TNF-α levels in the M0, M1 and M2 dTHP-1 macrophage phenotypes exposed for 24 h to various concentrations of Printex-90, NM-400 and Mitsui-7-JRCNM40011a, or 1 µg/mL of LPS. Each bar represents the mean ± SD of three independent experiments (n = 3). “*” indicates a statistically significant difference from the control group, of each respective phenotype, by the one-way ANOVA, followed by Dunnett’s multiple comparisons test with p < 0.05.
