摘要 目的:研究IL-16对人白血病细胞系MT2细胞增殖抑制和凋亡的影响,为进一步研究IL-16功能奠定基础。方法:IL-16腺病毒载体转染MT2细胞后,不同时间收获细胞,通过MTT、流式细胞术(FCM)、测定线粒体膜电位和单细胞凝胶电泳等方法,证实MT2细胞增殖抑制和凋亡。结果:用MTT法绘制生长曲线,观察到IL-16腺病毒载体转染的MT2细胞增殖受到明显抑制;DNA片段分析在转染6h后出现凋亡片段;进一步用FCM检测细胞周期停滞于G1期,并且出现细胞凋亡;单细胞凝胶电泳发现细胞12h后有明显凋亡DNA拖尾形成;IL-16对细胞线粒体膜电位的影响24h内逐渐增强,预示细胞凋亡;免疫荧光发现12h自噬相关蛋白LC3,即可在细胞膜上表达,自噬已经开始出现。结论:重组人IL-16腺病毒载体转染MT2细胞,24h内即可诱导MT2细胞发生细胞增殖抑制并且出现凋亡,为进一步研究IL-16的功能奠定了基础。
