Novel signaling function of hCLCA1 in airway macrophages activation (1095.2)
Bibliographic record
Abstract
The CLCA gene family produces both secreted and membrane‐associated proteins that modulate ion‐channel function, drive mucus production and have a poorly understood pleiotropic effect on airway inflammation. In airway inflammation, the primary up‐regulated human CLCA ortholog is hCLCA1. Here we show that secreted hCLCA1 is able to activate macrophages, inducing them to express cytokines and to undertake a pivotal role in airway inflammation. Conditioned media collected from HEK293 cells heterologously expressing hCLCA1 increased the expression of pro‐inflammatory cytokines (IL‐1β, IL‐6, TNF‐α, and IL‐8) in U‐937 monocyte‐macrophage cell line. Similar pro‐inflammatory response was achieved in primary porcine alveolar macrophages activated with hCLCA1 conditioned media, showing that the effect was not cell line dependent. Immuno‐purified hCLCA1 at physiologically relevant concentration of ~100 pg/mL was also able to elicit pro‐inflammatory response in macrophages. These findings demonstrating that secreted hCLCA1 is able to function as a signaling molecule and to regulate cytokine expression in macrophages. Grant Funding Source : NSERC

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.
