摘要: 他克莫司(Tacrolimus, FK506)是目前国内外器官移植术后的首选抗排斥反应药物,它通过抑制钙调神经磷酸酶而发挥免疫抑制作用。移植术后糖尿病(Post-transplantation diabetes mellitus, PTDM)是器官移植后的一种常见的并发症,发病率为2%~53%。PTDM与FK506抑制钙调神经磷酸酶关系密切。FK506使钙调神经磷酸酶活性受到抑制,阻碍细胞浆中的T细胞活化核因子(NFATc)去磷酸化,使NFATc不能核转位,抑制其与靶DNA结合,导致启动子不能启动相关基因的转录,一方面影响β细胞的增殖、细胞凋亡以及胰岛素的分泌,使胰岛素水平降低,另一方面使胰岛素的靶组织对胰岛素的敏感性和反应性降低,从而导致PTDM的发生。

Abstract: Tacrolimus (FK506), a calcineurin phosphatase inhibitor, is the base anti-rejection drug after organ transplantation. Post-transplant diabetes mellitus (PTDM) is a complication after a solid organ transplant, and its incidence is widely variable, ranging from 2% to 53%. Tacrolimus is an important risk of PTDM. Tacrolimus inhibits the dephosphorylation of the nuclear factor of activated T-cells (NFATc) in cytoplasm by inhibiting the function of the calcineurin. Then the transport of NFATc into the nucleus and combination with the target DNA are impaired. As a consequence, the promoter cannot activate the transcription of related genes, which decrease the level of insulin by affecting beta cell proliferation, apoptosis and the secretion of insulin and increase the insulin resistance in the target tissue of insulin, leading to the development of PTDM.

Key words: Tacrolimus, Diabetes, Calcineurin/NFATc signaling
