MAPK14 and bronchiolitis obliterans syndrome: Phosphorylation of p38 on Thr-180/Tyr-182 was significantly increased in the BO-group (Control vs. BO; 100 ± 27 vs. 149 ± 16%, P < 0.05 vs. Control), and the increase was suppressed by Cap (BO vs. BO + Cap; 149 ± 16 vs. 85 ± 14%, P < 0.01 vs. BO) (Fig. 6C).
