[Transfection of dominant negative MyD88 decreases IL-8 production in bacteria-infected airway epithelial cells].
Bibliographic record
Abstract
Interleukin-8 (IL-8) is an important activator and chemoattratant of neutrophils and has been implicated in airway inflammatory diseases. To explore the new gene therapeutic strategies for airway inflammation, plasmid expressing dominant negative myeloid differentiation protein (MyD88 DN) was constructed and transfected into human airway epithelial cell lines A549 and SPC-A-I. The cells were challenged with M. tuberculosis, P. aeruginosa or K. pneumoniae and the release of IL-8 was measured using ELISA. The results showed that the supernatants of M. tuberculosis and R. aeruginosa enhanced IL-8 release from the epithelial cells; and transfection of MyD88 DN diminished this effect. MyD88 DN also reduced IL-8 release from cells induced by live bacteria of P. aeruginosa or K. pneumoniae. These data suggest that MyD88 could be used as a target gene in the gene therapy of airway inflammation.

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.
