线粒体是重要的细胞器,在各种细胞信号传导和代谢途径中发挥核心作用。健康的线粒体群体通过一系列质量控制途径来维持,并且需要线粒体生物发生和降解之间的微调平衡。通过线粒体自噬将功能障碍的线粒体靶向到溶酶体的缺陷与几种疾病有关,但体内不同线粒体自噬途径的潜在机制和相对重要性在很大程度上是未知的。在这个细胞科学一瞥和随附的海报中,我们描述了我们目前对线粒体的部分或全部如何被自噬机制识别并靶向溶酶体降解的理解。我们还讨论了如何在不同的生理条件下调节这一点,以维持线粒体和细胞的健康。总结:这个细胞科学一瞥提供了关于线粒体如何被识别并靶向溶酶体在不同生理条件下降解以维持细胞稳态的见解。
Mitochondria are crucial organelles that play a central role in various cell signaling and metabolic pathways. A healthy mitochondrial population is maintained through a series of quality control pathways and requires a fine-tuned balance between mitochondrial biogenesis and degradation. Defective targeting of dysfunctional mitochondria to lysosomes through mitophagy has been linked to several diseases, but the underlying mechanisms and the relative importance of distinct mitophagy pathways in vivo are largely unknown. In this Cell Science at a Glance and the accompanying poster, we describe our current understanding of how parts of, or whole, mitochondria are recognized by the autophagic machinery and targeted to lysosomes for degradation. We also discuss how this might be regulated under different physiological conditions to maintain mitochondrial and cellular health. Summary: This Cell Science at a Glance provides insights into how mitochondria are recognized and targeted to lysosomes for degradation under different physiological conditions to maintain cellular homeostasis.
