摘要
白细胞介素-2(interleukin-2,IL-2)在T淋巴细胞及其它免疫细胞活化、分化和增殖等过程中起着非常重要的作用,我们通过观察肝硬化患者外周血淋巴细胞(peripheralbloodlym-phocytes,PBL)IL-2mRNA的表达,以及IL-2分泌水平的改变,探讨肝硬化患者淋巴细胞IL-2分泌不足的机理。实验结果显示,肝硬化患者IL-2mRNA表达较正常对照明显减弱,表达细胞数未见明显变化;PBL转化后IL-2mRNA表达增强,但肝硬化患者较对照仍有明显差异,IL-2分泌在肝硬化患者明显低于正常对照;淋巴细胞活化后,肝硬化患者与对照无明显差异。结果表明,许多有害因素通过降低外周血淋巴细胞IL-2mRNA的表达,影响IL-2产生、分泌,导致肝硬化患者免疫功能降低。
