Abstract
AIMS: To evaluate the immunosuppressive properties of the exopolysaccharide (EPS) from high-EPS producer Lactobacillus rhamnosus RW-9595M on inflammatory cytokines produced by macrophages. METHODS AND RESULTS: The conditioned media (CM) were produced by macrophages treated with parental Lact. rhamnosus ATCC 9595 and its isogenic variant, the high-EPS producer Lact. rhamnosus RW-9595M, and the levels of TNF-alpha, IL-6, IL-10 and IL-12 were evaluated. Results revealed that CM from parental Lact. rhamnosus induced higher levels of TNF-alpha, IL-6 and IL-12 but inhibited IL-10 production, whereas its mucous variant induced low or no TNF-alpha and IL-6. Addition of purified EPS to macrophages treated with parental Lact. rhamnosus decreased the inflammatory cytokines and inhibited the metabolic activity of lymphocytes. The intermediate polysaccharide chains (16-30 units) produced by time-controlled hydrolysis of EPS increased the IL-10 produced by macrophages. CONCLUSIONS: Polysaccharide chains of EPS induced immunosuppression by the production of macrophagic anti-inflammatory IL-10. SIGNIFICANCE AND IMPACT OF THE STUDY: These results indicate that the EPS from Lact. rhamnosus RW-9595M may be useful as a new immunosuppressive product in dairy food.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
