p38, PI3K and ROCK inhibition modulates signalling in alveolar macrophages.

(A-F) COPD alveolar macrophages (AM) were pre-treated with the designated concentrations of SCIO469 (A) VX745 (B), NVS-PI3K-2/3/5 (C-E), or PF4950834 (F), were then challenged with S. pneumoniae for 6 h, before cells were lysed and probed for either p-HSP27 (A-B), p-AKT (C-E), or p-MLC (F). Plots are representative of three independent experiments and densitometry from all three experiments are shown, * = p<0.05, ** = p<0.01, ANOVA with Dunnetts post-test vs control.
