Reports that an antimicrobial compound remodels macrophage mitochondrial quality control and that the same mechanism extended lifespan in nematode worms.

K21 Improves Mitochondrial Function in Macrophages, Extending Life in Nematode Worms
Key Takeaways
  • K21 exposure increased mitochondrial fission and DRP-1–mediated mitophagy in macrophages and in vivo in C.
  • K21 improved mitochondrial function without reducing viability, development, or fertility in treated nematodes.
  • Delivery of K21 to nematodes produced a measurable extension of lifespan consistent with improved mitochondrial health.
