Unique metabolic profiles of Blautia wexlerae achieve beneficial effects for the control of obesity and type 2 diabetes
Bibliographic record
Abstract
Abstract The gut microbiome is an important determinant in various diseases. Here we performed a cross-sectional study of Japanese adults and identified the Blautia genus, especially B. wexlerae, as a commensal bacterium that is inversely correlated with obesity and type 2 diabetes mellitus. Oral administration of B. wexlerae to mice induced metabolic changes and anti-inflammatory effects that decreased both high-fat diet–induced obesity and diabetes. The beneficial effects of B. wexlerae were mediated directly by unique amino-acid metabolism to produce S-adenosylmethionine, acetylcholine, and l-ornithine and indirectly by carbohydrate metabolism resulting in the accumulation of amylopectin and production of succinate, lactate, and acetate and simultaneous modification of the gut bacterial composition. These findings reveal unique regulatory pathways of host and microbial metabolism that may provide novel strategies in preventive and therapeutic approaches for metabolic disorders.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
