Lactoferrin interacts with SPLUNC1 to attenuate lipopolysaccharide-induced inflammation of human nasal epithelial cells via down-regulated MEK1/2-MAPK signaling
Bibliographic record
Abstract
The short palate, lung, and nasal epithelium clone 1 (SPLUNC1) protein is an important innate material in the upper airway, and lactoferrin (LF) aids the innate functions in humans. In this study, a nasal epithelial model was used to investigate how LF modulates SPLUNC1 to reduce the inflammatory process mediated by lipopolysaccharide (LPS). The inflammation of human RPMI-2650 cells was induced with LPS to evaluate SPLUNC1 expression after treating the cells with bovine LF (bLF). The interaction pathway between LF and SPLUNC1 in LPS-induced inflammation was further investigated. Our study reveals that the addition of bLF results in the recovery of SPLUNC1 expression in nasal epithelial cells under LPS-induced inflammation. MAPK is involved in the main pathway for the SPLUNC1 and bLF interaction. Decreased SPLUNC1 function could be recovered by addition of bLF. The MEK1/2-MAPK signaling pathway is crucial for the SPLUNC1 and bLF interaction. Therefore, LF could support SPLUNC1 in the innate immunity recovery process.

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; a candidate call from one teacher head, not a consensus.
