Figure 2. Effects of the cationic emulsions of cetalkonium chloride (CE-CKC) emulsions, IKK Inhibitor X (IKK Inh X), dexamethasone (DXM), and cyclosporine A (CsA) on IL-6 and IL-8 release by HCE-2 cells following lipopolysaccharide (LPS) stimulation. Results are expressed as mean ± standard error of the mean (SEM) of the percentage of inhibition versus LPS-stimulated cells. *, p<0.05; **, p<0.01; ***, p<0.001. Experiments were performed in triplicates.
