由T细胞受体(TCR)和共刺激分子介导的信号传导引发的免疫应答在最大细胞因子mRNA产生和稳定性中达到高潮。对共刺激T细胞信号传导的转录应答涉及钙调磷酸酶和NF-AT,其可以通过干扰顺式-反式肽基脯氨酰异构酶(PPI酶)、亲环素A和FKBP来拮抗。对于细胞因子mRNA的稳定至关重要的CD 28下游的信号分子在很大程度上是未知的。我们现在表明,Pin 1,PPIase家族的第三个成员介导的Th 1细胞因子的转录后调节激活的T细胞。通过药理学或遗传学手段阻断Pin 1极大地减弱了细胞活化后IFN-γ、IL-2和CXCL-10 mRNA的稳定性、积累和蛋白表达。在体内,Pin 1阻断通过降低IFN-γ和CXCL-10的表达来防止MHC不匹配的原位大鼠肺移植的急性和慢性排斥反应。环孢菌素A和Pin 1抑制剂胡桃醌联合转录和转录后阻断具有协同作用。这些数据表明,Pin 1抑制剂应探索用作免疫抑制剂,并与可用的钙调磷酸酶抑制剂一起使用,以降低毒性并提高有效性。
Immune responses initiated by T cell receptor (TCR) and costimulatory molecule mediated signaling culminate in maximal cytokine mRNA production and stability. The transcriptional responses to co-stimulatory T cell signalling involve calcineurin and NF-AT, which can be antagonized by interference with the cis-trans peptidyl-prolyl isomerases (PPIase), cyclophilin A and FKBP. Signalling molecules downstream of CD28 which are essential for the stabilization of cytokine mRNAs are largely unknown. We now show that Pin1, a third member of the PPIase family mediates the post-transcriptional regulation of Th1 cytokines by activated T cells. Blockade of Pin1 by pharmacologic or genetic means greatly attenuated IFN-γ, IL-2 and CXCL-10 mRNA stability, accumulation and protein expression after cell activation. In vivo, Pin1 blockade prevented both the acute and chronic rejection of MHC mismatched, orthotopic rat lung transplants by reducing the expression of IFN-γ and CXCL-10. Combined transcriptional and post-transcriptional blockade with cyclosporine A and the Pin1 inhibitor, juglone, was synergistic. These data suggest Pin1 inhibitors should be explored for use as immunosuppressants and employed with available calcineurin inhibitors to reduce toxicity and enhance effectiveness.
