发现LGP2通过结合dsRNA末端并内部易位启动MDA5丝状结构形成,使MDA5能够识别短病毒RNA;异质丝状微簇群可高效激活MAVS信号通路,扩展先天免疫检测范围。

📝 英文原版摘要

Kurihara et al. reveal that LGP2 binds dsRNA ends and translocates internally to nucleate MDA5 filaments. This mechanism allows MDA5 to recognize immunologically elusive short viral RNAs. The resulting heterofilament microclusters robustly trigger MAVS signaling, broadening the scope of innate immune detection.
