Assessment in Mice of the Therapeutic Potential of Tailored, Multivalent Shiga Toxin Carbohydrate Ligands
Bibliographic record
Abstract
The therapeutic potential of 2 soluble multivalent receptor-based inhibitors of Shiga toxin (Stx) 1 and Stx2 was determined in mice. One of these, Starfish, protected mice when it was injected subcutaneously in admixture with a lethal dose of Stx1 but not Stx2. Starfish also reduced the distribution of (125)I-Stx1 but not (125)I-Stx2 to the murine kidney and brain. A modified version of Starfish, called "Daisy," in which the Stx alpha Gal(1,4)beta Gal(1,4)beta Glc receptors were installed on the core glucose structure via a modified tethering strategy, protected mice against both Stx1 and Stx2. Daisy also protected streptomycin-treated mice from Escherichia coli O91:H21 and did not interfere with the ability of the murine immune system to produce Stx-specific protective antibodies. These results extend the possibility of using soluble carbohydrate-based receptor inhibitors to prevent Stx-mediated complications arising from infections with enterohemorrhagic E. coli serotypes.

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.
