A549 cells were treated with 10 µM simvastatin or an equivalent amount of DMSO (VEHICLE) for 24 hours. Untreated and statin-treated cells were subsequently infected with P. aeruginosa PAO1 for 3 hours at MOI 50∶1. The expression of (A) KLF2 (B) KLF6 (C) IL-8 (D) CCL20 and (E) TLR5 was analysed in uninfected cells, and in the presence of vehicle, simvastatin (SIM), P. aeruginosa (PAO1) and simvastatin and PAO1 combined (SIM+PAO1). *P, ≤0.05, **P, ≤0.01, ***P, ≤0.001.
