The FERM guild: a differentially correlated microbial module drives hypertension via metabolic flux perturbations.

A microbial module called the FERM guild influences hypertension through metabolic flux disruptions, involving 17 key metabolites linked to blood pressure regulation.

• Why it matters: Hypertension is a leading cause of cardiovascular disease, but individual differences in gut microbiota make it difficult to identify consistent pathogenic mechanisms; focusing on metabolites offers a more stable target.
• What they did: Using metabolic modeling, causal inference, and network analysis, the study identified 17 metabolites associated with hypertension and characterized the FERM guild, a microbial subnetwork of 19 species, whose metabolic contributions are linked to blood pressure.
• The result: Disruption of the FERM guild correlates with hypertension without changes in species abundance, highlighting microbial metabolic fluxes as promising targets for therapeutic intervention and advancing understanding of microbiome-host interactions.
