Fig. 1From: Differential Activation of MAP Kinase Signaling Pathways and Nuclear Factor-κB in Bronchoalveolar Cells of Smokers and NonsmokersDose response of activation of NF-κB in LPS-stimulated AM from smokers and nonsmokers. AM were tested immediately after isolation (line 1) or after 30 min incubation with LPS 0–10 µg/mL (line 2–7). Gel shift assays were then performed. Representative data from one smoker (upper panel) and nonsmoker (lower panel) are shown.Back to article page
