Generation and Characterization of Rat Anti-mouse ST2L Monoclonal Antibodies
Bibliographic record
Abstract
ST2L is a transmembrane receptor that belongs to the IL-1 receptor family. The receptor is expressed on various cell types including Th2 cells, mast cells, basophils, growth-activated fibroblasts, and vascular endothelial cells. ST2L activation by its ligand IL-33 has been implicated in Th2-mediated immunity, inflammation, and allergic responses in vivo. Inhibition of ST2L activity can attenuate Th2-dominated immune responses such as lung eosinophilia, airway hyper-responsiveness, and arthritis in animal models. Here we report the generation and in vitro characterization of a panel of rat anti-mouse ST2L monoclonal antibodies. We demonstrate that the antibodies specifically bind to recombinant receptor protein and that a subset of the binders inhibits mouse ST2L activity in multiple in vitro assays. Four of the identified anti-mouse ST2L antibodies were shown to prevent IL-33 from binding to ST2L, down-regulate IL-33-induced NF-κB signaling, and neutralize the ability of IL-33 to stimulate mouse Th2 cell proliferation. The characterized monoclonal antibodies are important tools that will be used to study mouse ST2L receptor functionality in vivo.

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.
