Abstract

fetched live from OpenAlex

Vibrio parahaemolyticus is the leading cause of gastroenteritis from seafood consumption. We tried to determine how the gene expression levels of intestinal-like epithelial cells (Caco-2 cells) and mouse intestinal loop mucosal cells change upon infection with this bacterium. Since we found the robust production of interferon alpha (IFN-alpha) by the V. parahaemolyticus infection, we also assessed the upregulation of a number of IFN-stimulated genes (ISGs). The expressions of IFN protein were determined by Western blotting, and the gene expressions of Caco-2 cells after V. parahaemolyticus infection were determined by quantitative real-time reverse-transcription polymerase chain reaction. Three ISGs (i.e., IFN-alpha-inducible protein 15, IFN-alpha-inducible protein 6-16, and IFN-induced protein with tetratricopeptide repeats 1) were upregulated by V. parahaemolyticus infection. Infection induced the production of IFN-alpha, but not IFN-beta or IFN-gamma. The upregulation of the 3 ISGs was suppressed by treatment with a neutralizing IFN-alpha antibody. Moreover, the production of infection-induced IFN-alpha was found in the mouse intestinal loop mucosal cells. V. parahaemolyticus infection of Caco-2 cells results in IFN-alpha production and the expression of IFN-regulated genes.

Not 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.
