Figure 4From: ROS-mediated TNF-α and MIP-2 gene expression in alveolar macrophages exposed to pine dustTNF-α and MIP-2 protein release of alveolar macrophages after 4 h of stimulation with 200 μg/ml pine dust in the absence and presence of GSH (6 mM) or NAC (20 mM). (A) TNF-α release, (B) MIP-2 release. Values represent means ± SEM of six separate experiments performed in duplicate. *p < 0.05 compared with PD or HPD without GSH or NAC treatment.Back to article page
