Invasion of epithelial cells represents a potential pathogenic mechanism forPseudomonas aeruginosa. We explored the role of mitogen-activated protein kinase kinases (MEK 1/2) and the extracellular signal-regulated kinases (ERK 1/2) inP. aeruginosainvasion. Treatment of corneal epithelial cells with MEK inhibitors, PD98059 (20 μM) or UO126 (100 μM), reducedP. aeruginosainvasion by ∼60% without affecting bacterial association with the cells (P=0.0001). UO124, a negative control for UO126, had no effect on bacterial internalization. Infection of cells with an internalization-defectiveflhAmutant ofP. aeruginosawas associated with less ERK 1/2 tyrosine phosphorylation than infection with wild-type invasiveP. aeruginosa. An ERK-2 inhibitor, 5-iodotubercidin (20 μM), reducedP. aeruginosainvasion by ∼40% (P=0.035). Together, these data suggest thatP. aeruginosainternalization by epithelial cells involves a pathway(s) that includes MEK and ERK signaling proteins.
