摘要

雷帕霉素哺乳动物靶标(mTOR,又称雷帕霉素机制靶标)是一种保守的丝氨酸-苏氨酸激酶,并形成两个大型蛋白复合物(mTOR 复合物 1 和 2(mTORC1 和 mTORC2))。mTORC2的功能尚不十分清楚,但mTORC1作为细胞内的中心代谢调节器已广为人知。mTORC1整合并协调细胞对来自细胞内和细胞外能量水平信号的反应。在2017年发表的一篇论文中,布兰迪诺-罗萨诺及其同事利用小鼠有条件和诱导性地缺失β细胞中的Raptor(编码mTORC1调控相关蛋白的基因)(β细胞调控胰岛素的产生和分泌,因此对维持葡萄糖稳态至关重要)。这项研究证实,由于β细胞增殖、凋亡、自噬和胰岛素分泌的缺陷,缺乏mTORC1会导致高血糖和低胰岛素血症。
