线下面积(areauIldercuⅣe,AUC)显著大于调节性T细胞单个因素分析(尸4、调节性与细胞毒性T细胞组合分析能提高对肝癌患者预后判断的准确性。关键词:肝细胞肝癌、调节性T细胞、趋化因子、趋化因子受体、迁移、预后Ⅱl塑垩奎兰堕主学竺论文摘要TheroleofregulatoryTcellsillthedeVelopmentofObjectiVes:hepatoCeUularCarcinomaZhejiangUniVersitySch00lofMedicineDoctoratecandjdateChenKang-JieTutorProf.ZhengShu-SenAbstract1.Toexplorememechallismbywhichregulato巧Tc5、ellsofp嘶phe脚b100dmi铲ate访totumortissueiIlh印atocellularcarcinomapatients.2·TbiIlVestigatctlle嬲sociationoft啪or.i11filtratinglynlphocytes,especiallyregulatoryTcells,wimprognosisofhepatocellularcaI℃iIlomapatiems.Methods:T敞ingperipheralblooda11dtuIIlortissueofpatientsassubject,wedetectedmedensity’6、distribution,phenotype锄dfunctionoftunlor-deriVedregulatoryTcellsbynowc”ometIMi姗uIlohistochemicalstaining,immunosuppressiveassay;weiIlVest追atedtlleleVelofselectiVechemokinesiIlliVertumortissuebyreal—timePCR柚di删mlmohistochemicalstainin舀弱wellaschemotaXisofregulatorytotlleseTV浙江大学博士学位论文摘要chemoki7、Ilesinvitro.Besides,weevaluatedtlleassociationoftumor-i11filtratinglymphocyteswimprognosisofhepatocellularcarcmomapatientsbydetectingtlleexpressionofCD3,CD4,CD8andFoxP3usingir眦unohistochemicalStaining,觚(1aIlalyzingusingKaplaIl—Meiera11dCoxregressio
