Comamonas aquatica significantly protects Caenorhabditis elegans motor neurons from degeneration triggered by TIR-1/SARM1 overexpression.
- Why it matters: The microbiome’s neuroprotective members and their host molecular mechanisms are unclear, limiting understanding of gut-brain interactions in neurodegenerative processes.
- What they did: Using C. elegans fed single-species diets, the study combined genetic tests with metabolomics to show vitamin B12 from Comamonas aquatica activates METR-1/MTR methionine synthase in the intestine.
- The result: Vitamin B12–dependent METR-1/MTR activity lowers toxic homocysteine levels in TIR-1-expressing animals, defining a pathway linking Comamonas aquatica to reduced axon degeneration.
