Figure 1From: Nontypeable Haemophilus influenzae induces COX-2 and PGE2 expression in lung epithelial cells via activation of p38 MAPK and NF-kappa BThe mRNA expression of COX-2 but not COX-1 induced by NTHi in a dose-dependent manner. A549 cells were inoculated with different concentrations of NTHi, as indicated in the figure, and mRNA expression of COX-1 and COX-2 was measured by RT-PCR analysis.Back to article page
