Mitochondrial translation, dynamics, and lysosomes combine to extend lifespan.

ABSTRACT

In this issue, Liu et al. (2019. J. Cell. Biol.https//doi.org/10.1083/jcb.201907067) find that the inhibition of mitochondrial ribosomes in combination with impaired mitochondrial fission or fusion increases C. elegans lifespan by activating the transcription factor HLH-30, which promotes lysosomal biogenesis.
