Cellular and organismal aging have been consistently associated with mitochondrial dysfunction and inflammation. Accumulating evidence indicates that aging-related inflammatory responses are mechanistically linked to compromised mitochondrial integrity coupled with mtDNA-driven CGAS activation, a process that is tonically inhibited by mitophagy.
细胞和机体衰老一直与线粒体功能障碍和炎症有关。越来越多的证据表明,与衰老相关的炎症反应在机制上与受损的线粒体完整性以及 mtDNA 驱动的 CGAS 激活有关,这一过程受到自噬的紧张抑制。
