Research brief

Bacterial enterobactin and worm behaviour, lifespan: abstract only

In an abstract, a screen of E. coli gene-deletion mutants in C. elegans linked bacterial iron genes and enterobactin to worm movement, lifespan and healthspan via host mitochondria. [1]

Automatic summary · not editorially reviewed

The key findings

  1. The screen combined 3,985 E. coli single-gene deletion mutants with C. elegans and profiled 768 behavioural features per clone. [1]

  2. Loss of enterobactin biosynthesis abolished the bacteria-induced changes in worm movement. [1]

  3. Enterobactin-binding targets included mitochondrial glutaryl-CoA dehydrogenase and electron-transfer flavoproteins A and B. [1]

E. coli mutants screened in C. elegans

The authors built a screening platform to test how bacterial genes shape behaviour. They used the E. coli Keio library of 3,985 non-essential single-gene deletion mutants together with the worm C. elegans, and profiled 768 behavioural features per bacterial clone. This identified a group of bacterial genes involved in iron homeostasis that changed host behaviour.

Enterobactin and worm movement in the abstract

Bacterial analyses showed that altered iron homeostasis increased siderophore production in a TCA-cycle-dependent way. Loss of enterobactin biosynthesis abolished the bacteria-induced changes in worm movement. Further studies indicated that bacterial enterobactin activates host neuromuscular responses and shapes lifespan and healthspan depending on the mitochondrial unfolded protein response.

Binding targets and redox pathway in the abstract

Thermal proteome profiling identified mitochondrial glutaryl-CoA dehydrogenase and electron-transfer flavoproteins A and B as enterobactin-binding targets that control mitochondrial function. Genetic manipulation of neuronal mitochondrial and cytosolic reactive oxygen species via superoxide dismutase and catalase showed that redox state modulates enterobactin-driven changes in movement and lifespan through the neuropeptide receptor PDFR-1. The authors describe enterobactin as a non-canonical neurotransmitter.

How to interpret this

Abstract only; the full text was not reviewed. Findings come from E. coli and C. elegans experiments and do not establish human lifespan or health benefits.

Based on the study abstract; the full paper, tables and supplementary data were not reviewed.
