Campylobacter jejuni induces diverse kinetics and profiles of cytokine genes in INT-407 cells.

Objective: To examine the kinetic ability of embryonic human epithelial INT-407 cells to express messenger ribonucleic acid mRNA for various cytokines and chemokines in response to Campylobacter jejuni C. jejuni stimulation.

Methods: In an experimental single-blind study, cultured embryonic human epithelial INT-407 cells were treated with different concentrations of viable C.
