Carbohydrate sulfation as a critical modulator of siglec-sialoglycan interactions
Bibliographic record
Abstract
Siglecs are sialic acid-binding immunomodulatory receptors that regulate immune homeostasis. Abnormal alterations in sialic acid-containing glycans (sialoglycans) on tissues or cells are key drivers of various diseases, including cancer, neurodegenerative disorders, allergies, and autoimmune diseases. Consequently, the role of Siglecs as immune checkpoints has gained increasing attention. To better understand Siglec biology, comprehensive approaches have been employed to elucidate Siglec ligands, including chemical synthesis for glycan microarrays and genetic manipulation of glycosyltransferases for understanding their biosynthesis process. These efforts have revealed that carbohydrate sulfation, catalyzed by carbohydrate sulfotransferases (CHSTs), fine-tunes Siglec-sialoglycan interactions by enhancing binding affinities. This review summarizes the latest insights into sulfated sialoglycan ligands for individual Siglecs.

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.
