A very low concentrations of lipopolysaccharide induce the production of TNF-α and IL-6 in monocytes. PBMCs (n = 3) were stimulated with the indicated concentrations of LPS or in the absence of LPS (Control). CD14+ monocytes were gated and the bar graphs indicated the relative mean fluorescent intensity (MFI) of TNF-α (a) and IL-6 (b) are expressed as mean ± standard error of mean (SEM). Statistical analysis was performed using one-way ANOVA with Tukey’s multiple
