Phosphorylation of p38 MPAK induced by NTHi. A. A549 cells were inoculated with 10 and 50 MOI of NTHi, and phosphorayltion of p38 MAPK was detected by Immunoblot analysis. B: A549 cells were inoculated with 50 MOI of NTHi with or without 20 μM of SB203580, and phosphorayltion of p38 MAPK was detected by Immunoblot analysis. A & B: representative blots from three independent experiments.
