Figure 3. Effects of CE-CKC emulsions and DXM on gene expression in PBMCs following LPS stimulation. Peripheral blood mononuclear cells (PBMCs) were preincubated for 30 min with cationic emulsions of cetalkonium chloride (CE-CKC) or dexamethasone (DXM). The cells were then stimulated with lipopolysaccharide (LPS) for 24 h. Emulsions were omitted during LPS stimulation, whereas DXM was present. Results are expressed as a percentage of the unstimulated control (set at 100%). Experiments were performed in duplicates.
