Time-dependent cytokine secretion from differentiated HL-60 cells after S100A8/A9 or S100A8/PhosphoA9 stimulation. Cytokine secretion was measured by cytometric bead array upon stimulation with 3 μg/mL S100A8/A9 or S100A8/PhosphoS100A9 for 30 min to 6 h. Tumor necrosis factor alpha (TNFα) (A), interleukin (IL)-6 (B), CCL2 (C), CCL3 (D), CCL4 (E), or CXCL8 (F) concentrations were divided by LDH values in order to correct for cytokine release by cell death. Results are presented as mean ± SEM of three independent experiments. *p < 0.05; **p < 0.01; ***p < 0.001; ****p < 0.0001.
