中文摘要:

T 帮助房间 17 (Th17 ) ,最近作为 CD4+ T 房间的一个新子集识别了,在自体免疫的疾病被含有,肿瘤免疫,并且移植拒绝。在尖锐肝的拒绝调查 Th17 的角色, allogeneic 肝移植(到布朗挪威(BN ) 的黑暗刺鼠(DA )) 的一个老鼠模型被建立, isogeneic 肝移植(到 BN 的 BN ) 在学习被用作控制。在肝和外部血的 Th17 相关的 cytokines 的表示被 immunohistochemistry,流动 cytometry,连接酶的 immunosorbent 试金(ELISA ) ,或即时量的反向的抄写聚合酶链决定反应(RT-qPCR ) 。interleukin-17A (IL-17A ) 的强壮的表示, IL-6,转变生长因素 --(TGF-) , IL-8,和 myeloperoxidase (军邮局) 在肝 allografts 被观察。到在肝和外部血的 CD4+ 淋巴细胞的 Th17 的比率戏剧性地与控制相比在 allograft 组被增加(P < 0.01 ) 。在肝 homogenate 和浆液的分泌 IL-17 和 IL-6 显著地在 allograft 组被提高,当分泌 TGF- 在肝 homogenate 被增加并且与控制相比在浆液减少了时(P < 0.01 ) 。IL-17, IL-21,和 IL-23 的送信人 RNA (mRNA ) 层次与控制相比在 allografts 被提高(P < 0.01 ) 。关联分析显示出在 IL-17 和 IL-6 和 TGF- 之间并且在 IL-17 和 IL-21 和 IL-23 之间的重要关联。现在的学习证明 Th17 在支持老鼠肝 allograft 拒绝起一个作用。

英文摘要:

T help cell 17(Th17) ,recently identified as a new subset of CD4+T cells,has been implicated in autoimmune diseases,tumor immunity,and transplant rejection.To investigate the role of Th17 in acute hepatic rejection,a rat model of allogeneic liver transplantation(Dark Agouti(DA) to Brown Norway(BN) ) was established and isogeneic liver transplantation(BN to BN) was used as controls in the study.The expression of Th17-related cytokines in the liver and peripheral blood was determined by immunohistochemistry,flow cytometry,enzyme-linked immunosorbent assay(ELISA) ,or real-time quantitative reverse transcription polymerase chain reaction(RT-qPCR) .Strong expression of interleukin-17A(IL-17A) ,IL-6,transforming growth factor-β(TGF-β) ,IL-8,and myeloperoxidase(MPO) was observed in liver allografts.The ratios of Th17 to CD4 + lymphocytes in the liver and peripheral blood were dramatically increased in the allograft group compared with the control(P〈0.01) .Secreted IL-17 and IL-6 in liver homogenate and serum were significantly elevated in the allograft group,while secreted TGF-βwas increased in liver homogenate and decreased in serum compared with the control(P〈0.01) .The messenger RNA(mRNA) levels of IL-17,IL-21,and IL-23 were enhanced in the allografts compared with the control(P〈0.01) .Correlation analysis showed significant correlations between IL-17 and IL-6 and TGF-βand between IL-17 and IL-21 and IL-23.The present study demonstrates that Th17 plays a role in promoting rat liver allograft rejection.
