Effects of ovalbumin glycoconjugates on alleviation of orally induced egg allergy in mice via dendritic‐cell maturation and T‐cell activation
Bibliographic record
Abstract
SCOPE: Glycation of allergens via Maillard reaction or chemical conjugation has been shown to influence susceptibility to food-induced allergies. It is hypothesized that mucosal immune response bias can be favorably altered by orally administering various forms of glycated ovalbumin (OVA). METHODS AND RESULTS: Groups of Balb/c mice (n = 10) were orally sensitized to OVA and administered various forms of glycated OVA (glucose, mannose, glucomannan, galactomannan, and a mixture containing OVA and glucomannan). Outcomes post oral challenge were measured as clinical allergic signs, serum histamine, mouse mast cell protease 1 (MMCP-1), antibody activity, type-1/2 cytokines, percentage of T-regulatory cells (T-regs) and in vitro dendritic cell, and T-cell-related mechanisms. Clinical signs and specific IgE were decreased (p ≤ 0.05), and T-reg cell percentage was increased in the mannose and glucomannan treated groups. The OVA-mannose group also had less histamine, MMCP-1, specific IgG, IL-4 and IL-17, and more IL-12p70 (p ≤ 0.05). Other parameters measured did not differ significantly among groups. Also, OVA-glycated mannose reduced maturation and uptake by dendritic cells. Less activation of T cells and type-2 cytokine response in DC-T-cell cocultures were observed with OVA-glycated mannose stimulation. CONCLUSION: This study validates, for the first time, the use of OVA-glycated mannose and glucomannan for potential beneficial dietary interventions for allergy.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
