摘要

As mitochondria have crucial roles in metabolism and signaling, their structure and function must be continuously monitored and rapidly adjusted to meet cellular demands. Critical to this regulation is a conserved stress response that detects and alleviates challenges to mitochondrial integrity. Recent work has shown that mitochondrial stress often elicits simultaneous protective reactions that act in a coordinated and tightly regulated fashion to preserve this essential organelle. Here we review components, coordination and control within this comprehensive stress response and discuss how increased understanding of mitochondrial stress signaling is beginning to inform therapeutic approaches directed against diseases of high unmet need.
