Pathogenic IgE-fated memory B cell responses retain functional plasticity
Bibliographic record
Abstract
Abstract Long-lived immunoglobulin (Ig) E responses against innocuous environmental and dietary antigens (Ags) are maintained by an IgG1-dominant memory B cell (MBC) compartment primed for IL-4 responsiveness. The plasticity of the MBC compartment destined for IgE class switch recombination (CSR), however, remains poorly understood. In this work, we report a critical IL-4/IL-13 dependency for the pathogenic IgE fate of type 2-polarized MBCs. Initiating a recall response in the absence of IL-4/IL-13 signaling diminished the type 2 MBC phenotype in mice and humans and, in mice, permitted the emergence of long-lived Ag-specific IgG2c + MBCs. The divergence to a type 1-like response was dependent on IFN-γ signaling and arose from both unswitched and class-switched Ag-specific B cells in vivo . This reprogrammed fate was sustained even beyond therapeutic intervention, revealing fundamental insight into the plasticity of the allergen-specific MBC response. One Sentence Summary B cell responses to allergens can be reprogrammed away from a pathogenic fate through IL-4/IL-13 signaling blockade.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
