IRF2向IRF1的转录控制转换驱动先天免疫细胞激活
Switching of transcriptional control from interferon regulatory factor 2 to interferon regulatory factor 1 drives innate immune cell activation
导读
Toll样受体信号通路通过触发干扰素刺激基因启动子和增强子处IRF2向IRF1占据的转换,在无干扰素情况下激活促炎性干扰素刺激基因。新翻译的IRF1通过招募E3泛素连接酶SPOP促进较弱的转录激活因子IRF2的蛋白酶体降解。
推荐理由
研究揭示了IRF1通过招募E3泛素连接酶SPOP降解IRF2的机制,为理解干扰素非依赖的先天免疫激活提供了新视角。
