Beyond Unconventional: What Do We Really Know about Group 2 Innate Lymphoid Cells?
Bibliographic record
Abstract
Group 2 innate lymphoid cells (ILC2s) are a set of effectors that mediate the expulsion of helminthic parasites but also drive allergic lung inflammation. As innate agents, they do not recognize Ag, instead, they are sensitive to alarmin engagement, upon which they produce type 2 cytokines that amplify adaptive immunity. Their lymphoid identity appoints them as an intriguing group of unconventional cells; however, increasing evidence is unraveling a series of unprecedented functions that <5 years ago were unthinkable for ILC2s, such as acquiring a proinflammatory identity that enables them to support TH1 immune responses. Their plastic nature has allowed the characterization of ILC2s in more detail than ever; however, the novelty of ILC2 biology requires constant updates and recapitulations. This review provides an overview of ILC2s and describes memory ILC2, regulatory ILC2, inflammatory ILC2, and type 1 ILC2 subsets based on activation status, tissue environments, and function.

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; both teacher heads agree on what is shown here.
