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

A microbial module called the FERM guild is linked to hypertension through metabolic flux perturbations involving 17 key metabolites.

• Why it matters: Understanding the mechanisms behind hypertension is crucial due to its status as a major global health burden, and traditional species-abundance analyses are limited by high individual variability.
• What they did: The study used metabolic modeling, causal inference, and network analysis to identify 17 metabolites associated with blood pressure and a microbial subnetwork of 19 species, including Faecalibacterium and Roseburia, whose contribution to metabolites correlates with blood pressure.
• The result: Findings suggest that hypertension is associated with disruptions in gut microbial diversity, structure, and metabolic function, highlighting microbial metabolites and the FERM guild as promising targets for therapeutic intervention.
