Inhibition of e-cig induced MMP-9 release. Neutrophils from six healthy subjects were pre-incubated with dexamethasone (dex; 1 μM), selumetinib (Sel; 1 μM) or BIRB-796 (1 μM) for 1 h prior to ECVE (0.003) exposure for 6 h. Supernatants were analysed for MMP-9 by ELISA. Data presented as mean ± SEM where * = significant increase compared to unstimulated control (p < 0.05)
