Abstract
The complement (C) plays an important role in many acute inflammatory processes. C3a is an inflammatory polypeptide named anaphylatoxin, generated during C activation and which acts through a specific receptor C3aR. In this study, we demonstrated that the epithelial cell line ECV 304 constitutively expressed C3aR (by flow cytometry and immunofluorescence) and that binding of purified C3a to epithelial cells resulted in a time- and dose-dependent upregulation of interleukin-8 (IL-8). Pre-treatment of ECV 304 with pertussis toxin inhibited IL-8 response induced by C3a, indicating that the action of C3a was mediated by a G protein coupled pathway.

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 it
